When opening the car from the outside using the key, both the driver's side and passenger side locks feel stiff. I blew some graphite in there but it hasn't helped. Is there a way to take the lock off so as to get better access to lubricate it? Any help appreciated. Thanks.

 

Forgot to mention that it's a 1991 240SE wagon.

 

If I were you I would remoev the door panel and check out the lock assembly's.

 

Yeah, I took the door panel off today and was able to lubricate the locking mechanism better. I was unpleasantly surprised when I saw the door panel was wet from the inside. We've had a lot of rain here in NY this past week so that must've done it. I gotta rig up a plastic shield because it seemed to be missing on this panel.

 

Hey, also just wanted to let you know that i had the same problem as you with the locks feeling stiff. And all i did was take some regualr oil and put it on my key and then use it in both locks and it seems to work very well.
