Medeco® High Security Locks was born as “Mechanical Development Company,” a small tool & die shop in Salem, Virginia. In 1968, the owners and employees of the company developed a unique locking principle of angled key cuts and elevating and rotating pin tumblers that provided millions of key combinations and a level of security that was unmatched in its time. The angled cuts on the key were used to rotate unique bottom pins. Hardened steel inserts and a sidebar were used to produce a cylinder that was highly resistant to virtually all forms of attack. Soon after, Medeco was officially formed and immediately set the standard for high security and key control.
Medeco continues to be one of the world's leading producers of high security locks with more than 400 employees and 130,000 square feet of office and manufacturing space. Since its inception in 1968, Medeco has set the standard for high security and key control. The stage has been set for even more retrofit versatility and new product innovations that will allow Medeco to continue its leadership in the key control, retrofit cylinder marketplace.
