It can be integrated into the PCM (power control module) BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules.

It functions by sending an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be removed and the engine will be able to start.
The key that is equipped with a transponder chip is often referred to as a 'fob' or a smart key due to the fact that it is more difficult to copy than a traditional mechanical key. With the help of special techniques, it is feasible to duplicate a standard car key, but not transponder keys. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip, the ignition cylinder has to be turned to the ON position. The ring emits a burst IR energy that is received by a microchip within the key. The chip then responds with an unique code to the immobiliser in your car. The car's computer compares the code stored in its memory with that from the transponder chip, and when they match, the engine will start.
The immobiliser will disable the engine if it detects an unauthorised transponder or key. It also stops any vital components of the vehicle from working.

The car immobiliser is a fantastic method of read more deterring thieves, but it can sometimes be out of sync. This could be due to interference or the system becoming too sensitive. This may require a reset. To website do this, disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and begin the car.

The security light is the vehicle immobiliser's way of telling you that there's a problem with the system. If the light is illuminated and you attempt to start your car, it is a sign that the code in the ECU is not compatible with the chip inside the key. This could happen if you have recently replaced the car key with another that isn't programmed to the vehicle, or when you've check here had a damaged swapped ECU.

Modern cars come with this security system in the standard configuration. This makes it difficult to hot-wire a vehicle or use a different key for starter. The system works by analyzing the chip in the key fob or key and sending a passcode back to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system won't allow the car to begin in the event that it does not receive the correct code. Certain models will even notify the owner if they attempt to use a wrong fob or key.
However it isn't completely secure. Some thieves have bypassed the immobiliser by using techniques such as 'hot-wiring.'

This is a risky method and requires a lot of knowledge to avoid electrocuting oneself. In addition, many modern car thieves have switched to more sophisticated methods such as using specialised apps or Bluetooth to steal the car's information and remotely control it using their phone.
