1. Open the key fob: Locate a small button or notch on the key fob, usually on the side or back. Use the flat tool to gently pry open the key fob. Be careful not to scratch or damage the casing.
2. Remove the old battery: Once open, you’ll see the old battery in a small compartment. Use the flat tool or your fingernail to carefully remove the old battery. Note the battery’s orientation for correct replacement.
