Solution

1. Preparation

Gather tools: Small flathead screwdriver, replacement battery (typically CR2032), and a clean workspace.
Ensure the vehicle is in a safe location and turned off.

2. Open the Key Fob

Locate the seam or slot on the edge of the key fob.
Use the small flathead screwdriver to gently pry open the key fob, starting at the seam and working your way around.
Be cautious to avoid damaging the plastic casing.

3. Replace the Battery

Once the fob is open, carefully remove the old battery, noting the orientation (positive side facing up).
Insert the new battery (CR2032) in the same orientation as the old one.
Ensure the battery is seated properly in the holder.

4. Reassemble the Key Fob

Align the two halves of the key fob.
Firmly press the halves back together until you hear a click, indicating that they are securely closed.
Ensure that there are no gaps between the two halves.

5. Test the Key Fob

Stand near the vehicle and test the key fob functions (lock/unlock, start the engine) to ensure proper operation.
If the key fob works correctly, the issue is resolved. If not, further diagnostics may be required.
