    The remote locking/unlocking has stopped working on my sisters 2002 Audi A4, is there anyway of re-synchronising the key-fob with only one key as that is all she has, all the threads seem to suggest you need two keys??

    You need VAG-COM and need to programme the new radio transmitter key code into the Convenience module - 5 min job with the right tools!
    See under Channel 21 in this link.

    you can also resync a key by putting it in the lock in the handle, press & hold unlock while turning the key to unlock, then press & hold lock while turning the key to lock

    i've synced mine this way before when the battery had been disconnected when the engine was being rebuilt.

    This will re-sync the "rolling code" which may be the problem jiffi77 is having and assumes the key has previously been matched to the car and is not totally new.

    Yeah, that's how I read it, that it was the existing key and it'd lost sync
