Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and trim removal tools.
Ensure the vehicle is parked securely with the ignition off.

2. Check Key Fob

Remove the cover of the key fob using a small screwdriver.
Replace the battery with a new one (typically CR2032).
Reassemble the key fob and test the locking function.

Remove the interior door panel using trim removal tools and a screwdriver.
Disconnect the electrical connector from the door lock actuator.
Inspect the actuator for physical damage or corrosion.
If damaged, replace the door lock actuator with a new one.

4. Test Door Lock Switch

Using a multimeter, connect the probes to the terminals of the door lock switch.
Press the switch and check for continuity.
If there is no continuity, the switch needs to be replaced.

5. Check Wiring and Connections

Visually inspect the wiring harness leading to the door lock mechanism for frays or cuts.
