Today I tore into my non-functioning driver door lock. I followed the great instructions here-


One tip not found there is if your lock leaves are old and worn, i.e. they stick out when the key is in, you can remove the broken leaves and put the cylinder back in.

I removed three leaves that stopped the lock from turning with the key. I saved them and plan to bring it to a locksmith for repair later, but this is a good working tip!

Yep ... mine looked like it was recovered during an archeological dig. I disassembled, scrubbed in carb cleaner and sanded corrosion off the leaves. I was able to put all the leaves back in and they worked fine ... I wouldn't leave them out because that kind of raises the chances that anyone else's key will work in your lock. Guess it's not a big danger temporarily though. Once I got all the leaves back together, then the flap came off the keyhole, and I had to reassemble that through the keyhole, what a trick that was. Works now, though. No puzzle why it wouldn't turn:

Fixed:

You weren't lying, that was a dig! Mine looked like you could eat off it compared to that! Nice job!
