That's not quite correct. I know at least opening the frunk and trunk works, as well as unlocking the car. The climate features don't, but haven't tried the others (like flashing lights, horn, venting windows, etc).Your phone will still work as a key to get in the door, and to start the car. But none of the other features of the phone app will work without cell/wifi connectivity.
