Using this key shell is a breeze. Just snap it over your Subaru key, and you're good to go. As for the range issue, don't be too worried. Sometimes it might get a bit reduced, but it's usually not a big deal. When it comes to maintenance, a soft, dry cloth can be used to wipe it clean. Avoid using harsh chemicals as they may damage the carbon fiber and the gloss finish. Store it in a cool, dry place when not in use. Have fun showing off your fancy key!
