Solution

1. Preparation

Gather necessary tools: flathead screwdriver or coin, and a new CR2032 battery.
Ensure you are working in a well-lit area.

2. Open the Key Fob

Locate the seam of the key fob where the two halves meet.
Insert a flathead screwdriver or a coin into the seam and gently twist to pry the fob open, starting at one end and working your way around.
Be cautious to avoid damaging the plastic casing.

3. Remove the Old Battery

Once opened, locate the battery compartment.
Note the orientation of the battery (positive side up).
Carefully remove the old battery using your fingers or a plastic tool to prevent short-circuiting.

4. Install the New Battery

Place the new CR2032 battery into the compartment, ensuring it is oriented the same way as the old battery (positive side up).
Press down gently until the battery is securely in place.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they snap back into place.
Ensure there are no gaps indicating that the fob is not fully closed.

6. Test the Key Fob

Stand within a reasonable distance from the vehicle and test all functions of the key fob (lock, unlock, panic button).
Confirm that the key fob is functioning properly.
