Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a new fuse (if necessary).
Disconnect the battery before starting work on electrical components.

2. Check Key Fob Battery

Open the key fob and replace the battery if it is weak or dead.
Test the new battery by attempting to lock/unlock the doors.

3. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power door lock fuse (refer to the owner's manual for the specific location).
Remove the fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with an identical fuse rated for the same amperage.

4. Test Power Door Lock Switch

Remove the trim panel covering the door lock switch.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity across the switch terminals when pressed.
If the switch is faulty, replace it with a new switch.

5. Inspect Wiring and Connectors

Visually inspect wiring harnesses for wear, corrosion, or disconnection.
Repair any damaged wires or connectors as needed.
Check the ground connections associated with the power lock system.

6. Check Door Lock Actuators

If all previous steps check out, remove the door panels to access the lock actuators.
Test each actuator by connecting them directly to a power source to see if they operate.
Replace any faulty actuators.
