How to program your key fob
This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.
Replacement key fobs
Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

1996 Ford Mustang
Remote / key fob programming
This remote can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new remote, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.
Key programming
You can add a new key to this Ford yourself if you already have two keys that start the engine. The new key must be cut first, and it has to be a genuine key — a cloned hardware-store key won't work.
Replacement key fobs
