Key fob not working after changing car battery
Remote key fob for my 2012 Mustang stopped working after a replacing dead car battery. Both remote key fobs don't work. I've tried replacing the fob battery and the reprogramming fob sequence. Nothing works.......
Anyone have anything similar happen? I can't figure out which fuse would be linked with the remote key fob receiver ...

If the batteries have those little lines in them I've had trouble with those at times. Also, take the FOB apart, and pull the connectors up a bit for better connection, maybe scuff them up a bit with some fine sandpaper. If that doesn't work, and I'm not sure there is one, but it could a blown fuse. Since neither one works I'm leaning toward a fuse. Good luck.

Fob
they should never change unless you tried to reprogram or battery died or in backwards. Worse case someone swapped it it for some reason. I've redone my keys & fobs a few times
