When a driver attempts to begin the car, the Engine Control Unit (ECU) sends an electronic signal to the key. The chip in the key gets this signal and reacts with a distinct digital code. If the code matches what is stored in the ECU's memory, the immobilizer is shut down, and the engine starts. If the codes do not match-- or if the chip is missing out on-- the car will remain immobile, even if the physical blade of the key turns the ignition.
