Solution

1. Preparation

Tools Required: Flathead screwdriver or coin, replacement battery (CR2032 or specific for your model).
Ensure you are in a well-lit area to see small components clearly.

2. Open the Key Fob

Locate the seam of the key fob where the two halves meet.
Use a flathead screwdriver or a coin to gently pry apart the key fob, starting at the seam. Be careful not to damage the casing.

3. Remove the Old Battery

Once the key fob is open, locate the battery. Take note of the battery orientation (positive and negative sides).
Carefully remove the old battery by pushing it out with your finger or a small tool.

4. Install the New Battery

Take the new battery (ensure it is a CR2032 or the specified type) and insert it into the key fob, matching the orientation noted earlier.
Press down gently until it is securely in place.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together firmly until they snap back into place. Ensure there are no gaps.

6. Test the Key Fob

Stand near the vehicle and test all buttons on the key fob to confirm that it operates correctly.
