If the car does not acknowledge the special digital signature of the transponder chip inside the key, it will disable the fuel system or the starter, avoiding the vehicle from running.
The Components InvolvedThe Transponder Chip: A small microchip located inside the head of the key or the fob that sends a low-level signal.The Antenna/Receiver: Usually situated around the ignition cylinder, it gets the signal from the key.The Immobilizer System: The software unit that confirms the signal and enables the engine to begin.The Evolution of Automotive Keys
