The Knock N’Lock™ Technology is a result of a revolutionary idea to develop a highly secure lock that does not need a keyhole or any contact point from which someone could tamper with it.

This idea resulted in the development of the patented “Knock Code Technology” that uses discrete series of mechanical knocks that transfer the encrypted information that opens the lock.

This information is generated by a small hand-held device called the KoncKey™ that is held against the door or its frame, may it be metal, wood, glass or other materials.
The lock then listens to the Knock Code and opens if it determines that it is the correct code.

The fact that the “Knock Code” contains a pulse code of 16 digits and is comprised of a combination of different encrypted and random codes means that there are billions of possible code combinations which makes these locks extremely safe.

The “Knock Code” also uses random generation of part of the code so it never uses the same exact code twice.
This makes it impossible to imitate the Knockey™ even by recording the code.
In addition to the fact that Knock N’Lock™ locks cannot be seen from the outside thereby maximizing security.
Knock N’Lock™ locks passed high security tests in Germany (VdS).
