Learn to program the remote to your Ford Mustang without any help from the dealer. This includes the Mustang GT model, if applicable for the year.
The Ford Mustang has been redesigned numerous times. Starting in 1994, it became more common to see a remote keyless entry equipped with the Mustang. This remote fob was instantly programmable by following a simple procedure listed out in the factory service manual. Ford dealers can also program the Mustang key or remote for you, but the process may be costly.
