Door key assembly
 

Hi guys I need your help, recently I can't lock my door using my keys and the central door locks are fine so what I did is open the door panel to check what is the problem and I found out that the culprit is the Door key assembly or something(This is where you insert the key) .I want to know the part number for this.I attached a picture.BTW this is a 93 190e

door lock tumbler
 

The door lock tumbler has to be ordered key coded from the dealership, by VIN number to fit only your car. I cannot view your picture but a common problem with that car is breaking the pin that comes out of the tumbler assembly and goes to turn the lock/latch mechanism.

You're right about that the pin broke that comes out of the tumbler .Can I just buy the pin.Thanks

Ron

Can you buy just the pin?
 

In a word: NOPE!

MB couldn't make any money that way, now could they?;)
