I found a partial solution to the no red key/extra key problem (don't ask) for my 2002 S4 and I thought I would pass on the info. On a lark I obtained a Silica (made in Italy) # KW17T5 blank and had a local locksmith with a cloning machine program and cut the blank to match my existing black key. I have no idea if the new (or original black key) will work for anything other than starting the bike that is why I said partial solution. This won't help you thiefs out there because you will still need an original key to copy the code from. In any event the new key works like a champ and I feel a lot better having a spare.
