Release the key blade: Press the release button and gently slide out the metal key blade.
Open the key fob: Use the key blade or a small flathead screwdriver to carefully pry open the key fob casing. Be gentle to avoid breaking any plastic clips.
Remove the old battery: Once the casing is open, you should see the CR2032 battery. Gently pry it out using your fingernail or the flathead screwdriver.
Insert the new battery: Make sure the positive (+) side of the new battery is facing upwards, just like the old one.
