With the screws removed, you will need to pry the panel off of the door using a prybar or flathead screwdriver. I wrapped my screwdriver in electrical tape to keep it from scratching the car.

The bottom and sides of the panel are held on with one type of clip while the top is held on by another. Because of this, you want to start prying it somewhere along the bottom edge of the panel, I chose the lower outside corner.
