The Safest Lock in The World

Features:

• No keyhole or contact point on the outside of your door, affording MAXIMUM security in a lock that cannot be picked or tampered with.
• To open the lock, enter your Opening Code (4-6 digits) on the KnocKey and press it to the outside surface of the door.
• The KnocKey then transfers the Opening Code to a discrete sequence of Mechanical Knocks (Knock Code) to the lock through solid materials (metal, wood, plastic, glass, etc.). The lock will be opened if correct code is applied.
• The Knock Code is produced and encrypted by KnocKey or Mounted KnocKeypad and has billions of combinations. The lock will not open if the code is recorded or played back.
• The Knock Code is the combination of the time intervals between knocks.
• Each lock can be easily programmed by the user to be opened by 125 opening codes.
• For high traffic areas we offer a Mounted KnocKeypad that can be attached to the door or frame for maximum security without any wiring or installation problems.
• Your KnocKey can open an unlimited amount of locks with either the same or different codes. You only carry one key!
• If your KnocKey is lost or stolen, simply purchase another KnocKey and enter in your master security code.
• The safest lock for your home, apartment, business, warehouse, marine and trucking.
• Our Knock Code Technology and all the unique lock designs are patented worldwide.
