How to disable the immobilizer, should know everyone should know motorist

A situation May arise when, in order to start the engine of the machine, you must disable the immobilizer. Some motorists this can cause some problems. In this case it is necessary to know how to disable the immobilizer. Sometimes it is simply necessary because there is no way, for example, to program the keys directly at the device. However, it is understood that after disabling the Immobiliser, your car will become more affordable for all sorts of hijackers. That is why it is necessary to equip a very good burglar alarm. Preferably, if it is to have feedback. In order to understand the principle of operation of this device, it is sometimes necessary to read more than one article.

So, how to bypass the immobilizer? Almost always have it turned off by influencing the engine control unit (ECU Immobiliser). In most cases, the question of how to disable the immobilizer, the answer can be only one – to cut the wire from the device that goes to the engine ECU. This off mainly contributes to the volatile memory of the engine control unit some of the changes responsible for the operation of the immobilizer unit. Such changes may not affect the functionality of the vehicle as a whole, but only in the firmware of the ECU survey immobilizer.

Sometimes in order to avoid the question of how to disable the immobilizer, you need to set to the engine control unit special electronic device.It can be both the emulator and the revision of the existing car circuits. Almost always, such a device is carried out in a circuit Board that has the microprocessor and other electronic components. However, there may arise a situation where on some cars disabling this device is simply impossible, because it can affect the correct operation of not only the engine but also other systems in the ECU. In this situation, can only help to repair immobilizer or replacement and subsequent reprogramming of the keys to stay in sync with the ECU.

All manufacturers on the question of how to disable the immobilizer, the answer is clear – not recommend it at all to do. Many drivers with them will probably agree. A more correct way out of this situation – this programming of car keys. But in very many cases, for example when the controller can be compared in value with the third part of the price of the whole vehicle, the only reasonable solution can only be off.

The number of problems with the immobilizer, this output is the most acceptable. This can be attributed to cars, released in late-mid-90-ies. Here very often there can be some problems with the antenna of the immobilizer. It could be trouble with the wiring, leading to a complete loss of sync ECU or to the loss of the device keys. In the case of continuous occurrence of similar problems and because of the high cost and the inability to replace the whole ECU, it should completely disable the device. In any case, should this task be entrusted to professionals. Only then can we be fully confident that this procedure will be done efficiently and correctly.
