InstaKey® High Security Door Locks

High Security Cylinders

High Security (HSEC) cylinders are circular shaped and incorporate Medeco-InstaKey® Biaxial security solutions. These HSEC cylinders are designed to utilize two levels of biaxial key cutting (angled cuts), restricted keyways, and drill resistant housings. They can be supplied in industry “standard” line or removable core configurations. Our HSEC cylinders are designed to retrofit into an assortment of manufacturer’s locksets and housings (i.e. Corbin-Russwin, Falcon, Medeco, Sargent, Schlage, Yale, etc.). Key-n-Knob cylinders are designed for standard cylindrical knobsets and leversets.
