How to Change Car Locks

Changing car locks must be done when the tumblers inside the lock jam or seize. Unfortunately, this is a common occurrence on older vehicles. But, it does not usually happen suddenly. The main symptom of a failing lock is hard locking (hard to turn the key when locking and unlocking). When you notice this happening on your vehicle, change the lock right away before the lock completely jams.

Things You'll Need

• New car door lock
• Screwdriver
• Trim removal tool
• Pliers

Instructions

1. Remove any trim coverings using a trim removal tool. Wedge the tip of the trim removal tool underneath the trim covering and pry it off the door panel.

2. Remove any bolts underneath the trim covers.

3. Remove the door panel. Pry the door panel off the door frame using a trim removal tool.

4. Remove latch cover by prying up on it with a trim removal tool.

5. Pull the cotter pin out of the bracket that connects the latch bar to the the handle actuator using a pair of pliers. Move the latch bar off to one side.

6. Remove the bolts that hold the door handle to the frame and slide the lock assembly off the frame.

7. Install the new lock. Installation is the reverse of removal.
