This Kwikset deadbolt door lock has a sensor beneath the lock cylinder, allowing you to program the lock to read fingertips to unlock the door. The door can "learn" 50 people's fingertips. Need a handyman? You can program his fingertip into the lock for one day, and deny him access later. And you can still use a good, old-fashioned key if you prefer.
