You place the Lockitron over your existing deadbolt, and it connects to your phone. So you can use your phone to lock or unlock the door from anywhere. Best of all, it fits on the inside of the door, so you don’t need to worry about somebody messing with it. Plus this device has Bluetooth; you can simply walk up to the door, and it automatically unlocks.
This sleek re-chargeable battery pack stores enough power to charge most handheld electronics and can charge a typical cell phone several times. The JuiceBar's internal Li-ion battery can be re-charged via USB connection or via the built-in solar panel. This arrangement gives you maximum flexibility while traveling or computing.
