My remote gradually stopped working and I have tried replacing the battery, as well as re-programming it to the car as per the owners manual. I want to know if Ford remotes fail very often or is the fault more likely with the car ? I can't see anything physically wrong with it, although I wander if it might have got a little wet the other day. I guess the only thing is to try a new one ! The car is under warranty for another month or so thankfully ! it's a 02 focus tdci.
