Master Key Systems
One key for the owner, the right keys for everyone else.
The Right Access for Every Person

In a master key system, each lock has its own key, but a master key opens a group of them, and a grand master opens everything. Staff carry one key that opens only their areas. Managers carry one key that opens all of them. No more giant key rings, and no more handing everyone the same key.
Who Uses Master Keys
- Offices and multi-suite buildings
- Churches and schools
- Retail stores with stockrooms
- Apartment and rental properties
- Warehouses and shops
- Medical and professional offices
How We Set It Up
We start with a walkthrough: which doors exist, who needs each one, and how that might change. Then we design the key levels, rekey or replace cylinders, cut and label the keys, and give you a key record so you know exactly who holds what.
Add Key Control
Pair the system with restricted keyways so keys can only be copied through us with your authorization. Otherwise any hardware store can copy your master key.
Frequently Asked Questions
Does a master key system make locks less secure?
Slightly, in theory. A well-designed system with restricted keys and good records is far more secure than everyone sharing keys.
Can you expand our system later?
Yes. We design it with room to add doors and keys.
