A new door lock turns smartphones into keys, ditching the hassles of keys, codes and sharing access to your house, apartment or business with Bluetooth, WiFi and apps.

The Lockitron is an adapter that mounts on existing deadbolts to transform almost any lock into a smart connected lock, controlled by an iPhone, Android or other phone.

Lockitron is not a lock, so renters and even the least DIY inclined individuals can install it over an existing lock. The system allows users to unlock their home with an app, share access with house guest without lending a key and much more.
