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 technology and advanced key control for enhanced security. Telescopic pins create a dual shear line while the innovative, patented Alpha Spring located at the tip key, engages a unique pin at the rear of the locking mechanism to create an additional shear line for enhanced intrusion resistance.

The side-bar mechanism also allows for millions of possible combinations making MT5+ an ideal choice for complex keying needs. In addition, MT5+ keys control unauthorized key duplication via a coded magnetic duplication card – which can only be read by a dedicated Mul-T-Lock key cutting machine at an authorized locksmith.
