KnocKey laughs at keyholes

The KnocKey offers an alternative to the traditional locking methods use at home by doing away with the standard keyhole. Instead, all you need to do when you want to enter your home would be to punch in the correct code on the KnocKey’s keypad and hold it up to the door. The code will be played back with a correct sequence resulting in an unlocked door. The only drawback would be forcing your brain to set some more space for yet another password sequence, something most of us can ill afford these days with the number of e-mail addresses, PIN codes, and user accounts we have.
