Cars get broken into all the time. Fixing a car that's been broken into can be a inconvenient, but having someone fix it for you can be expensive. Fortunately, replacing a broken door lock isn't the most difficult thing to do, it should take about an hour of time. In this example, the vehicle is a 2004 Chevrolet Silverado, but the process is similar for most vehicles.
Use the flathead screwdriver the remove the door lock surround and the surround on the interior door handle.
Unbolt the bolts exposed by removing the surrounds using the 1/4-inch ratchet and sockets.
Unbolt the remaining bolts on the door panel along the bottom of the door using the 1/4-inch ratchet and socket set.
Remove the plastic panel that sits next to the rearview mirror using your hands. It's held in place with clips.
Lift the door panel up from the bottom about one inch and pull the panel off the door. The panel is secured by hooks, not clips, so it can be easily removed.
Remove the rubber grommet in the doorjamb on the door panel using the flathead screwdriver. This will reveal one of the bolts that holds in the door handle.
Unbolt the door handle using the 1/4-inch ratchet and sockets and open-end wrench. Three bolts hold the handle: one underneath the grommet you just removed, one on the top of the panel that can only be accessed with a wrench and another that can be accessed with the ratchet.
Unclip the door handle from the latch linkage using your hands. There are two clips that secure the linkage to the handle. They can be removed by pulling back the clip using your hands.
Remove the clip that secures the door lock to the handle. It can be pried off with a flathead screwdriver.
Install the new door lock by placing it in the door handle hole and pressing the clip in place.
Reinstallation is the reverse order of disassembly.
