This is a review of the Lockitron Keyless Entry System. They are now shipping to those who preordered. Several features are still not 100% working. Their "Sense" auto unlock feature is still not available, as well as the notification when someone knocks on the door.
I had many issues with my Kwickset, but once I got it working, it worked like a charm. Still seems more hassle since you have to wake up the Lockitron before doing it. So I can't get home, unlock it from my car, then carry everything in. I have to go up to the door, kick or shake it, then unlock it. Seems more of a hassle.
