My car is a late W201. Not sure what the exact similarities and differences are between my lock and the OP's. Sorry if I only provided a source of confusion.

But to add something of minimum substance, I polished out the bezel because I scratched it pretty bad with vice grips trying to get it out. Looks really nice now.

Sorry to take the thread further from the OP's problem. The 201 lock bezel isn't held by clips. There are two retractable flanges built into the lock mechanism. When you insert the tool to remove the cylinder, it also releases the bezel by levering the triggers on the back of the flanges. They can't be permanently removed as far as I can see.

My car had semi-circular clips around the exterior perimeter of the cylindrical part that the tumbler goes into. I had difficulty reinstalling the bezel and I saw them kinda hanging halfway out with the springs that push them into place, so I moved them out of the way and they fell into the dash.

Sorry if that's a bit of word salad but I don't have the correct terminology to explain in a way that would be more understandable without images of what I'm talking about.

Ah. Those would be the flanges. They must have detached from the lock mechanism somehow, otherwise the bezel would just snap into place. I may pull out a spare lock tomorrow and see how they come apart. It's a difficult mechanism to describe, but is there anything left holding the bezel in place?

I'm not really sure, tbh. There was one on top and on bottom. It holds just fine and won't come out unless I put the pins through the tumbler to release it. There is a tiny bit of circular play if I mess with it, but it doesn't move at all when it's installed with the dash trim ring in place.
