When a chauffeur attempts to begin the car, the Engine Control Unit (ECU) sends out an electronic signal to the key. The chip in the key receives this signal and reacts with an unique digital code. If the code matches what is kept 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-- the car will stay immobile, even if the physical blade of the key turns the ignition.
