Ive had my mustang for about 5 months now and just the other day my keyless entry stopped working. It wouldnt be such a big deal to me but theres a very small dent right on the lock on the drivers side door so i have to unlock it from the passenger side,(its a pain). I already replaced the batteries in the peice and it still doesnt work. Does anyone know how i can get it fixed??

 

I would just buy a cheap replacement off of Ebay and do a search on here on how to program the new remote and you'll be good to go.

 

Try replacing the battery inside the Key FOB(lock/unlock/alarm/trunk switch.)
If not, try reprogramming the key FOB(search for it, it's a simple process) once you have access to the inside of the car again.

And like the guy before me said, you can get a cheap new one on Ebay. They're the same ones Ford gives out

 

thanks guys
