If you are having trouble because your truck door won’t open from the inside or outside, there is most likely an issue with rods that hold the lock in place. These parts run between the key tumbler, the door lock button, the lock mechanism, the interior and exterior door handles, and the release mechanism for the latch. These rods keep the door locked, but they can cause problems when they slip out of place.
An easy way to solve this problem is to prevent the rods from slipping. You can do this by threading a lock nut (available at most hardware stores) onto the threaded rod to act as a bumper. Then, clip the threaded rod back into the appropriate clip and secure it there with a plastic zip tie.
There may be a break in the linkage. To check, take off your door panel. Pull on the door handle to see how the mechanism works. The linkage is usually a plastic clip that attaches to a metal piece. You should be able to tell if there is a linkage problem.
The problem may also be with the inside door handle. Take the window switch panel off, remove the screws, and pull out the door panel. Replace the old door handle with a new one. Check with your car manufacturer for a replacement door handle. You can also look online for a better deal.
The cable for your car door may have snapped. To replace the cable, you will have to first remove the actuator, which is connected to the cable. Then, remove the plastic cover to reveal two cables. Replace the broken one with a new one. Cables can also be purchased from your car manufacturer or online.
