The simple logic behind master keys, and how to plan one for your building.
A commercial master key system arranges keys in levels so the right people open the right doors and no more. At the bottom, each door has its own change key that opens only that door. Above it, a master key opens a group of doors, and at the top, a grand master can open everything. Our master key system service designs this hierarchy around how your business actually runs.
Picture an office: each employee's key opens their own space, a manager's master opens the whole suite, and the owner's grand master opens every door across locations. That structure means a lost change key is a small problem, since it only affects one door, not the whole building.
A good system is mapped before any cylinder is cut: every door, every group, and room to grow as you add space. We often build it on a restricted keyway so copies cannot be made without authorization, which ties into high-security hardware. When staff change, a targeted rekey resets only the affected doors, and access control through our access control service can layer on top for sensitive areas.
Our commercial team designs and maintains these for offices and properties across Raleigh and Durham. Contact us to plan one.

If you only take one thing from this, take this: handling a lock problem on purpose, before it becomes a crisis, is almost always cheaper and calmer than handling it in a panic at the worst possible moment. A little planning, a spare key, a rekey after a move, goes a long way.
