When a chauffeur attempts to begin the automobile, the Engine Control Unit (ECU) sends out an electronic signal to the key. The chip in the key receives this signal and responds with a special digital code. If the code matches what is stored in the ECU's memory, the immobilizer is shut off, and the engine starts. If the codes do not match-- or if the chip is missing out on-- the car will stay stable, even if the physical blade of the key turns the ignition.
