Locate the small slot or notch on the side of your key fob. This is usually near the key ring.
Carefully insert the flathead screwdriver into the slot and gently twist. This should release the back cover of the key fob. Don’t force it; excessive pressure could damage the key fob.
Remove the back cover. Once released, the cover should pop off easily, revealing the battery.
Identify the old battery. It will be a small, round, silver disc (CR2025).
Carefully pry the old battery out using your screwdriver. Again, avoid using excessive force.
Insert the new CR2025 battery, making sure the positive (+) side is facing up. This is usually indicated on the battery itself.
