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