When a chauffeur tries to start the automobile, 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 saved in the ECU's memory, the immobilizer is shut off, and the engine begins. If the codes do not match-- or if the chip is missing out on-- the Car Key Programming Near Me will stay stable, even if the physical blade of the key turns the ignition.
