Solution

1. Preparation

Gather necessary tools: small flathead screwdriver or a key fob opening tool.
Ensure you are working in a clean area to avoid losing small components.

2. Open the Key Fob

Use the small flathead screwdriver to gently pry open the key fob casing. Insert the screwdriver into the seam and twist carefully to avoid damaging the plastic.
Once you create an opening, work your way around the fob until it separates into two halves.

3. Remove the Old Battery

Locate the battery inside the key fob. It is typically a CR2032 coin cell battery.
Note the orientation of the battery (positive and negative sides).
Use the screwdriver to carefully pop the battery out of its holder.

4. Install the New Battery

Insert the new CR2032 battery into the holder, ensuring the positive (+) side is facing up as per the original orientation.
Press down gently until the battery clicks into place.

5. Reassemble the Key Fob

Align the two halves of the fob and press them together until they snap back into place.
Ensure there are no gaps or loose sections in the casing.

6. Test the Key Fob

Stand near the vehicle and press the buttons on the key fob to check its functionality. Confirm that the doors lock and unlock as expected.
