Might also be worth a look under the left fairing pocket. A number of people have found that a spare key for the bike was in there possibly from the factory or the dealer. One of my 1200's had a pouch in there like others had described, stuck to the side, inside that pocket hole, but it had fuses in it so the PO had likely removed the key that was originally there.
Other than that, some locksmiths have the ability to make factory keys as well, from the number. I had one made for my 86 Aspy because the keys I had were so badly worn, I didn't want replacements made from them. You will likely have to prove ownership to get them made though.
