remove all trim off the door like winder handle, grip handle and door opening handle trim. peek between the door card and door frame to locate the several push-on clips, slip a flat head screwdriver next to the clips (only between the door frame and the plastic lip of the clip, not the hardwood board otherwise you'll be forcing the clip off the hardwood board and wrecking it) and pry the plastic clips off the door frame.
