Faulty Remotes. ? Which could explain why one packed up a year or so ago and one still worked until that one went faulty too. ??

I have had VAG's where I have spent ages trying to re-synch remotes without success even though they work ok on an RF tester. I have then bought new remotes and they have programmed straight in.

Are these available separately or just as part of a complete key. ?

SNAP.
