Hi all got a small but very annoying problem. Everything was working fine on my focus until last night. For some reason my key fob isnt working with my drivers door? All the other doors are opening and locking just not my drivers door. The door itself seems fine. The windows are working and speakers. Plus if i use the key to lock it all the doors lock. Just not the keyfob. Any ideas? Its a focus 1.8td 2001 mk1.
