Well it turns out that the dealer is, how shall be put it nicely... Inept. We met up in Asheville and the entire process took perhaps 10 minutes. Probably could have done it faster but we talked a bit. Also, and this is key, we tested all 3 keys before labeling the process a success.
Why is this so hard for "service professionals"? I really don't know. I learned how to run the KDS3 system the old-fashioned way. Reading the manual. I must conclude that many service "techs" at dealers are illiterate.
Anyway, it was good to meet a fellow C14 owner face-to-face.
