Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, multimeter, and a replacement fuse if necessary.
Ensure the vehicle is in park and the ignition is off.

2. Key Fob Inspection

Remove the back cover of the key fob using a flathead screwdriver.
Replace the battery if it appears weak or corroded. Use a CR2032 battery.
Reassemble the key fob and test it to see if the locks respond.

3. Fuse Check

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the power locks (refer to the owner's manual for the exact fuse number).
Remove the fuse using a fuse puller and inspect it for continuity. Replace if blown.
Reinstall the fuse and check the operation of the power locks again.

4. Wiring Inspection

Remove the door panel using a Phillips screwdriver and flathead screwdriver.
Visually inspect the wiring harness connected to the door lock actuator for any visible damage or disconnections.
Reconnect or repair any damaged wiring as necessary.

5. Actuator Testing

Use a multimeter to check the voltage at the door lock actuator connector while pressing the lock/unlock switch.
If voltage is present but the actuator doesn’t work, replace the door lock actuator.
If no voltage is present, trace the wiring back to the switch for further inspection.

6. Switch Verification

With the door panel removed, disconnect the door lock switch connector.
Test the switch using a multimeter to ensure continuity when pressed.
Replace the switch if it is faulty.
