Remove the integrated key from the remote control. There is a small square on the key; press the square to remove the key. Place the integrated key under the battery compartment cover and use the lever action of the key to lift the cover. Find a sharp object and press along the direction of the battery to pry it out. Remove the old battery and insert the new one with the positive side facing up. Finally, reinstall the battery compartment cover to complete the replacement.
