Ford, the world's second-largest car manufacturer, offers a keyless entry system called MyKey. Ford MyKey is designed to help car owners protect their security by limiting specific driving capabilities. Whether or not disconnecting the battery in your car reset Ford MyKey depends on the age of your key fob and the type of car you have. If your car was made after 2012, this should work just fine; but if it was manufactured before 2008, it won't due to the lack of an immobilizer system that can detect engine functions like fuel injection or ignition.
If your vehicle is equipped with an immobilizer system that detects fuel injection or ignition, disconnecting the battery will not reset the Ford MyKey and disable your voiture's engine function. Meanwhile, if your MyKey system doesn't rely on engine function, disconnecting the battery will reset it, and you can use your key fob again.
