How to Troubleshoot a Camper-Shell Lock

A camper shell is a large camper that attaches to the bed of a pickup truck and is secured via door locks. When a camper-shell lock goes on the fritz, frustrations mount. Troubleshoot and get the lock back to working order with some simple hand tools and dry lubricant. Use a dry, graphite-based lube to prevent excess gunk from developing in the tiny lock mechanisms.

      Insert the key into the keyhole. Turn and try to open the lock. Listen for grinding or gritty sounds.

      Slide the slim-jim between the door jamb and the lock stopper to force open the door lock.

    • 3

      Unscrew the lock unit on the side of the door and pull it out 1/2 to 1 inch. Squirt lubricant into the lock gears, tumblers and stopper. Push the stopper with your fingers to move the lock manually.

      Insert the key into the hole and turn. If the lock still doesn't turn, squirt lube into the keyhole.

    • 5

      Insert the key and try turning it again. Once the lock turns, screw the unit back into the door and roll on down the highway with a functioning lock.
