4. Insert the New Battery: Insert the new battery, ensuring the positive (+) and negative (-) sides align correctly with the contacts in the compartment.
5. Close the Key Fob: Carefully close the key fob, ensuring it snaps shut securely. If you used screws, tighten them back into place.

• Use a Key Fob Case: A protective case can help shield your key fob from scratches, dust, and moisture, which can contribute to battery degradation.
