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 will check the code to make sure it's correct. If the code isn't correct it will disable the elements that are crucial to start the car, like the starter motor or ignition.

The system works by sending a passcode from the key fob to the ECU. The ECU is aware that it's the right key and that there hasn't been compromised code. The system won't allow the car to begin if it does not receive the correct code. Some models even notify the owner when they attempt to use a wrong fob or key.

This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking that the proper key or fob is being used. This is a risky technique and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods, like Bluetooth or other specialized apps to take over a car's data and remotely control it.
