As I expected, my local key guy was able to make me a couple of spares, tested both on the bike, one works fine, the other tends to stick a bit, but with very minor jiggling it works. We lubed the tumbler, and he did quite a bit of fine tuning the second key, but it wouldn't work any better, so we called it good. He thought with use the second key will work smoother, and that also over time, the tumbler will "break in" and will work smoother with that key. 330 miles or so on the bike and I have no idea if anything will break in or get smoother, but I've got 2 spare keys that work, plus my 2 original Alta keys, so I think I'm all set for keys and yeah me and yeah us.
The blanks he used are:

I'll update the first post to get the info to the top so if anyone is searching for this info in the future it will be easier to find. -Ed
