Lockitron is an ingenious keyless entry system that allows you or anyone you designate to unlock a door via a mobile phone (video). Lockitron fits over a standard deadbolt lock and can be controlled by a companion app or via text message. Lockitron can notify you whenever the door is unlocked or even if someone knocks on the door. Lockitron is available for pre-order, with the first shipment expected in March 2013. Last year we posted about the first generation of Lockitron.
