Ensure you have a replacement battery. Typically, a CR2032 battery is used for Ford key fobs.
Work in a clean, well-lit area to avoid losing small components.

2. Open the Key Fob

Use a flathead screwdriver or coin to gently pry open the key fob along the seam.
Take care to apply even pressure to avoid damaging the clips.

3. Remove the Old Battery

Once the key fob is open, locate the battery compartment.
Carefully remove the old battery, noting its orientation (positive side facing up).

4. Install the New Battery

Insert the new battery into the compartment, ensuring the correct orientation (positive side up).
Press down gently to ensure it is seated correctly in place.

5. Reassemble the Key Fob

Align the two halves of the key fob.
Press them together until you hear a click, ensuring all clips are secured.

6. Test the Key Fob

Stand near the vehicle and test the key fob functions (lock/unlock) to ensure it is operating correctly.
