Hey everyone. I'm new to the site.bim having issues programming my key fobs for my car. First, I have a factory working keyless unit in my car. I also bought another unit from the junkyard for testing purposes. I bought 4 key fobs. 2 are original to my car year. 2 are After market key fobs. I do the programming as per the instructions by putting the car in acc mode, then short out two prong wire on module, at this time the locks unlock/lock which means programming mode. Then I press button on remote and nothing happens. When you press a button it's supposed to cycle the locks again but nothing happens with mine. I have tried both sets of key fobs and both have same result. I also switched out the keyless unit with the other one, both results are same. All key fobs have brand new batteries.

My questions are, why won't my key fobs program? What are some troubleshooting things I can try? Am i having some sort of antenna issue? My actuators are good otherwise the locks wouldn't cycle when I short the two prong wire. I need help as I really want this working.

I have always used a different method to program the FOB. Cycle the key on and off (do not start the engine) until the locks lock then unlock. Then hit the lock button repeatedly until the doors lock. Has always worked for me (98 Mountaineer, 02 Mustang). Hope this helps.

Thx for responding. That method doesn't work for mustangs 94-98 . Only way to program with these years is thru the two prong in trunk

Should work. Thats how I programmed my 98 mustang.
