This chip transmits a passcode from the fob or key to the immobilizer unit of the car, which can be integrated into the PCM (power control module) BCM (brake control module) instrument clusters smart junction boxes or standalone modules. The system then verifies the code to make sure it is correct. If it is not, the system will disable elements that are crucial to the start of the vehicle, like the starter motor or ignition.

Its goal is to prevent the engine from starting when someone else has an identical key. It works by transmitting a radio frequency from the key to the immobiliser system. If the code stored in the car's computer matches that signal from the key, it will deactivate the immobiliser and allow the engine to start.
The key that has a transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. With the help of special techniques, it is feasible to copy a conventional car key however, not the transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder, the ignition cylinder must be in the ON position. The ring emits a burst of IR energy, which is picked up by the microchip within the key. The chip then sends an unique code to the immobiliser inside your car. The computer in the car compares the code stored in its memory to the transponder's and when the two codes match it will begin the engine.
