The chip transmits a code from the fob or key to the immobilizer unit in the car, which could be integrated into the PCM (power control module) or BCM (brake control module), instrument cluster, smart junction boxes, or standalone modules. The system then verifies the code to ensure that it is correct.

Using special techniques, it is possible to duplicate a standard car key however, not the transponder key. In contrast to the central locking element remote of a conventional key which is powered by batteries the transponder chip get more info is powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
