When a driver attempts to start the automobile, the Engine Control Unit (ECU) sends out an ask for a code. The transponder sends its unique recognition back to the ECU. If the codes match, the immobilizer is shut off, and the car begins. If the codes do not match, or if the signal is absent, the automobile remains stationary.
