KeyMark® by Medeco® offers patented key control without the physical pick and drill resistance of Medeco's Biaxial® product line. Medeco manufactures KeyMark for applications when key control is a necessity, but resistance to physical attack may not be as high a priority. KeyMark cylinders will fit into most common locks, including conventional rim and mortise cylinders, knob cylinders, and Best® style and other lock manufacturers' interchangeable core installations. KeyMark is an entire system of affordable replacement cylinders with genuine, patent protected key control from Medeco, the company who pioneered high security key control. Not all Medeco dealers are KeyMark dealers.
