Modern automobile security relies on a system usually called a transponder system. "Transponder" is a portmanteau of "transmitter" and "responder." Inside the plastic head of a car key or within a keyless entry fob is a small microchip.
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 responds with a distinct digital code. If the code matches what is saved in the ECU's memory, the immobilizer is deactivated, 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.
