Here's a quick demonstration of the Kevo smart lock by UniKey. You can order yours on Amazon for $219: http://goo.gl/luCDxT Took about 20 minutes to install and few more minutes to calibrate my iOS devices. Works great! I hope to make some a few more videos once I have some more free time.
Kevo is only for iOS devices that support bluetooth 4.0 low energy (starting with 2011 models as early as iPhone 4s and up). I read UniKey will develop an Android app as soon as Google provides the required API's for developers that fully take advantage of bluetooth 4.0 low energy. Don't be disappointed if you have a android, windows or blackberry phone since you can use the included key fob in the mean time.
Let me know if you have any questions!
