Patented Key Systems

Think your keys can’t be easily duplicated? Think again! – “Do Not Duplicate” when stamped on non patented keys means nothing. These words alone will not stop a locksmith or even a corner hardware store from copying your keys for anyone who brings in a sample.

Remember, whenever your keys are out of your hands, so is your security. Not to mention your peace of mind. We offer patented key control systems like Mul-T-Lock’s MT5+ and Interactive+ advanced platforms to give you better control.

MT5+ keys combine patented, triple-locking technology and advanced key control for enhanced security.


Mul-T-Lock’s Interactive+ key system addresses High Security concerns while responding to functional needs with patented, dual locking technology.
