- Locate the battery compartment: This is usually on the back of the key fob. You might see a small slot or indentation.
- Open the key fob: Insert the flat-head screwdriver into the slot and gently pry open the casing. Be careful not to use excessive force, which could damage the key fob.
- Remove the old battery: Gently pry out the old battery with your screwdriver or fingernail. Pay attention to the battery’s orientation for proper replacement.
- Insert the new battery: Place the new battery in the compartment with the positive (+) side facing up, following the orientation of the old battery.
