Key Control: The Medeco Factory is the only source for the patent protected key blanks.  New 
                      keys can only be cut with the user's permission on special key machines 
                      available exclusively to Licensed, Medeco Dealers. Each railway can be assigned
                      unique key codes restricted to their use ONLY.

Pick Resistance: Whereas common pin tumbler locks can easily be picked open, Medeco's 
                      elevate and rotate design is virtually pick proof.

Protection Against Physical Attack: Medeco cylinders safe-guard against drilling by placing 
                      hardened steel inserts strategically throughout the lock

Durability: Warranted for two years, Medeco cylinders are manufactured with the highest quality 
                      materials and machined with the closest possible precision.
                      Locks have a proven track record of reliability even in the harshest conditions.

Visual Control: Both keys and switches can be marked to provide easy, positive identification.

Multiple Stack Switches: Extra contact blocks are available to control several circuits at once.
