Our Services
Master Key System Services We Provide
We build systems that fit how your business or property actually operates, clean, organized, and secure.
Custom Master Key System Design
No two buildings operate the same way. We design your system around how your team moves, how your property is structured, and how much access control you need. We create: Single-level systems Multi-level (hierarchical) systems Department-based access systems Tenant-specific access systems Property manager/maintenance access setups Restricted key systems for high-security areas Each lock is keyed intentionally so the structure fits your workflow—not the other way around.
Master Key Installation
Once the design is approved, we rekey or install locks to match the master key plan. We work with existing hardware whenever possible to keep costs efficient. We install: Mortise locks Deadbolts Lever locks Commercial storefront locks High-security cylinders Restricted keyway systems Every lock is tested for smooth operation and precise access control.
Adding New Locks to an Existing System
If your building expands or you add new doors, we can integrate additional locks into your current system seamlessly. You keep the same master key—just gain more control.
Master Key System Repair & Reconfiguration
Systems need occasional updates, especially when: Employees leave Departments change Tenants move out Keys go missing Locks wear out Building layout changes We repair, rekey, restructure, and reconfigure the system so it continues functioning as intended.
High-Security Master Key Systems
If your building requires maximum security, we design master key systems using restricted keyways. These systems prevent unauthorized key duplication, keys cannot be copied at a hardware store or kiosk. This is ideal for: Hospitals Office buildings Retail Warehouses Multi-tenant commercial spaces Schools and universities Government facilities You maintain complete control over who gets a key.
Rekeying for Master Key Systems
Rekeying is the fastest way to maintain security when keys are lost or staff changes. We reset the pins inside the locks so the old keys stop working, while keeping the same master key hierarchy intact.
