Step-by-Step Battery Replacement
Step 1: Preparing Your Key Fob
Start by flipping your key fob over to the back. You will notice a plastic section with an indentation in the middle. This is where you will insert your coin.
Step 2: Opening the Key Fob
Insert the coin into the indentation and twist it counterclockwise. Sometimes, the back cover can be a bit stubborn and may look like it isn’t opening. If this happens, use your fingernail or a flathead screwdriver to pry it open gently. Once twisted all the way, the cover should come right off.
Step 3: Removing the Old Battery
With the back cover off, you will see the old CR2025 battery. Carefully pull the battery out of the plastic housing. Dispose of the old battery properly.
Step 4: Inserting the New Battery
Take your new CR2025 battery and ensure that the positive side, marked with a plus sign, is facing down. Place the battery between the three tabs, ensuring it sits securely. Loop the ring around these tabs if it has come off during the process.
Step 5: Reassembling the Key Fob
Now, place the back cover back onto the key fob. Rotate it until it sits securely in place. Use the coin to twist the cover clockwise until it is horizontal again. Your key fob should now be properly reassembled with a fresh battery.
