How to install a car alarm yourself

Installing a car alarm

Probably, almost every driver, at least once in his life, has tried to independently install an alarm system in his car, mainly of a domestic brand, since for some foreign cars a high-quality alarm system may already be included.

The process is not easy, requiring experience and knowledge , since it can lead to breakdown and short circuit of the electronics, and damage to the security system itself. Therefore, if you do not have the appropriate knowledge and skills, we do not recommend installing an alarm; it is better to contact a car service center.

There are specialists working there who can be entrusted with such work, and in the event of a breakdown or incorrect installation, they will be held responsible.

How to install?

Statistics show that every year more and more new cars are bought with a simple security system, or without it at all. When buying a car secondhand, most car owners try to change the anti-theft system already installed on the car, since for some people, including the former owner, it will not be difficult to break into the car.

Based on this, installing an alarm system has become a standard and customary measure when purchasing a car from a showroom or from the secondary market. But, it is worth noting that for the correct and competent installation of a new alarm system, you need to know where all the connection points of the security system are located.

Installation Guide

When purchasing an alarm kit, be sure to take the accompanying documentation; it should contain: installation instructions, as well as a vehicle electrical diagram. Only a person who has installed this model on your brand of car more than twice can undertake the installation of an alarm system without such documents!

Otherwise, if the attempt is unsuccessful, you can spend a lot more time and money on repairing and restoring electronics. As a rule, in the instructions for the alarm system, all designations of connection points are standard.

However, finding them on the diagram of your car is not an easy and time-consuming process, so if you do not have even the most basic knowledge of electronics, or you feel that installing an anti-theft system yourself will be difficult, contact a qualified technician immediately.

And if you want to complete the installation following the advice of someone - a specialist you know or messages in online forums, make sure once again that they are talking about your brand of vehicle and your model of security system.

Ask the store where you bought the car alarm for specialized additional instructions or a connection manual, but unfortunately, recently, only a small part of manufacturers of car security systems have published such instructions.

There can be a great many reasons for this. Therefore, if you decide to install an anti-theft alarm yourself, try to find as many instructions, manuals and diagrams as possible, identifying all connection points.

Where are the connection points located in the car?

In almost all brands and models of cars, the locations of the security alarm connection points are the same, however, the connection points themselves are almost always different. The only exceptions may be some exclusive models of certain brands.

Connection points

The location of the points in the internal wiring, in the switching unit, at the bottom of the front panel of the car is the most popular and frequently encountered option. In foreign cars, this block is located on the platform for the left foot, or near the clutch pedal.

In new domestic cars produced after 2010, this block will most likely be to the right of the gas pedal, and on cars before 2010 - to the left of the steering column.

But finding the junction box itself in the car will not be very difficult; it is much more difficult not to disrupt its operation, since any inept intervention will immediately affect the work and all the electrical equipment of the car.

To do this, we will say once again that you need to carefully review and understand all the instructions and understand your further actions in detail so as not to cause damage to your car.

In the ignition switch, from which many electrical wires and power lines lead, there is another place where there is a cluster of alarm points. In this place, most likely, there will be “ACC”, a starter and positive terminals, which will be typical for a more expensive type - an alarm system with automatic start.

It is to connect such a warning system that you need to find this section of the vehicle wiring on your electrical circuit. In addition, now in many cars it is mandatory to connect the central locking to your alarm system.

It is usually located in the car's interior next to the junction box, but if you replaced it after purchase, its location becomes unknown.

In practice, there have been cases when it was installed both under the passenger or driver’s seat and under the hood.

The unit itself may have different polarity options, which will definitely affect the connection method, so if possible, look for documents for it so as not to damage it when opening it.

In any car there are specialized holes through which many wires lead, and usually it is in this place that the alarm system that controls the fuel pump is connected. The front left threshold most often serves as the connection point for the central locking, side lights and sirens.

Car service specialists, who install a variety of alarm models on cars every day, find almost all connection points for the security system in this place. This is also extremely convenient - when replacing or repairing the alarm system, you will only need to open the casing in this place.

Sometimes, after trying all the options listed, you cannot find the necessary connection points and the necessary wires, and in this case we recommend using the “primitive method”. To do this, you purchase new wires and connect them to the contacts of the following elements: brake and clutch system, emergency parking button, dimensions.

However, it is worth noting that this method is not called “primitive” for nothing - due to the large number of additional wires, their entanglements and bends, it can break quite often.

But it happens when, apart from this method, there are no other options.

Sometimes such a mechanism is used as a temporary one, since it is not always possible to immediately find a good specialist for an acceptable amount, so some car enthusiasts are ready to resort to such extreme measures.

Necessary tools and recommendations

You should have an electrical tester in your tool kit to check contacts, so you don't have to use a light bulb for this purpose. Using a light bulb can cause electrical problems and ruin your new alarm. It is also worth purchasing Phillips and flat head screwdrivers and a 40 W soldering iron.

Tools

In general we will need:

• Screwdriver Set.
• Key for 10.
• Wire insulation tape.
• Double tape.
• Device for measuring voltage.
• Wire stripping tool.
• Something to insulate the machine.

If you still doubt the correctness of the decision to install an alarm system yourself, especially if it is expensive, then we advise you to contact a specialist or at least get qualified advice. The average price for installing security systems ranges from 2,000 to 40,000 rubles , and depends on the model of your car and, of course, on the model of the purchased alarm system.

How to install a car alarm yourself

The safety of a car, especially a new one, is a very pressing problem for the modern car owner. There are several ways to protect your car, the most popular of which is to install an automatic alarm on it.

Installing an alarm system in a specialized center takes little time and guarantees the quality of the work performed. But there are also disadvantages.

The first of which is the high cost of work, the second is the use of standard equipment placement, connection and wiring diagrams.

But if you have a simple tool and certain skills, installing a car alarm yourself is a completely doable procedure.

Equipment and materials

Car alarm kit

When choosing an alarm kit, you should adhere to the rule that the cost of it should be 3-5% of the cost of the car. Installing a security kit worth 150 thousand on a car worth 300 thousand rubles will be clearly unreasonable.

To install the selected alarm kit on your car you will need:

car set of locksmith tools; wire stripper; heat shrink tube and lighter; electrical tape in the color of the car wiring insulation; multimeter or other device for measuring voltage and conductivity; double sided tape; splen or ordinary foam rubber; car electrical diagram.

Installing an alarm with your own hands will require care and patience; you will have to disassemble the front panel, steering column cover and other interior trim elements.

Installation of equipment

At the first stage of installing the alarm, you should understand the alarm itself, for which you should study the attached instructions.

Next, you need to understand the electrical wiring of the car, for which you will need a diagram of its electrical equipment. The next stage involves choosing the location for installing the control unit and signaling device.

If with the first everything is clear, it is installed in the most inaccessible place - under the front panel, then with the second it is not so simple.

It is usually placed under the hood, but each car model has a limited number of available places in the engine compartment where you can easily install a siren.

The more difficult it is to get to the source of the sound signal, the more difficult it is to turn it off. When disassembling the front panel and steering column casing, plastic clips may be used, so for installation it is better to use special plastic clips. This way you will protect the casing from damage.

To install the alarm you will have to disassemble part of the dashboard

Electrical connection

The alarm outputs must be connected to the direction indicators or side lights of the car, to the light bulb responsible for indicating the opening and closing of doors, as well as to the engine running indicator lamp.

If your car's panel is optitronic, then the only thing that can be connected is the turn signals.

In order to install the wires, on the back of the panel you need to find the light bulbs responsible for indicating the turn signals are turned on.

We find a board of light bulbs, tracks are applied to it. You need to find a 12-volt contact and check it, for which we connect the connector to the track, turn on the turn signal and throw in a multimeter. If you have found the required wire, the multimeter will show the presence of voltage at the moment the turn signal lamp comes on.

Note!

Searching for wires using the “light bulb” principle is unacceptable when working with a car’s electrical system. Using this method can be costly for the car owner, because you can easily damage the entire power supply system of the car.

As a matter of fact, we look for the wire responsible for opening and closing doors using the same principle.

When the car door is open, the multimeter reading should be equal to 12 V, and therefore, when the door is closed, it should be equal to 0. We find the control wire for starting the engine using the same method. However, if in your car this function is performed by the tachometer, then it will not be possible to test it in this way.

The alarm connection diagram provides for the connection of the control unit and the central locking of the car.

The best way to do this is by connecting to the lock activation relay. We will look for it by analogy with previous actions.

Wiring

When laying alarm wires, you should assemble them in directions into bundles and wrap them with electrical tape. The insulating tape should not differ much from the factory insulation of the wires. This will make it much more difficult for car thieves to find wires to cut. In addition, the use of electrical tape serves as additional insulation for the wires, increasing reliability.

It is best to solder the wires to the connectors and insulate them with heat shrink tubing, and then wrap them with electrical tape.

When connecting wires, you can use special clamps, but their use significantly reduces the time it takes for a thief to determine the right wire.

When laying wiring under the hood (connecting a limit switch and siren), the wires should be laid along existing bundles of electrical wires, making them less noticeable.

A properly installed alarm system will help protect your car from burglary.

Powertrain blocking

Installing an alarm on a car also means blocking the engine if the car is started unauthorized. Most often, the ignition switch connector is used for this. To determine the required connector, you need to ring the lock.

The wire that has voltage when the key is in the “ON” position is selected and disappears in the “Start” position. To block the engine, remove the connector from the ignition switch and close this wire with a jumper to a constant plus, and with a second jumper, a constant plus and the starter terminal.

If the engine starts, then remove the jumper to the starter, the car is turned off and the found wire is cut. Next, the alarm wires and the cut ends of the wire are connected. The connection should be insulated using heat-shrinkable tubes and the same electrical tape.

Installation of a car alarm using the example of a VAZ 2110

The installation of a car alarm in a VAZ 2110 car can be divided into 2 levels: installation of all elements of the alarm system and connection to the car’s electrical circuit. The most labor-intensive work, perhaps, can be called installing electrical wiring in the doors and trunk of the car.

This is what the central alarm unit looks like with the wires connected to it. This is a shock sensor (shock sensor) connected to the central alarm unit. This is what the wiring harness connected to the unit looks like, leading to the sensors for opening/closing the trunk and hood, car doors, as well as the siren and lighting equipment If there is only one block on the central unit of the alarm system you have chosen, and you need to connect two sensors, the connection is made in parallel. The process of installing an alarm system on a VAZ 2110 car. The hood and trunk opening sensors are mounted in such a way that a short to ground occurs at the very beginning of opening . To install the hood opening sensor, we make an additional fastening. To do this, we use the mounting plate for the electric door lock drive. After securing the bracket, insert the sensor into it, adjust it in height and fix it in the selected position using the lower nut.

Armed with an ohmmeter, we check how securely the sensor is connected to ground. The sensor for the trunk is installed in the same way.

As practice has shown, it is best to mount the siren under the hood on the connector of the right mudguard. Do not forget that it is better to point the horn down to prevent moisture from entering it.

We fix the shock sensor (impact sensor) under the dashboard using self-tapping screws.

The microwave sensor is best placed in the central part of the car. Installation instead of the standard rear ashtray is good for this purpose.

The ashtray must be dismantled, its holder removed and the sensor installed in it. The sensor wiring is laid in the lining of the central tunnel.

The sensor must be securely mounted so that it can well perceive all body vibrations.

The central unit is installed behind the injection controller. The last stage is the installation of the pager transmitter. We attach the sensor to a degreased windshield, having first removed the film from it.

The wiring from the sensor is hidden under the lining of the windshield pillar.

We make the bracket from the mounting plate of the electric door lock. We fix the bracket. We insert the sensor into the bracket. We fix the sensor. We check how securely the sensor is connected to ground using an ohmmeter. We install the trunk opening sensor in the same way. It is best to mount the siren under the hood on the connector of the right mudguard. We remove the ashtray. We install the microwave sensor in the holder. ashtrays The central unit can be installed behind the injection controller The pager transmitter is attached to the windshield

We connect the wiring in accordance with the diagram attached to the alarm system you have chosen.

Examination

The installed car alarm is checked in all operating modes and adjusted to suit you. When checking, you need to open all the doors, trunk and hood sequentially. When each element is opened, the security alarm should go off, and the engine should be blocked if an unauthorized start is attempted.

You also need to adjust the sensitivity of the shock sensor. To do this, there are holes in its body in which small bolts for a Phillips screwdriver are visible. As you can see, installing an alarm yourself will require time, a simple tool and a little courage.

Let's sum it up

Installation of wires should be carried out as discreetly as possible; existing harnesses can be used; The siren is installed in the most inaccessible place; The wires should not be under constant voltage, this may lead to a fire; When the engine lock is triggered, no error should appear on the instrument panel; it can easily identify the blocked circuit.

How to connect an alarm

Car alarm connection:

The modern realities of our lives make the installation of a car alarm one of the most pressing problems. First of all, it ensures reliable protection of the car from attempts at break-in and theft.

Currently, motorists are offered the widest selection of alarm systems. And then the question of how to connect the alarm to a specific car comes to the fore.

However, first of all, it is necessary to consider the main types of these devices and make the right choice.

Types of modern alarms

Any car alarm can perform several basic functions. All of them, in one form or another, are present in every design.

First of all, these devices must respond to all actions towards the car that are illegal. Many of them can block the engine, preventing unauthorized start attempts.

In such cases, a good alarm attracts not only the attention of the car owner, but also the people around him.

Based on functionality, modern alarm systems are divided into the following types:

1. Alarm without feedback . This design is a budget option and is installed mainly on inexpensive cars. The radio channel is considered the most vulnerable point. This car alarm is not capable of protecting the car from experienced car thieves, however, it may well scare away petty thieves.
2. Alarm with feedback function . Compared to the first option, it is capable of solving a much larger number of problems. That is why it is so popular among drivers. With the help of feedback, the car owner remotely receives information about his car, which is sent to a special key fob. In addition to security functions, it is possible to remotely start the engine. You just need to disable the mobilizer installed at the factory. In urban conditions, the range of such an alarm is up to 1 km.
3. Using GSM alarm system with GPS module . These devices are becoming increasingly popular due to the ability to control a car via a mobile phone. Thus, you can track your car from anywhere, provided the network of the service operator is covered. All information is transmitted in both directions via SMS. Some operators provide a service that makes it possible to track the position of a vehicle linked to a map via the Internet. With this service it will be much easier to find a stolen car.
4. Satellite signaling belongs to the field of high technology. The level of protection allows it to be used in expensive cars. All information is transmitted via communication satellites. This is the most reliable and expensive type of car alarm.

A wide selection of electronic devices allows you to choose the most suitable car alarm option, which includes all the necessary functions. After purchasing, you can install it. To solve this problem, there are two ways: contact a car service center, an experienced auto electrician, or try to install an alarm on your car yourself.

Rules and procedure for installing alarms

If you do not have knowledge of electrical engineering, you should not try to install the alarm yourself. These devices are quite complex and require special knowledge and skills to operate them.

After all, the electrical circuit of the alarm system will be combined with the electrical network of the car at many points.

The slightest inaccuracy in installation can lead to failure of various relays, blocks and other elements.

There is a certain installation procedure that must be followed. First of all, the places where the main alarm elements will be installed are determined.

Typically, an electronic control unit, sensors, antenna, light and sound signals are used for this. The mistake of many car owners is trying to make design changes to the circuit or randomly connecting individual elements.

At best, such equipment simply will not work.

The main connection point for the alarm is the control unit, in which all the wires are concentrated. This greatly simplifies the connection. In addition, the unit is located under the instrument panel, in a hard-to-reach place. After determining the connection locations, you can proceed to the actual installation of the device.

Alarm connection procedure:

• Installation of sensors in places recommended by the manufacturer.
• Installing a sound siren under the hood of a car.
• Sensors, sound alarms, light sources are connected to the control unit in accordance with the diagram.
• At the end of installation, the unit is connected to the power source.

As a rule, this procedure does not cause any particular difficulties. You just need to carefully understand the connection diagram supplied with the equipment. There are certain connection difficulties with central locking. In such cases, you have to individually understand the circuitry of each car.

Connecting an alarm to a car with central locking

Most modern cars are equipped with central locking. Along with a security alarm, it also performs protective functions. Therefore, these individual systems must work in harmony, and this depends on correct installation.

The main function of the central locking system is to open and close the locks located on the doors, trunk, hood and fuel filler flap. When the driver's door closes, other body elements are locked at the same time.

To control the central locking, there is a button installed in the cabin and a key fob with a remote control.

Considering the features of both devices, it should be remembered that the car alarm and central locking circuits must be compatible with each other, and their operation must occur synchronously.

After installing the alarm, additional useful functions appear in the car:

• Automatic closing of the sunroof and lowered door windows.
• Upon command from the control panel, you can remotely start and warm up the engine.
• Create a simulation of an engine breakdown so that the thief lingers in the cabin.
• Complete blocking of engine starting.
• Driving a car using SMS messages.

In some cases, the installation of a car alarm is carried out simultaneously with the central locking. This makes it possible to immediately combine the electrical circuits of both devices.

DIY alarm installation rules

In some cases, mainly in the absence of service centers, car owners try to install the alarm themselves. This matter is not at all hopeless. You just need to follow the basic rules for installing such devices:

1. All connections of wires to each other and to device elements are made through terminals or by soldering. All connections must be carefully insulated.
2. The wiring is carried out hidden, under the interior trim. Particular attention should be paid to the transitions between body elements.
3. During the connection process, the colors of the wires must be observed in the same way as in the attached diagram.
4. During work, the battery must be completely disconnected.

Installing car alarms with your own hands with auto start: video

Almost all cars are currently equipped with security systems, which are presented on the domestic market in a huge range. Conventionally, all such devices can be divided into three categories:

1. With one-way communication, with a minimum set of functions and low cost. Currently, such devices are almost not in demand among car owners.
2. With feedback, allowing you to receive real-time information about the condition of the car on the remote control key fob. These alarms have a large number of functions, some of which are used extremely rarely. They belong to the middle price category and are the most popular among car owners.
3. Security systems equipped with microprocessors and satellite communications. As a rule, they are equipped with their own power supply and make it possible to control the condition of the car using smartphones. Their cost is quite high, and therefore they are usually installed on expensive luxury cars.

Naturally, owners of VIP-class cars, having purchased an expensive security system, will not install it themselves, however, for owners of relatively inexpensive or used cars, the process of installing an alarm system with their own hands may be interesting. There are several reasons for this:

• the family budget does not allow contacting service station specialists;
• the desire to install the alarm yourself, without entrusting this procedure to professionals;
• the use of a non-standard (homemade) design, which is refused to be installed at service stations.

DIY alarm installation

Installing an alarm system in your car yourself is not that difficult. You only need to have the skills to carry out auto repair and electrical installation work.

Equipment

Any alarm, regardless of model and manufacturer, includes:

1. Base unit.
2. Remote control.
3. Sound signaling device (siren).
4. Transceiver device or antenna.
5. Motion or shock sensors.
6. Set of wires.

Required tools and materials

When starting to install an alarm system with your own hands, it is advisable to prepare the tools and auxiliary materials that may be needed during the work. First of all, you should have at hand:

1. Electronic multimeter (tester).
2. Set of wrenches and screwdrivers.
3. Knife for cutting and stripping wires.
4. Insulating tape.
5. Double sided tape.
6. Foam rubber.

After all the documentation has been studied, the necessary materials and tools have been prepared, you can safely begin work. To do this, you need to determine the location of all the components and the points of connection to the vehicle’s on-board electrical network.

Placement of main components and wire connection points

Most often, the individual elements included in the alarm system are placed:

1. The base unit is in the steering column area, near the fuse box. There is a lot of space in this area and this is where the main cable harnesses are laid. In addition, the ignition switch is located in close proximity. When installing the base unit, it is recommended to wrap it with foam rubber. This will reduce the impact of vibration when the vehicle is moving.
2. Siren - in the engine compartment.
3. The shock sensor is under the dashboard.
4. The transceiver or antenna is located under the trim, as close as possible to the windshield or directly on it.

Having installed all the alarm elements, proceed to connecting all the elements to each other and connecting the wires to:

• direction indicators or side lights;
• electric windows (if equipped);
• central lock. If there is no central locking, it must be installed.

In this case, the main wire connection points are located:

1. In the ignition switch:
   • positive polarity: ACC wire, ignition, “+” contact;
   • negative polarity - starter.
2. In the door area: positive polarity - limit switches, the installation location of which is determined by the design of the vehicle.
3. Under the steering column trim: positive polarity - turn switch.
4. Under the dashboard trim: positive polarity - side light switch.
5. Steering column space: positive polarity - “frog” brake pedal.
6. Central locking - negative polarity: placement of control buttons according to the vehicle design.

Step-by-step connection of system elements

All electrical connections are best made using jumper terminals or soldering. Twisting wires is not reliable. The elements are connected as follows:

1. The visual (light) indication is connected to the wires coming from the direction indicators or side lights. In the first case, these wires converge at the alarm button, in the second, they are connected to the control wire of the power relay. In practice, they often use a connection to the wires of the turn switch.
2. Connecting the hood and trunk limit switches pulls separate wires and connects them to the corresponding wires of the base alarm unit.
3. Separate wires are also pulled to the door limit switches. In this case, it is necessary to ensure that these wires are not damaged when opening/closing the doors. It is recommended to protect the bend points with rubber tubes.
4. The connection to the central locking is made on the control unit. Its location depends on the design of the car. It can be located on the driver's door or on the center console.
5. The siren and shock sensor are also connected by wires going to the base unit.
6. To connect the transceiver, separate wires are used, which are hidden in the interior trim. They are laid separately from all the others - this allows you to avoid false alarms as a result of electromagnetic interference.
7. The base unit is connected to the ignition switch by laying a pair of separate wires between them.
8. Connecting the wires that supply power to the base unit requires special attention, since reversing the polarity can damage the alarm system.
9. The system connection procedure ends by connecting the base unit to the vehicle ground. To do this, use a separate wire, which is attached to the car body with an M6 or M8 bolt with the corresponding washers and nuts. It is recommended to paint this connection to avoid self-loosening.

Installing a car alarm with auto start

A car alarm with auto start is a new generation anti-theft system that makes it possible to start the vehicle's engine from a remote control.

In addition, it allows you to configure the automatic start of the engine and other vehicle systems, which significantly saves the driver’s time. In this case, the periodic start of the power unit is the main setting of a large number of functions performed by such an alarm.

However, as often happens, with advantages come disadvantages. Thus, alarms with auto start require a more powerful battery, since the auto start system takes a significant part of the battery’s energy. In addition, there are models in which the autostart function prevails over the security functions of the system.

Installing an alarm system with auto start is somewhat more complicated than installing models of previous generations. This is due to the need to bypass the immobilizer. At the same time, the effectiveness of the car’s security system is somewhat reduced.

There are several ways to bypass the immobilizer when installing an alarm system with auto start:

1. Purchase an alarm system with a built-in immobilizer bypass unit, which turns on when it receives a corresponding signal from the remote control. This option does not reduce the effectiveness of the security system.
2. Purchase an immobilizer bypass unit, which, when installed in a car, allows (depending on the version):
   • disconnect the standard device from a separate remote control, and then start the engine;
   • constantly send a signal to the immobilizer, simulating the presence of an ignition key in the cabin.

Such a block is connected as follows:

1. Install the lineman frame around the standard ignition frame.
2. Place the ignition key in the bypass module frame.
3. Place the wires from the ignition switch next to the power wires of the alarm system.

Tips and tricks

Experienced car enthusiasts who have repeatedly carried out work on installing car alarms recommend:

• when connecting alarm wires and car electrical wiring, use terminals;
• do not make changes or improvements to the design and connection diagram of the product;
• before starting work, find videos on the Internet that show the installation of exactly the model of device that you purchased, and carefully familiarize yourself with the procedure for performing all the necessary operations;
• do not start work if you do not have all the necessary tools and materials at hand;
• try to install all elements of the system in such a way that they are not noticeable to intruders;
• lay all wires only in dry places where moisture cannot enter;
• The wires are fastened using plastic clamps.

How to install a car alarm yourself?

A car alarm is an attribute that you cannot do without. When you leave your car under the entrance windows, it is very difficult to get rid of the annoying desire to run and see if the car is there. Any responsible driver knows this feeling.

Therefore, very often when thinking about buying a car, the future driver chooses the car that offers a standard alarm system from the factory.

As a rule, this anti-theft alarm system is not of very high quality, usually one-way, but its presence can save the car from theft and give the owner the desired peace of mind.

What are the alarm options?

Having used it enough and realized that the standard alarm does not satisfy the needs, the driver, as a rule, thinks about replacing it with a better model.

Car alarms can be different, so let’s figure out what they are, and then everyone will choose for themselves the option that suits them best.

Conventionally, by type, the entire car “alarm system” is divided into:

• Simple (one-sided).
• Complex (with feedback, in other words, two-way).

A regular car alarm, the one we call simple and the one that is most often supplied as a standard alarm, is a set of sound and light alarms and a central locking system.

The kit includes only one key fob with which you can disarm the car, put it under protection and open or close it. All that such an anti-theft alarm can do is loudly inform everyone around that someone wants to get this car for themselves.

This option can be successfully used if the car is not expensive and is not in demand among car thieves, and always sleeps in the garage.

If the car is expensive and you got this option as a standard alarm system, but you happen to leave the car in a sparsely populated area under the entrance, then, of course, such a model will not be enough.

Well, the car will “scream”, the sleeping owner will not even hear it, and everyone else will not care, and the thief will most likely successfully steal such a car. The solution in such a situation would be a two-way anti-theft alarm.

In terms of protection against theft, such a car alarm is more advanced. Let's consider a similar situation, when the car is also parked at the entrance and they want to steal it.

Car alarm with feedback

In addition to the fact that the car starts swearing loudly, its owner will immediately hear a signal from the two-way communication key fob. And, having seen this signal, there will always be time to run to the car and stop the theft. Next, we will pay attention to security against computer theft.

Now the automotive industry is directly fighting car thieves, who are coming up with more and more sophisticated ways to hack cars. So, with the advent of the ability to open a car using a key fob, they came up with special devices that pick up this signal and imitate it. Thus, the anti-theft alarm is deceived.

For example, at the moment when you lock your car, there is a thief next to you who caught the signal. But the code has already changed, and only the key fob in your pocket knows, and even after you open the car with it again, it will change again, and so on ad infinitum. It's impossible to pick it up. Such a car anti-theft alarm system is still practically unbreakable.

Self-installation of alarm systems

Let's assume that a certain car alarm has been selected and purchased.

The question arises: how to install it? Of course, the service station will easily solve this issue, but how much money it will cost to solve it is another question.

As a rule, this can cost up to 50% of the cost of the “signaling” itself. However, installing a car alarm is not that difficult; any driver can do it himself and save a lot of money.

Typically, the package includes everything you need and we only need the following tools:

• Soldering iron.
• Insulating tape.
• Multimeter.
• Any convenient pliers.

A multimeter will be needed to check the vehicle wiring functions. It is worth noting that it is not recommended to use a probe (an indicator, a kind of screwdriver with a light bulb).

Also, before starting all operations, you need to disconnect the negative terminal from the battery to eliminate the possibility of a short circuit.

If you don’t remove the terminal, you can accidentally short-circuit the wires, and the car’s wiring will completely burn out. It will be very difficult to replace it yourself and they will charge you a lot of money at the station, and the car most likely won’t drive until repaired.

First we will need to decide on the installation location of the main control unit. According to the recommendations of many auto mechanics, the best place for installation is the car steering column.

The advantages of choosing this particular place are that all the wires for connection will be nearby and ease of installation.

It also happens that car alarms are sensitive to the temperature inside the car, so you need to choose a place where there are no warm air flows and nothing heating up. Next comes the installation of all sensors.

All of them should be placed inside the car, since here they will not get wet and will work as they should. Anti-theft alarms always have a shock sensor; it is recommended to place it closer to the center of the car so that it perceives shocks and touches from all sides of the car at once.

Also, almost any car alarm has an LED indicator that notifies everyone who wants to covet the car about the presence of protection. All wires must be connected efficiently to prevent malfunction.

If some wiring falls off, the operation of the entire “signaling” may be disrupted. It is also worth paying attention to masking the main control unit. It is the car steering column that is immediately examined by an experienced thief for its presence.

It would be nice to make it less noticeable or hide it behind something.

You also need to check how the key fob works, how the car is disarmed and how it is disarmed.

It is worth understanding that a car alarm can become not just protection against thieves, but also a deterrent.

The thief will look at the flashing LED and think: “Why should I mess with a car that has a car alarm, I’ll go find a simpler car.”

And just the very fact of the convenience a car alarm creates already indicates that it is advisable to install it. The ability to open the trunk and doors without a key, a restful night's sleep and the absence of fear for the car are undeniable advantages.
