Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and a replacement key fob battery if needed.
Ensure the vehicle is in a safe, well-ventilated area.

2. Key Fob Battery Replacement

Locate the key fob and carefully open it using a small flat-head screwdriver.
Remove the old battery and replace it with a new one, ensuring the positive side is facing the correct direction.
Reassemble the key fob and test the locking mechanism.

3. Inspect Power Lock Switches

Remove the door panel where the power lock switch is located by unscrewing any screws and gently prying off clips.
Disconnect the power lock switch connector.
Use a multimeter to test continuity by pressing the lock/unlock buttons; replace the switch if no continuity is detected.

4. Check Wiring and Connections

Visually inspect the wiring harness connected to the power lock system for fraying, corrosion, or disconnection.
Repair or replace any damaged wiring using appropriate automotive wire and connectors.
Reconnect any loose connections securely.

5. Test and Replace Central Locking Relay

Locate the fuse box and identify the relay associated with the central locking system using the fuse diagram.
Remove the relay and test it with a multimeter for continuity.
Replace with a new relay if it fails the test.
