How a Master Key System Works
Each lock in a master key system accepts two or more keys: the individual "change key" for that door, and a master key that opens a group of doors — or all of them. Larger properties can add levels, like a grand master for the owner, sub-masters for each department or building, and individual keys for tenants or staff.

The Access You Need — Built to Last
Your master key setup needs to be durable and reliable while giving you easy access to your facilities. We take the time to design a hierarchy that matches how your property actually runs, keep accurate key records, and recommend restricted keyways so keys can't be copied at the hardware store.
Need even more control? Combine master keying with card access control on high-traffic exterior doors. After tenant or staff turnover, we can rekey individual locks without disturbing the rest of the system.

Frequently Asked Questions
Can you master key my existing locks?
In many cases, yes — if the existing locks are compatible and in good condition, we can rekey them into a master system.
How do I stop people from copying master keys?
We use restricted keyways where blanks are only available through an authorized locksmith with owner permission.
