Solution

1. Preparation

Gather tools: small flathead screwdriver or a coin, and the replacement battery (commonly CR2032 for Ford fobs).
Ensure you are in a well-lit area to easily see small parts.

2. Open the Key Fob

Locate the seam on the edge of the key fob.
Use the flathead screwdriver or coin to gently pry open the fob at the seam, taking care not to damage the casing.

3. Remove the Old Battery

Once opened, note the position of the old battery.
Carefully remove the old battery by using your fingers or a non-conductive tool to avoid shorting any connections.

4. Install the New Battery

Insert the new battery into the slot, ensuring the positive (+) side faces the correct direction as indicated by the markings inside the fob.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they click into place.
Ensure there are no gaps, indicating the fob is securely closed.
