Managing a growing business or a multi-unit property shouldn't mean carrying around a heavy, confusing ring of keys. A Master Key System drastically simplifies your daily operations by allowing multiple customized keys to open specific doors, while a single "Grand Master" key bypasses every lock in the building. We design, implement, and maintain strategic keying hierarchies tailored specifically to your organization's operational needs.

How the Hierarchy Works

We mathematically map out the internal pins of your lock cylinders to create tiered access. The business owner or property manager holds the Grand Master Key, which opens every single door. Department managers are given Sub-Master Keys that open only the doors on their specific floor or wing. Finally, individual employees receive standard Change Keys that exclusively open the front entrance and their personal office door, completely restricting them from sensitive areas like server rooms or inventory closets.

Property Managers & Landlords

If you manage apartment complexes or multi-family homes in Boston, a master key system is an absolute necessity. It allows your maintenance and cleaning crews to access units for emergency repairs or turnover without having to track down a specific tenant's key. We also utilize restricted keyways—patented key blanks that legally cannot be copied at a local hardware store.

Scalable Security Integration

A well-designed master key system is highly scalable. As your company hires new staff or expands into newly leased office space, our locksmiths can effortlessly integrate the new locks into your existing hierarchy. We maintain detailed, secure records of your lock pinning charts, allowing us to rapidly issue new keys.
