How to Change the Key Fob Battery on an Opel Corsa

Model: Vauxhall Corsa Corsa C - Years 2000-2006
Part: Key

How do you change the key fob battery on an Opel Corsa? Take your key fob, and use a screwdriver to pry the cover away from the rest of the fob (as shown in the video), then lever between the two parts of the plastic key cover. Keep prying until the cover opens. Remove the plastic body and open it by hand, take out the worn battery with a screwdriver, and get a new one of the same size and voltage. Reassemble the cover on your fob by pressing on the key cover until you hear it click into place. Check that it works correctly.
