Not feeling secure with that deadbolt lock on your front door? Check out the Numlock Handle. Designed by Jaeseok Han, the Numlock Handle features a number-combination lock that prevents “unauthorized” access to a room (or building). The door handle does not turn unless the correct four-number combination is entered. Good luck opening the door in an emergency.
Secure? Probably not (brute force, anyone?). But, the coolest feature of the Numlock Handle is its ability to automatically lock itself by shuffling the numbers after each successful door entry. Plus, you can easily change the combination and even replace (or supplement) the numbers for braille. So, what happens when you forget the combination? No idea. Hopefully, if the Numlock Handle ever enters into production, there will be a master key to unlock the handle in emergency situations .
Just make sure no one is looking over your shoulders as you enter the combination.

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.
It wouldn’t be secure for any front door. The problem is that there are only 4 tumblers, which gives 10,000 possible combinations.
Given enough time, an intruder could potentially “brute force” his way in — which is possible, if say, you go on vacation.
A very large hammer in the hands of a determined thief. Dumblock.
I need one of these to lock my teenager out of the pantry and keep my alcohol lock up. Where can I buy one?????
