The Lockitron system by Apigy combines an electric deadbolt with a plug server connected via an Ethernet cable. You use your smartphone to communicate with the server controlling the lock over the web (the data is encrypted and avoids potentially dangerous Wi-Fi systems) to open or close the bolt. The Lockitron also has an available NFC option for select phones and accepts physical keys in the event of an emergency. Another interesting feature is the ability to make digital "keys" and send them via email to friends, relatives, or drunken exes.
The initial setup cost runs from $295-$500, so you're definitely going to be investing more than your average Schlage but how else will you be able to open your house like a Jetta? You can find it here.
