Master Key Systems
Create secure, scalable access with a professionally designed master key system (MK/GMK). One key opens what it should—nothing more.
From small suites to multi-building complexes, we design pinning charts, restrict key duplication, and leave room for future expansion.
- Keyed-alike groups, MK/GMK hierarchies
- Pinning charts with expansion space
- Restricted/controlled keyways & key control
Apartments & Multi-Unit
Simplify turnovers and reduce rekeys with controlled key hierarchies and keyed-alike groups.
Offices & Facilities
Segment access by role and area, maintain audit-friendly pinning records, and plan for growth.
Frequently Asked Questions
Can you expand my current system?
In many cases yes. We can audit your existing cylinders and charts, then add new levels or keyed-alike groups with future expansion in mind.
What is a restricted keyway and why use it?
Restricted or proprietary keyways limit unauthorized duplication and improve key control, ideal for offices and multi-unit properties.
