TWIST & SHOUT (about forgetting the code!)

Yet another “twist” on something we twist everyday. Designer Jess Han has re-imagined the simple door handle with a DaVinci Code style lock that denies entry for all but the chosen few (cue: dramatic music). This intuitive door handle dubbed the “NUMLOCK HANDLE” features a numbered dial-lock that re-shuffles and locks itself after every successful entry. Get the code incorrect and Tom Hanks gets punched in the gut by an albino assassin.  The numbers can be replaced or supplemented with braille for that extra level of mystery.

Designer: Jaeseok Han

  • Manuel says:

    Great idea!!
    love it!

  • Jeremiah says:

    Neat idea, but there should be some sort of key… Just in case the person forgets their code, or incase of imergency. And I would llike to see the mechanics behind it, just curious. But a sweet idea none the less.

  • Jads says:

    Where can i buy this

  • Ahmet Bektes says:

    Great Idea!
    It is pure and functional.

  • Joe says:

    Video or it didn’t happen.

  • Will Ayers says:

    Really not worth it. I would rather have a key to open the door. I think it needs a better design.

  • Philip says:


    I love this design. It’s simple and fabulous~!

  • Blah says:

    I simply install the camera and record the key.

    It is easy but not functional

  • Such a great piece of design – I want these for our offices… not that we’re very secretive – I just love the minimalist design.

  • David Kaspar says:

    Oh noes, that’s the code to my suit case!

  • fusher says:

    you have to be quick if your house is burning

    • M.S.W. says:

      This type of lock would be best suited for lockers rather then entry/exit doors.

  • Onyx says:

    GREAT IDEA!, but the design flaw, is that when you open the door you will than have to move the combination, or it just resets to 00000 when the door closes again 🙂

    • Jedobe says:

      If you look at the user scenario image on the last, it says that the combination shuffles when released 🙂

  • Very clever idea, every time I go out for a run or swim carrying my keys with me is a pain. I would certainly be very hesitant to put it on a front door of a house, but it should be secure enough for an apartment door in a building where there is an additional code at the gates.

  • steph says:

    how do you know the new code?

  • steve says:

    It would be a good concept if you forgot your keys inside. You could still get in. This is when this would be good. I keep an emergency key somewhere outside the house though. I’m never outside for too long.

  • alex says:

    Its very original,

    You can include an account by checking the box that says “I have additional You – Tube user accounts I would like to include in this partnership application” and filling out their username, password, and your relationship to them.

    You – Tube is a very efficient ways to gain leads for businesses like Empower Network.
    Another reason why You – Tube is so popular,
    is because it’s free to use. Meedan and Alive in Egypt are not as timely,
    however, as The New York Times blog The Lede, which
    features a daily synthesis of newsworththy entries from blogs, You – Tube, Twitter, and
    established, mainstream news sources.
