The battery has gone in my Astravan Keyfob, does anyone know how to change the battery without wrecking the fob - please? Also what do I need to do with regards to the code etc when the battery is replaced?
According to the handbook you have 3 minutes in which to change the battery without having to "resynchronise" the key.
This is done by switching on the ignition and pressing either button on the key fob within 30 seconds.......the central locking will lock and unlock to show that you've been successful.
