If you manage a commercial building, office complex, or multi-tenant property, controlling access to various areas can become a major challenge. Dozens—or even hundreds—of locks and keys can quickly turn into a logistical nightmare. That’s where master key systems come in.
At Northeastern Security, we specialize in designing and installing custom master key systems that provide convenience without compromising security.
What Is a Master Key System?
A master key system is a structured lock hierarchy that allows different levels of access using a limited number of keys. In simple terms, one master key can open multiple locks, while individual keys only open specific doors.
Example:
The tenant key opens only one apartment or office.
The maintenance key opens all common utility areas.
The master key opens all locks in the building.
This system gives building owners, managers, and maintenance personnel efficient access, while still maintaining privacy and security for individual tenants or departments.
Benefits of Master Keying
✅ Simplified Key Management
No more carrying around bulky key rings or hunting for the right key. One master key can do the work of many.
✅ Controlled Access
You can control who accesses what areas. Employees or tenants only have keys to the places they need to be.
✅ Enhanced Security
When combined with restricted keyways (keys that can’t be duplicated without authorization), master key systems reduce the risk of unauthorized duplication.
✅ Cost-Effective
Instead of replacing multiple locks during staffing or tenant changes, rekeying within a master system is faster and more affordable.
