Door trim
The door trim is held in place by one phillips screw inside the door behind the triangle trim, a pop clip near the top (mine was broken already), and mounting tape. Remove the screw and carefully pull the trim off using a plastic trim tool to pry the trim off from the tape. The pop clip is near the top arrow in the picture below. Careful removing the door trim as the side closest to the edge of the door wraps around the door edge. When removing you'll want to pry up from the front and then slide back and off.

Door lock ring replacement
Once you have the door trim off it's quite obvious how the lock ring rotates and slides in and out of place. Rotate the cam end (or big end) 90 degrees clockwise, then push the opposite end through to the front and the ring will slide out.
