A relocker is a device or design that “relocks” the locking mechanism in the event of tampering. Generally, a spring loaded plunger is mounted inside the safe, with a trigger mechanism that will fire if the lock box is damaged. UL group 2 locks and better have internal spring loaded mechanisms that will relock their deadbolts if the back cover of the lockbox is removed or punched out. A new invention developed by Rhino Safe Co. (Rhino Metals, Inc.) is the integrated relocker. Rhino Metals, Inc. patented a lock design that incorporates additional modes of relocking geometry into the parts of the boltwork. This design is used in conjunction with the group 2 UL listed lock’s internal relocker, and the standard spring loaded relocker to offer up to 5 times the security of other brands.
