When a key is placed into the ignition or brought within proximity of a push-to-start button, the car sends a signal to the transponder chip inside the key. If the distinct code kept in the key matches the code programmed into the Car Key Coding's immobilizer, the engine is permitted to start. If the codes do not match, the fuel system is disabled, and the car remains stationary.
