Use a small flathead screwdriver to gently pry open the key fob case.

Ensure the battery is seated properly in the compartment.

4. Reassemble the Key Fob

Align the two halves of the fob and press them together until they click back into place.
Ensure there are no gaps between the halves, indicating a secure closure.
