Apologies if this has come up before but I can't find anything that can help me. My remote locking occasionally decides not to work and I have to use the key in the lock instead. However if I then leave the car then come back to it later it will happily unlock using the remote and sometimes it will lock with the remote too. It's definately nothing to do with any doors being open or anything like that, the battery is fine when it does work it works meters away. Im stumped, please help!!!
