[QUOTE="saganaga, post: 224112, member: 5445"] I have solved the issue of why some of my measurements seem off. Measuring cut-to-cut for each of the notches of the four keys I have, then using that number to calculate key depth, I found the depths for most of my keys clustered around a few measurements: 7.0mm, 6.5mm, 6mm, and 5.5mm. Which confused me considering that everything I'm seeing says there's only 3 depth options. Even the Honda rekeying kit I found from the early 1980s had three depths of wafers. I graphed the numbers I was getting, just in case I was missing something, and I saw four clusters form. Then I found this: [ATTACH type="full" alt="Honda_Keys.png"]47679[/ATTACH] The keys appear to be identical between 1982 and 1983, but the depths change. I have a mix of 1982 and 1983 keyings going on - the trunk and the matching lock is a 1983+. While everything else is 1982. Including my ignition (makes sense, since it is a 1982 Goldwing). The rekeying kit I picked up is apparently for a 1983+. Argh! When I was test fitting, I didn't catch the problem due to poor lock tolerances. But when I do this for real, I think I'll do some slight filing on the lock wafers to ensure smooth operation. The 1983+ #2 wafer needs about 0.2mm taken off one end to match the earlier #2, and 0.3mm taken off the other side to match the earlier #3 wafer. The 1983+ #3 wafer needs 0.1mm taken off to match the earlier #4 wafer - problem well within the margin of tolerance for these locks, but I'll take out the file regardless. This should work out. Just a note, but with my small sample size, all my 1982 & earlier locks have a three digit key code. While the only 1983 key I have starts with the letter "A". I'm wondering if that denotes the shift from the 1977 to 1982 keying scheme to the 1983+ keying scheme. [/QUOTE]
