What We Do

Tailored Master Key Systems for Every Property

FixMate provides full design, setup, and maintenance for master key systems of any scale — from small offices to multi-building complexes.

System Design & Planning

We start by analyzing your property layout and access requirements. Our experts design a logical key hierarchy that balances security and efficiency — from grand master to sub-level keys.

Master Key Creation & Rekeying

Already have locks installed? We can rekey your existing cylinders to work within a new master system, saving time and cost while improving overall access control.

Multi-Unit & Apartment Buildings

Property managers and landlords benefit from systems where tenants access only their units, while maintenance or management holds a master key for emergencies or repairs.

Commercial & Office Buildings

Perfect for offices, warehouses, and retail environments. Assign separate access levels to departments or roles, and manage everything with a single master key or digital equivalent.

High-Security Master Key Systems

We install restricted keyway systems using brands like Medeco, ASSA, and Mul-T-Lock, which prevent unauthorized duplication and provide extra resistance to picking or bumping.

Maintenance & Expansion

Your security needs evolve — so should your key system. We can expand, modify, or rekey your existing hierarchy as your organization or building grows.

    What Our Clients Say

    FAQ

    What is a master key system, and how does it work?

    A master key system lets one key open multiple locks while other keys open only specific doors — ideal for offices, apartments, and multi-unit buildings.

    Can I add new locks to my existing master key system?

    Yes. We can expand or rekey your current system to include new doors or areas as your property grows.

    Are master key systems secure?

    When designed properly with restricted keyways, they’re extremely secure and prevent unauthorized duplication.

    Do you create custom key hierarchies for buildings?

    Absolutely. We design systems tailored to your structure — from managers and tenants to maintenance and staff levels.
