keyless entry
So maybe I asked this here before, in which case I regret repeating myself.
A few years ago I rented a house in Japan, and it had an awesome keyless entry system. There was no external lock on the front door at all. On the wall next to the door, there was a simple metal plate covering a plain screen. When you lifted the plate, an electronic (image of a) keypad would appear, always in a different place (so that you couldn't look at fingerprints to figure out what the combination was). When you entered the right code, the door would unlock, and you could slide it open. One neat thing about this system is that the rental agency could give us a code that would work for a week, but not thereafter.
I want to install one of these in my house, but I can't find it, on- or off-line. Anyone have any suggestions?
