On the subject of keys and locks, I learned something new last night.
Herb, Kyle and myself tore apart several bus door handles and keyed the door locks from a 68 double cab to use the same key as the ignition. As you may know, 1968 Bus door handles are one year only. They are a little harder to get the tumbers out of the lock (has a clip ring and set screw that newer handles don't have), and the tumblers are slightly different from 69 and later handles. The principle of the lock is the same and the pins are identical to later bus locks. So, for a 68 bus, you have to use 68 handles and tumblers, but you can get your spare pins from any bay window bus.
Also, locking engine lids from later buses have a unique tumbler, but use the same pins. The problem we ran into is the only tumbler we had for this lock would not accept the profile of the key we wanted to use. I believe that if you pull the cap off of the tumbler (it's crimped on) and use a small file on the existing notches in the end of the tumbler, that problem will be cured too. But it was late so we left it for another day.
Oh, and one other thing I forgot to mention . . . some bay window bus handles have a tiny set screw that holds the tumbler in place. If you get it to the point it looks like it should fall out and it still won't budge, check for a set screw. A couple of them had some blue paint over them (I guess that was for warranty purposes so the dealer could tell if the lock had been messed with).
Anyway, it was interesting and I learned a little more about VW locks and keys. If anyone has any door handles they want to re-key, I'll be glad to help.
