It can be integrated into the PCM (power control module), BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules. The system examines the code to ensure that it is correct. If the code is not correct the system will disable elements that are crucial to starting the car, such as the ignition motor or starter motor.

Also referred to as a 'chip key or a 'transmitter and responder key, it is created to stop the engine from starting if a third party has the same key. It works by sending a radio frequency from the key to the immobiliser system. If the code on the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to begin.
The key that has a transponder is also referred to as a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. It is possible to duplicate a standard key but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a burst of IR energy that is detected by the microchip in the key. The chip then sends an unique code to the immobiliser in your car. The car's computer checks the code in its memory with that from the transponder chip, and If they are compatible the engine will begin to rev.
The immobiliser will disable the engine when it detects an unauthorised transponder or key. It also stops all vital parts of the car from functioning.

If you attempt to start the car but the light is solid on it indicates that the chip inside your key isn't in sync with the code stored in the ECU. This could happen if have recently replaced your car key with another that was not programmed to the vehicle, or when you've had a damaged swapped ECU.

Some models even inform the owner when they attempt to use a wrong fob or key.
However it isn't impervious to theft. Some thieves have gotten around the immobiliser with techniques such as 'hot wiring.'

But, this technique is extremely risky and requires a great deal of knowledge of how to do it without cutting yourself. Plus, a lot of modern car thieves have switched to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's data and then remotely control it via their phones.
