lock smiths can do amazing things. I had a cylinder for a lock box, with no key. took it to a locksmith and he figured out what blank was required. then he inserted it into the cylinder, wiggled it sideways a few times, evidently noted on the blank where it was contacting the tumblers or whatever they are, and ground it away. after a half dozen tries he had a key that worked.

Yep, that's called "hand fitting". And it's exactly how the locksmith made a working key for the driver's door lock on my coach when I first got it. Once he had that one working smoothly, he then made duplicates for me by conventional means.
