A master key system isn’t a single key that opens every door. It’s a hierarchy — a structured set of keys where each level opens a specific group of doors. The hierarchy is defined by a pinning chart, which is the document that specifies exactly which pin...

An access control system controls the lock. But controlling the lock only matters if the system also knows the state of the door. Is it open? Is it closed? Is someone coming through it right now? Without answers to those questions, the system is blind — it can unlock...

Every access control system needs a way to identify who’s at the door. For the past two decades, that’s meant a card — typically a proximity card (125 kHz) or a smart card (13.56 MHz). In recent years, mobile credentials — using a smartphone as the...

Two locks can look identical and cost very different amounts, and the reason is usually a grade stamp most people never check. ANSI/BHMA grading is how commercial door hardware is rated for durability, and specifying the wrong grade for a door’s traffic level is...

A fire door only works if it closes, latches, and holds back fire and smoke long enough for people to get out. That’s the whole job. When a fire door fails inspection, it’s usually because something small got ignored for months — a gap that grew, a label...
