Schlage Primus High Security Key Cntrl Exclusive Pick Resist
Patented key systems prevent unauthorized duplication of keys providing greater key control and reduced threat of a compromised key system.
The Primus/Primus XP/RP cylinder is a conventional Schlage cylinder with a few modifications. A sidebar and finger pins are added to the conventional cylinder to provide additional security. The Primus/Primus XP/RP key has a secondary bitting on the side of the blade to accommodate the finger pins. When the key is inserted, each of the side bit cuts lifts the finger pin and rotates it so that the notches in the side bar align with the notches in the back of the finger pins. When all notches on the side bar and back of the finger pins are aligned and the regular pins are aligned at the shear line the plug is free to rotate.
Primus RP is patent protected through 2029, and is backward compatible with Primus and Primus XP for Classic Obverse keyway family until 2029. Primus RP, Schlage’s high security sidebar cylinder mechanism, introduces an added level of security control. It delivers patented key control, geographical exclusivity, and pick resistance with the option of adding UL 437 drill resistance.
Whether you’re retrofitting a building or implementing a key system for a newly constructed complex, Schlage key systems deliver the security you need at every level throughout your building, campus, or worldwide facility.
