To date, car alarm is the most popular vehicle protection option from theft. Its main goal is to file a loud signal to the car owner of unauthorized penetration and, thereby scare away the criminal. However, this does not always give the desired result, it is because of this, more and more often, the car owners are interested in an immobilizer - a special device that does not allow the hijacking of the vehicle.

Immobilizer comes to protect the car when the penetration has already taken place. It turns off fuel and electrical circuits, when blocking which, it is impossible to start the car and start moving. Automotive immobilizer, as well as a lock with a key, folds from several parts. The first part of the device is directly in the car, and the second is usually built into the key. Insert the key to the ignition lock, the device works and recognizes correct this key or not. And the most interesting thing is that when removing the immobilizer, the motor will not work. To date, a very many modern car masters are equipped with a regular immobilizer.

Where is the immobilizer, how it works

There are several types of immobilizers:

1. Contact immobilizer.

2. Becade immobilizer with long-range radius.

3. Incontact immobilizer with a small radius.

4. Immobilizer, which manages the hood lock.

In fact, the immobilizer is not alarm, although such an opinion is quite common. This device is not able to notify the driver about an attempt to unauthorized access, it only immobilizes the car. For this, to achieve the maximum level of vehicle protection, you must install both devices at the same time. Law enforcement agencies assure that such measures are able to significantly reduce the number of crimes.

The scheme of the device can be compared with a switch that is controlled by electronics. A low-current chains are used through the device, which are used in the onboard circuit of the machine and are automatically discredited, upon receipt by an immobilizer of a special team. Depending on the settings and the exact device model, the shutdown occurs when the ignition is turned off, during a certain time there is no movement either when the radiometer is removed from the installed receiver. Many models are capable of blocking the following mechanisms:

1. Farter.

2. The ignition system.

3. Fuel pump.

4. Computer, which manages fuel injection.

Benefits of Immobilizer:

1. It is very difficult to understand that such a device is in the car. Even if the thief carefully examines the vehicle before the hijacking, it will not be able to notice it. But after hacking, he will have a lot of problems.

2. It is actually implicitly connected.

3. It is convenient and easy to use.

4. It is very reliable and works like.

Immobilizer block where to install it

It is necessary to install it as much as possible, sometimes, for this you need to completely remove the front panel. In a similar situation, you will be easier to perform other, necessary work, for example, a connection to the ignition lock or wiring. Also, you will need to drill a small hole in the plastic panel, the electron lock is mounted in it, which adjoins the block. Whatever the immobilizer is invisible and convenient to manage, it should be set it from the bottom or right.

Immobilizer castle that is

The immobilizer lock is directly in the car and checks on the wireless channel that its key is on the spot. In order to prepare an immobilizer lock to use, you need to guarantee the power control electronics. The first contact must be combined with a terminal that constantly provides an immobilizer plus. It is necessary to do this with the help of a fuse, which is dedicated to the 5a and the attached wire. The second and tenth contacts need to provide commutation with a mass of the electrical system. The third contact must be connected to the ignition lock in the position that the onboard multimedia systems can run. The eleventh contact of the immobilizer is responsible for the connection with the terminal contact, which is triggered in the case of opening the door.

Install the immobilizer with your own hands, the course of work is styled

The electrical circuits that are responsible for the functions of the most important components of the vehicle must be connected to the immobilizer lock. To install the immobilizer correctly, it is impossible to create a break of cable lines, otherwise the thieves can determine the installation site of the instrument and can easily eliminate it. The relay of the fuel pump and ignition, as well as the wires that lead to the start, should be connected to controls to controls and carry out them with a central bunch of cables, branches from which, can be created only inside the front panel. When you install an immobilizer, wire connections need to be created using special terminal barns. When applying twists, you significantly increase the risk that the closure will occur, followed by the fire of the car.

Immobilizer, additional protection against hijacking

Despite the fact that immobilizers are quite effective, the installation of such a device is not 100% safe to guarantee security. If the thieves have a high level of qualifications, they can take advantage of some tricks and still carry out the hijacking of your vehicle. In our article, we decided to describe these tricks, however, know that their use in their own dishonest purposes is illegal. There is no need even to remove the immobilizer module and the restoration of the indigenous electrical circuit, since this procedure takes too much time.

The easiest option will be resolved by the issue with a fuel pump, because it comes to it from the front or rear oven lights directly. If the car has a manual transmission, the starter attackers do not touch, due to the fact that such cars are easily triggered with a push. As for the automaton box, they bypass immobilizer, connecting the necessary terminal directly with the battery. With ignition, most often, it falls for a long time, however, some cunning criminals simply connect new wires and relays with regular terminals.

Also, there are a lot of special devices intended for electronic hacking, which can be connected to typical diagnostic connectors. This method is unrealistic to resist, since the probability of achieving a positive result is actually a hundred percent. But, in any case, the preparation of rapid and invisible hijacks requires significant costs, which often exceed fifty thousand dollars. The hijackers of such high levels do not hunt for simple cars, they usually interest them only expensive machines that need to be equipped not only by immobilizer, and and satellite systems against theft and other protective devices.

It is worth saying that the immobilizer has shortcomings. For example, contactless immobilizers work only on batteries, and they are quite often needed. If the batteries do not replace on time, the device will be useless. Also, there is a radio channel, which is attached to scanning. However, the device's radius is minimal, which makes the read code actually unreal.

Based on the above materials, it should be - if you need to provide your machine maximum protection, you should install an immobilizer that can significantly make it difficult to hijack for even well-trained intruders. If you use the immobilizer at the same time, and the alarm, the chances that your car will bearing, will be very small. Installation of an electronic lock, which automatically disclaims the low-current chains, will allow you to absolutely exclude the movement of the car without the knowledge of the car owner. However, if your vehicle is either one of the most frequently hijacked models, or is simply expensive, you must use additional protective devices.
