How do you replace the battery in the key remote of an Opel Astra? Take your remote control and press the release button of the metal key; use a screwdriver to pry between the key cover and the battery cover. Pry until the cap separates from the key cover; extract the worn battery with a small screwdriver (get a new one of the same size and voltage).

After reassembly, press the cover onto the key case until you hear it click into place. Check the remote's proper functioning by pressing the unlock buttons.
