I've got a 2006 307 S, the remote locking seems to have packed in and I'm not sure why, central locking all working as it should, but the key fob appears to be failing, have changed the battery, tried resetting it in the ignition too. It will work Very occasionally (roughly 1 in 100 button pushes) any other ideas? Am I missing something obvious? Driving me mad having to use the key, especially if I just want something out the boot, as there's only a keyhole in drivers door. Any help much appreciated!
