What does master key systems involve?
In a master key system, each lock has its own key, groups of locks share a sub-master, and one master key opens everything. Staff carry one key; managers carry the master.
We plan the system with you by role, rekey existing locks into it where they are sound, and keep a record of the keying so future changes are quick. High-security cylinders can be added where key control matters.
What's included
- Keying planned by role and area
- Existing locks rekeyed into the system

Master key systems questions.
What is a master key system?
A keying plan where each door has its own key and one master key opens all of them, with sub-masters for groups in between.
Can you use our existing locks?
Usually, yes, when they are sound and share a keyway.
What happens when a master key is lost?
The affected locks are rekeyed. Restricted keys reduce the risk of unauthorized copies.
Can you rekey before we open or after we close?
Yes. Call 410-560-5940 and we will schedule the work around your opening times so staff are not disrupted.
