How Access Cards & Fob Systems Actually Work in a Commercial Setting
Every access card or proximity fob is tied to a unique credential stored inside a central controller. When a card is presented to a reader, the controller checks that credential against an active user list, applies any time-of-day or zone restrictions you have configured, and either releases the electric strike or magnetic lock or denies entry — all in under a second. What looks simple at the door is, behind the scenes, a layered system of hardware (readers, controllers, power supplies), software (the access management platform), and physical locking hardware including mortise locks, cylindrical locks, and door knob lock assemblies that the electronic release engages.
Most Vancouver-area office buildings that were built or retrofitted in the last decade use one of several common platforms, and our commercial locksmith technicians are experienced with the full stack: reader replacement, controller re-keying, credential format changes (125 kHz HID proximity vs. 13.56 MHz MIFARE smart card), and integration with existing alarm or video systems. We also service the underlying mechanical hardware — if your mortise lock body is worn or misaligned and causing door-held alarms or reader failures, we diagnose and repair the hardware on the same visit.
