I've read in a few places I can reprogram my remote by cycling from off to Run 8 times and ending on Run. They locks are then suppposed to cycle to let you know you are in programming mode. Mine, however, do not. Anyone else encounter this or have any ideas? Thanks.
Those are the instructions for the late 98-99+ mustangs. For a 97 here are the instructions:
Turn ignition to RUN or ACC. Momentarily jump pins in programming connector located in left rear quarter panel area. All doors will lock then unlock to confirm programming mode. Press any button on 1st transmitter. Door locks will lock then unlock to confirm programming. Press any button on 2nd transmitter (up to 4 transmitters total possible). The door locks will lock then unlock to confirm programming. Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.
