Hi, Recently bought an 2006 Audi A4 2.0T FSI sLine Special Edition. Great car! It only came with one key. How much am I likely to pay at an Audi dealer for a new one (I have the plastic key and code etc)? I've seen blank ones on eBay for about Â£25 but am wary about buying one off there - how does it work with the remote locking? Cheers, Camus.
