This chip transmits a code to the car's immobilizer unit which can be integrated into the PCM, BCM, instrument cluster, smart junction box or standalone module. The system then validates the code to make sure it is correct. If the code is not correct it will disable the elements that are crucial to start the car, such as the ignition motor or starter motor.

The key with the transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to duplicate than a mechanical key. It is possible to duplicate a standard key, but not a transponder one. Unlike the remote central locking element of a conventional key that relies on battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst IR energy that is picked up by a microchip in the key. The chip responds by sending a unique code to the immobiliser of your car. The car's computer compares the code stored in its memory to the one from the transponder chip, and If they are compatible, the engine will start.
If the immobiliser detects that an unauthorized transponder or key is in use it will shut down the engine and block any of its vital components from working.
