Step-by-Step Battery Replacement

Opening the Key Fob

To open the key fob, look for the indentation near the key ring attachment. Insert a coin or flathead screwdriver into the indentation and twist. This action will crack open the key fob, giving you access to the battery.

Removing the Old Battery

Once the key fob is open, you can lift the old battery out. You can use your fingers, but if it’s tricky, you can use the flathead screwdriver or even a pen or pencil. Look for a small dark square indentation to help lift the battery.

Inserting the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing down. Click it into place. Once the new battery is in, click the two halves of the key fob back together.

Final Steps

After replacing the battery, your key fob should work like new. This new battery should last for years. By doing it yourself, you save time and money compared to visiting a dealership.
