Ensure you are in a well-lit area to see small components clearly.

2. Open the Key Fob

Using the small flathead screwdriver, gently insert it into the slot on the side of the key fob.
Twist the screwdriver to pry the key fob open, taking care not to damage the casing.

3. Remove the Old Battery

Locate the battery compartment inside the key fob.
Carefully lift the old battery out using your fingers or the flathead screwdriver if necessary.
Note the orientation of the battery to ensure correct placement of the new battery.

4. Install the New Battery

Place the new battery (CR2032) into the compartment, ensuring it is oriented the same way as the old battery (positive side facing 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 click into place, ensuring no gaps remain.
Test the key fob to confirm proper functioning.
