Remove door panel
Start by removing all interior cranks, armrests and any other accessories attached to the inside of the door. Remove all screws and be sure to look for hidden fasteners, such as clips or other apparatus used to hold the accessories to the door panel. These clips may be used in addition to any screws or other types of fasteners.
Using your pry bar or a large screwdriver, pry the door panel carefully away from the door, looking down inside so you can see where the clips are. These hold the panel on. Don't pull too hard or poke the screwdriver into the plastic behind the door panel.
Run your pry bar or screwdriver along the door panel edge on the inside, releasing each clip individually as you go. If you're feeling too much resistance from the door panel, carefully look for more screws or fasteners that may still be attached to the door. These may be hidden from view by small pieces of plastic trim.
Once you've unfastened all the clips, the door panel should lift out away from the door, exposing the interior window for tinting.
