Our Hardware & Key Services
Master Key Systems
Custom-engineered master key hierarchies that give facility managers tiered access control across multiple zones — without compromising individual space security.
High-Security Cylinders
Installation and service of ANSI/BHMA-rated high-security cylinders offering superior pick, drill, and bump resistance for critical access points.
Commercial Door Hardware
Supply and installation of commercial-grade locksets, closers, exit devices, and panic hardware — specified to meet ADA, fire code, and facility requirements.
Rekeying & Lock Replacement
Rapid rekeying and lock replacement services to restore key control after personnel changes, security incidents, or hardware failures — minimizing operational disruption.
Restricted Keyways
NSI maintains proprietary restricted keyways, providing clients with complete key control within their facilities. Key duplication is strictly limited — authorized personnel must submit requests directly through NSI to ensure the integrity of your key system.
Emergency Lockout Response
