Managing keys for a multi-unit building, office floor, or retail block gets messy fast — unless one designed system handles it. A master key system from West Side Locksmith and Keys gives every person exactly the access they need and no more, under one organized hierarchy.
We design the keying schedule, cut and stamp every key, and document the system so future changes — new tenants, new hires, rekeyed units — slot in cleanly. Built on restricted keyways, the system cannot be quietly duplicated around you.
What's Included
- ✓Custom keying schedules: Designed around your building's units, floors, and staff roles — no generic templates.
- ✓Restricted keyways: System keys cannot be copied without your authorization.
- ✓Stamped and documented: Every key numbered and logged; the schedule stays with you, not in our drawer.
- ✓Scalable design: Add doors, change tenants, and expand floors without rebuilding the system.
- ✓Rekeying support: Individual doors rekeyed within the system as tenants and staff turn over.

How does a master key system work?
Each lock gets its own key, and a master key opens all of them (or a defined group). Sub-masters can cover floors or departments in between.
Can tenants copy the keys?
Not with a restricted keyway — copies require your written authorization, so the system stays intact.
We already have locks. Can they become a master key system?
Often yes, if the cylinders are compatible. We assess your existing hardware and rekey it into a designed system where possible.
What happens when a tenant moves out?
We rekey that unit's cylinder within the system — the master key keeps working, the old tenant key stops.
Is a master key system right for a small office?
If more than a few people need different levels of access, yes. We design systems from a handful of doors up to whole buildings.
