Just about to take possession of a an A4 2.0 TDI S-line (06 plate), but car is supplied with just one key. I need an extra key as the I sometimes swap cars with the wife and she needs a spare key.

I'm sure there has been threads on this before, but I can't find any recent ones (or the old ones). Please forgive me, but I have spent hours looking for the answer to this question.

I suppose I could just go to a main dealer and spend a fortune (150+) but that's what this forum is here for.

I know there are key/fobs available on ebay and programming advice via the net etc.. but some experienced advice would be appreciated.

Kind regards
