An immobilizer is an electronic security device that prevents a vehicle from being started with an unauthorized key. It works by verifying the unique code or signal from the key fob. If the code is not recognized, the immobilizer blocks certain systems, such as the fuel pump and ignition, preventing the vehicle from starting.
