Every VATS key produced with a unique resistor on the key blade and possesses a possible codes of 1 out of 15 values. By assigning a vats key with the correct resister pellet, the driver inserts the key blade into the ignition lock, which then make a contact with the resister pellet on the key so the electronic VATS system can reads its value. If the key has a match resister pellet, then the car will start, otherwise, then the engine will be disabled.
