I bought a used XT660R (2009) from the auction, and it only had one black key with it, no red key at all. When I found this out I started to panic, but went to locksmith with the one black key I had. He put it in a machine, then copied a chip and put it in a new blank, presto, it worked. Cost me $150.00, but cheaper than replacing everything. At least I have a spare now.
