I was able to get the key to do one last turn by flushing the lock with Tri-Flow and running the jiggly sander on the key for five to ten minutes over a four day period. It finally got one last good turn. At that point you want to remove the tumbler and make haste to your most trusted locksmith for them to try to clean and rebuild it. The original tumblers are NLA. I tried to order one for the 1974 R107. Dealer and Classic center were happy to take my money and then the whole thing got lost in the shuffle. The EPC shows the tumbler PN changes five times but does not state that there are no more to be had. Last supported tumblers are for the 1985 and newer cars, which are all the wrong size for our purpose.
