Replacing the battery in a Bolt remote key is a simple task that can be completed in a few minutes. It is important to replace the battery when it is low, as a dead battery will prevent the key from working.
To replace the battery, you will need a new CR2032 battery and a small Phillips head screwdriver. First, use the screwdriver to remove the two screws that hold the back of the key together. Once the screws are removed, carefully pry the back of the key apart. You will see the battery inside the key. Use your fingernail or a small tool to remove the old battery and insert the new battery. Make sure that the positive side of the battery is facing up. Once the new battery is in place, put the back of the key back together and tighten the screws.
