  • Not to mention the fact that doorknobs break….a retractible doorknob would break just that much more. More parts.

    What I would like is a doorknob that also has a numeric code keypad so if you forget your keys/lock yourself out, you can enter your code and get back in.

    Personally I’d like to do away with door knobs altogether. A bluetooth enabled or voiceprint enabled door would be nice, too.

    They probably exist; I should look around.

  • They have numeric keypads like that. However, they’re mostly for the reverse. You use the combo until you forget, and then the key gets you in.

    Non-door knob doors would just be that much more hackable. I’d rather someone need to break something physically (and possibly be noticed) than something they could hack with a long-distance antenna and a car a block away.

    Oh great blog that illustrates important perspectives regarding the security concerns by having doorknobs installed with the doors, which could make only authenticated people enter in.
