2. Remove the door panel. To do this, you will need to remove the screws that hold the panel in place. The screws are located around the edges of the panel, and they may be covered by plastic caps.
3. Locate the door lock. The door lock is located on the inside of the door, behind the door handle.
4. Remove the old door lock. To do this, you will need to use the screwdriver to remove the screws that hold the lock in place.
5. Install the new door lock. Insert the new door lock into the door and secure it with the screws that you removed in the previous step.
6. Test the door lock. Make sure that the door lock is working properly by opening and closing the door several times.
7. Reinstall the door panel. Reattach the door panel to the door by replacing the screws that you removed in step 2.
