Solution

1. Preparation

Gather necessary tools: multimeter, flathead screwdriver, and a replacement key fob battery (CR2032).
Ensure the vehicle is in a safe, well-lit area.

2. Key Fob Battery Replacement

Use a flathead screwdriver to gently pry open the key fob.
Remove the old battery and insert the new battery (ensure correct polarity).
Snap the key fob back together securely.

3. Reprogram Key Fob

Sit in the driver’s seat with all doors closed.
Insert the key into the ignition and turn it to the "ON" position (do not start the engine).
Press and hold the "lock" button on the key fob for approximately 5-10 seconds.
Turn the ignition back to the "OFF" position and remove the key.
Test the key fob to see if the unlocking function is restored.

4. Inspect and Replace Fuse (if necessary)

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to the central locking system (refer to the owner's manual for the specific fuse).
Pull the fuse out using fuse pullers or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reassemble the fuse box and test the key fob again.
