There will be little round panel retainers around the door panel. Gently push in the center round pin in the retainers until they stop about a 1/4 inside the retainer. Do not try to pry the center of the retainers out, you will break them. If you push the retainers to far they will fall inside the door and you will have to dig them out. Just put them back together and use them again. The panel should lift off with maybe a screw in the inside door handle or on bottom of the panel.
