Solution

1. Preparation

Gather tools: Screwdriver set, multimeter, replacement fuses (if necessary), and a new key fob battery.
Ensure the vehicle is parked securely and the ignition is off.

2. Inspect Key Fob Battery

Remove the key fob casing using a small screwdriver.
Replace the old battery with a new one (CR2032 or as specified).
Reassemble the fob and test the lock/unlock function.

3. Check Fuses

Locate the fuse box, refer to the vehicle’s manual for the specific location for the central locking system fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity using a multimeter; replace if blown (use the same amperage rating).
Reinsert the fuse and test the locks.

4. Inspect Wiring and Connectors

Remove the door panel using a screwdriver to access the interior components.
Visually inspect the wiring harness and connectors for damage or corrosion.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wiring or connectors as needed.

5. Test the Lock Mechanism

If no issues are found in the key fob, fuses, or wiring, test the lock actuators.
Use a multimeter to check for voltage at the actuator when the lock button is pressed.
If there is no voltage, the body control module may be faulty, requiring further diagnostics or replacement.
