I partially closed the door and locked the car with my remote. I noticed the door was slightly ajar and pushed it shut completely. When I returned, the door will not budge. The electronics work for the locks and windows. The door handle will unlock it from the inside but will not engage the latch. The key will unlock the car from the outside but the exterior handle will not work either. The car has 184,000 miles so the parts could be worn. Any ideas ? Is there a diy for removing the door panel while the door is closed ?
