Got Wilton's package yesterday with 2 replacement door handles and locks, thank you sir!
Turns out the lock tumblers basically fall out of the cylinder when everything isn't all jammed up. So I cut my old driver's side cylinder apart (finished cutting anyway, I'd started last week. Cleaned each tumbler good with a wire wheel and 400 grit sandpaper.
Interestingly my tumblers didn't fit in Wilton's cylinder the same as they fit in mine, odd... I had to use a mixture of his and mine to make it work. Never the less we got there.
So based on what I now know I realized the lock I'd already "freed up" was only set to fail again. So I took it apart once more and freed ALL the tumblers rather than just the 6 that came easily. Then took them out and cleaned 'em real good. I don't know what MB used in these for lube but its yellow and grease like and mine had picked up lots of dirt and turned into concrete. I sanded the cylinder and tumblers with 600grit to make it all work perfectly smooth and then lubed with graphite from a spray can (its in some kind of carrier).
So the locks are DONE. The doors still need to be buttoned up, they need moisture barriers too. I want to hold off on the drivers door as I haven't tested for vacuum leaks there yet. I already did the passenger's side.
Out of time though, gotta go to a barbeque.
