One of my remote controls has stopped working... Tried recharging it by driving as outlined in previous threads, but no joy, so I changed the battery as detailed in a previous thread and then tried to synch. the key fob, but still no joy:frown. Any ideas what next, does it have to be reprogrammed another way (i.e. dealer programming?:confused). Still unlocks and starts the car etc, just frustrating if I use this key to wake the neighbours at 5:30 am!!! Thanks in advance and sorry if this has already been covered elsewhere.
