The Knock N'Lock

The lock is one that cannot be picked, but will open by an authorised person, even after a burglary attempt.

Suppliers of inventive and advanced security products, Elvey Security Technologies together with E-Lock bring installers a new innovation in security. The Knock N'Lock, with patented Knock Code Technology, the transfer of data through solid materials by discrete mechanical knocks.

The Knock Code is the combination of the time intervals between knocks. The Knock Code is encrypted and has billions of combinations. Even if the code was recorded and played, the locking mechanism will not react.

To open the lock enter a code on the Knockey and press it to the outside of the door or lock. Each Knockey can open any number of locks with either the same or different codes. You only need to carry one Knockey.
