You have to take off the door panel. Here are some instructions...I've done it myself 2-3 times:
1) Remove the sail panel ahead of the side window by snapping it off via force.
2) Remove all screws/snaps. There are 2 screws and one snap. The snap is on the forward side of the door and must be pried off with a small screwdriver. One screw is in the cupholder and one is hidden behind a little circular door on the door handle.
3) Stick a screwdriver under the door panel and, working around from bottom to top, pry up so that the door panel pops off. It's all held on by snaps behind the door panel.
4) Manipulate the door handle through the hole in the door panel
5) You're done
Here's a picture overview:
