Master key systems in Washington, DC
A master key system means one key can open many locks while each other key opens only the doors it should. It cuts down key rings and makes it clear who can get in where.
- Phones answered Monday to Sunday, all day
- Mobile service vans

How a master key system works
Each cylinder is pinned to accept two or more keys: its own change key and a master key. Larger systems add sub-master keys, for example one per floor or department.
Who uses them
- Office buildings
- Rental and condo buildings
- Hotels
- Schools
- Medical offices
- Larger homes with many doors
Planning a system
- List every door and who needs to open it.
- Group users into levels such as owner, managers and staff.
- We design the key chart and pin the cylinders to match.
- Keys are stamped and issued, and you keep the key record.
Keeping it secure
Pair a master key system with a restricted keyway so keys can't be copied at a hardware store. Keep a written record of who holds which key and rekey affected cylinders when a key goes missing.
Frequently asked questions
Can you add to an existing system?
Often, if we have the key chart or can decode the existing pinning.
