A recent this old house show that I watched showed several new front entry lock types. For example, one was a lock that read your fingerprint but the one that I was interested in was a deadbolt which had a small reset device that allowed you to "teach" the lock to open to a differently cut key and reject the old key. It looked like just what I need to change the front entry lock between tennants on my rental house. I can't seen to locate it on the lock manufacturer sites that this old house lists. (note: I am not looking for an entry set with pushbuttons.)

Does anyone know who makes that reprogrammable (keyed) lock?
