if you check the manual, the option to start your car when the battery is down or near gone, i.e. no longer opening the doors, is to press it against the key sign in the steering colum, old place for keys, this way you be able to start the car, and get to a place with a battery replacement. nice feature, never the less I have a backup in my car just in case.
