When a driver tries to begin the vehicle, the Engine Control Unit (ECU) sends out an electronic signal to the key. The chip in the key receives 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 begins. If the codes do not match-- or if the chip is missing out on-- the car will remain stable, even if the physical blade of the key turns the ignition.
