The Kwikset Kevo bluetooth-enabled deadbolt for the iPhone eliminates the hassle of carrying around keys, because your smartphone is now literally the key. It won’t open if you say “Open Sesame,” but the touch-to-open system is just as easy. All you have to do to open the single cylinder deadbolt is touch the lock with your iPhone. The app runs in the background, so you don’t have to open it when you reach home. You may also create eKeys and send them to friends and family so that they can open the lock with their own iPhone.  If you don’t have or don’t want to use smartphones to open the lock, Kwikset provides you with the Kevo Fob. It’s already preconfigured to open the lock with a touch, so no additional installation is required.
