The whole system's incredibly effortless to operate. Simply open the app and press "Start Car." That's it. Once your engine's on, you'll receive a "Car Started" notification and you'll be able to lock/unlock your doors as you please. There's also a "Geofence" feature that'll notify you if your car ventures out of pre-programmed parameters, making being a teenager that much more awful.
