(1/18/2002):  Went out to the car, and tried to unlock it via the power locks, and the drivers side door wouldn't unlock...  So I stuck the key in it, and the whole lock cylinder came out!

Luckily none of the pins or springs fell out...

It didn't look like anything had broken, so I Had a hunch that it just came loose, and the rest of the parts were in the door.  After I took off the doorpanel I found the parts.

I cleaned the mechanism up, lubed it, and put a little locktite on the screw.  Works fine now.

I love the easy fixes!
