Solution

1. Preparation

Gather necessary tools: small flat-head screwdriver, new key fob battery (typically CR2032), multimeter.
Ensure you are in a well-lit area and have a clean workspace.

2. Open the Key Fob

Use a small flat-head screwdriver to carefully pry open the key fob casing along the seam.
Take care not to damage the casing or internal components.

3. Replace the Battery

Identify the battery type and remove the old battery from the key fob compartment.
Insert the new battery, ensuring correct polarity (observe + and - symbols).
Reassemble the key fob casing by pressing it back together until it clicks securely.

4. Reprogram the Key Fob (if necessary)

Sit inside the vehicle with all doors closed.
Insert the key into the ignition and turn it to the "On" position without starting the engine.
Within 10 seconds, press the lock button on the key fob 5 times.
Turn the ignition back to "Off" and remove the key.
Test the key fob functionality.

5. Verify Central Locking System (if issues persist)

If the key fob still does not respond, inspect the vehicle’s central locking system for issues (e.g., blown fuses, damaged wiring).
Use a multimeter to check for power at the central locking actuator.
