Access Control System Installation: Keypads, Fobs, and Electric Strikes Explained
A successful access control system installation starts with understanding the three core hardware layers. The credential device — a PIN keypad, proximity fob reader, or card reader — is what the user interacts with. The locking mechanism — most often an access control mortise lock, an electric strike, or an electromagnetic lock — is what physically secures or releases the door. The controller or power supply ties the two together, deciding whether the credential presented is valid and then sending the signal to release the latch. Getting all three layers matched correctly is where experience matters most, and it is exactly where our mobile technicians focus during the site assessment.
Keypads suit high-traffic doors where issuing physical fobs to every visitor is impractical. PIN codes can be changed remotely or on the panel itself the moment an employee leaves, making them a cost-effective credential layer for small commercial offices. Proximity fobs and smart cards go a step further: each fob carries a unique ID, so the access log shows exactly which credential opened which door and when. Electric strikes replace the strike plate in the door frame and release the latch when a valid signal is received, leaving the door lock body itself untouched — a huge advantage when you want to keep an existing mortise lock or commercial locksmith-installed deadbolt in place while adding electronic control. Our team installs and wires all three hardware types and confirms every component is functioning before we leave the site.
