The chip transmits a passcode to the immobilizer unit of the car that can be integrated into the PCM, BCM or instrument cluster, smart junction box or standalone module.

With the help of special techniques, it is feasible to duplicate a standard car key however, not the transponder key. Contrary to the remote central locking element of a standard 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.
