Solution

1. Preparation

Gather the necessary tools:
- Torx screwdriver set
- Multimeter
- Trim removal tool
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Key Fob Battery

Remove the key fob cover using a small flathead screwdriver.
Replace the existing battery (CR2032) with a new one, ensuring proper orientation.
Reassemble the key fob cover.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the trunk.
Refer to the fuse diagram to identify the door lock fuse.
Use a multimeter to test the fuse; replace it if it is blown with a fuse of the same amperage.

4. Remove Door Panel

Use a trim removal tool to carefully detach the door panel clips.
Unscrew any Torx screws securing the door panel.
Gently pull the door panel away from the door, being cautious of wiring harnesses connected to the panel.

5. Inspect Door Lock Actuator

Locate the door lock actuator inside the door.
Use a multimeter to test the actuator for proper voltage when the lock/unlock command is given.
If the actuator is faulty, disconnect it and replace it with a new actuator.

6. Reassemble Door Panel

Reconnect any wiring harnesses to the door panel.
Align the door panel back onto the door and press it into place to secure the clips.
Reinstall any screws removed during disassembly.

7. Final Testing

Test the door locks using the key fob, interior switch, and Tesla app to ensure proper functionality.
