Just bought myself a B8 2010 S4 and delighted with it - quite a step up from a 1.8T even though it was tuned ......anyway, it only came with one key and wondering what the best bet is for getting a spare.

Looked on ebay and there seems to be a number of used ones and also new key inserts - should I just go to the stealer or what would you guys advise ?
