Programming Your 2012 Mustang Key Fob Remote
This procedure will program the remote control functions of your 2012 Ford Mustang key fob. Please note that this process does not program the transponder chip needed to start the engine.
-
Ensure all doors are closed. Open only the driver’s side door. Press the UNLOCK button located on the driver’s side door panel, keeping the door open. Insert your key into the ignition.
-
Cycle the ignition from OFF to RUN eight times in quick succession (within 10 seconds), concluding in the RUN position on the eighth turn. You will hear the door locks cycle, indicating that the vehicle has entered programming mode.
-
Within 20 seconds of the door locks cycling, press any button on the first keyless remote you wish to program. The door locks will cycle once more to confirm successful programming of this remote.
-
If you have a second keyless remote to program, within 20 seconds of the last lock cycle, press any button on the second remote. Again, the door locks will cycle to confirm programming.
-
Turn the ignition to the OFF position. The door locks will cycle one final time, signaling the end of the key fob programming mode.
Programming the Key Portion of Your 2012 Mustang Key
Programming the PATS (Passive Anti-Theft System) key portion of your 2012 Mustang key requires two already programmed, working keys. If you only have one working key, programming an additional key yourself is not possible using this method.
To program the key portion, follow these steps:
-
Insert an existing, working key into the ignition cylinder.
-
Turn the ignition from OFF to RUN and then back to OFF.
-
Remove the first working key and, within five seconds, insert a second working key. Turn the ignition to RUN and then back to OFF.
-
Remove the second working key. Immediately, before ten seconds elapse, insert the new, unprogrammed key into the ignition and turn it to the RUN position. Keep it in the RUN position for one second, then turn back to OFF.
-
The security light on your dashboard will illuminate for three seconds to indicate that the new key has been successfully programmed to start your 2012 Ford Mustang.
If you only possess one working key, you will need assistance from a qualified automotive locksmith to program a new key. Locksmiths possess specialized diagnostic equipment to program Ford keys. Alternatively, you can purchase a key programmer designed for Ford vehicles to perform this task yourself.
