Anyone fixed the door lock on a 200 and have p/ns?

[C1J1Miller@aol.com]

Last 3 or 4 times opening/closing the driver's door with the key, locking
felt kind of rough, like something was loose and rubbing.  Very little
effort, just didn't feel right.  Then, the lock cylinder stopped unlocking
the door.  Passenger door works fine... but if it fails, I'm locked out and
don't look forward to getting in through the ski sack.

I have a bentley, etc. but would appreciate any BTDT advice.  Even better,
I'd like to order the parts to fix it prior to taking the door entirely
apart, as it looks like a bit of labor, and the car wouldn't be very drivable
without a door interior.  Anyone have part numbers for the 200?

Thanks in advance,
