Gently remove both clips, and then carefully remove the old battery. Take note of the positive and negative sides of the battery so you know which orientation it was in when changing the new battery.
Place the new battery in the same orientation as the old one, and click the metal clips back in place. Firmly press the circuit board back into the casing, and reassemble the key onto it. Turn the key in the ignition to ensure that the new battery is working correctly.
