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 unique code kept in the key matches the code configured into the car’s immobilizer, the engine is allowed to begin. If the codes do not match, the fuel system is disabled, and the car stays fixed.
