A:Answer That depends on your proximity to the door. If you are right outside (i.e. in Bluetooth range), you can.
However, in order to unlock it or lock it from, say your office, you will need the Schage Wi-Fi Adapter Model #BR400. It was released in Mid-July but Best Buy does not carry it yet. It runs about $70 and can be ordered from several other retailers.
I've had mine since August and it works fantastically with the lock!
