In order to properly remove the door panel, a door panel removal tool should be used. This particular tool slides in behind the panel, harnesses the clips, and aids in pulling them from the inner door structure. Failing to do so may cause damage to the clips, or even better, the door panel itself may rip where the clips mount-this will create a problem when it comes time to reinstall it. This tool can also be used to gently pry off other door panel components. Be careful- the older the car, the more brittle things are.
