No need to bother carrying around a ring of keys like some medieval dungeon master, metal keys are now a thing of the past. Lockitron allows users to lock or unlock the door to their home with their smartphone from anywhere in the world. The technology also notifies you when there's a visitor at your door and allows you to grant lock access to as may people as you choose.
