last month the driver's door on Mellow Yellow decided to stop locking.
Key would not turn, button would not depress. I posted a general
question about this problem here, and Professor Bell provided some handy
hints for disassembly and inspection. Bentley's, as usual, gives useful
help, too.

My son works in town at the local lock and safe shop and works on car
doors all the time. He came over today and we took apart the door and
pulled the latch . . . and found no problem. There were no issues found
external to the latch assembly, and the inside of the mechanism didn't
show any signs of trouble, either. Nothing was visibly out of place or
broken. Everything moved as it should without any great resistance.

It was a bit gummy inside, a little old black gunk, so we cleaned it
with mineral spirits and a flux brush, applied silicone lubricant
liberally, and assembly -- as they say -- was the reverse of disassembly.

Door lock works fine. No problem found. It baffles science.
