I have seen deadbolt locks for front doors that are locked and
unlocked via an infrared transmitter that fits on a keychain. Has any
company come out with one that is triggered by a card fob in your
pocket, similar to what is available on some of the high-end cars?
It would be great to simply walk up to my front door with all of my
groceries and have my door automatically unlock for me.
