key in the down position-locked. key in horizonal position-follows
lead of vacuum door locks. key in up (ccu) position-unlock. keep
playing. cycle through the door locks several times. when you get it open, file smooth any nicks or rough spots on the mechanism.

sunroof- take off the cover at the hand crank. underneath is a smaller cover over a bolt, tighten the bolt.

Also there were originally two keys to an MB, one is the 'valet' key and does not work the trunk or glove box. Be sure you are using the correct one. Of course if you are attempting to use the one that came with the new lock, it should work fine?!?
