How Fob Entry Works in an Apartment Building
A small reader mounts at the door, a controller sits behind the scenes, and every fob carries a unique ID. Tap the fob, the controller checks it against the approved list, and the door releases. That list is the whole point: you decide who's on it, which doors each fob opens, and even which hours it works — handy for porters, package rooms, and gyms. Every tap gets logged, so if a door was propped open or a fob used at 3 a.m., there's a record. The hardware is simple; the management layer is where a good installer earns the fee.
The Fob Cloning Problem — and How to Beat It
Here's the uncomfortable truth: the basic proximity fobs handed out by many NYC buildings can be copied at a kiosk in minutes for a few dollars. If your building still runs on those, your "controlled" door is anything but. The fix is encrypted smart credentials — fobs and cards that perform a cryptographic handshake with the reader instead of just broadcasting a number, which makes casual cloning impractical. Many systems also support phone-based credentials that are harder still to duplicate. We'll tell you straight whether your current fobs are cloneable and what a reader-and-credential upgrade involves, without replacing the parts that still serve you well.
Tenant Turnover Without the Rekeying Bill
Tenant turnover is where fob systems beat metal keys decisively. A move-out used to mean rekeying the lobby and reissuing keys to everyone — or, more honestly, doing nothing and hoping. With fobs, the departing tenant's credential is deactivated in seconds and the rest of the building never notices. Supers, dog walkers, and cleaners can carry fobs limited to certain doors and hours. And when management changes, the entire credential list transfers with the system, so the new company isn't starting from a shoebox of unlabeled keys.
Common Questions
Can key fobs be cloned?
Basic proximity fobs can be copied at kiosks around the city. Encrypted smart fobs resist cloning because they authenticate with the reader instead of broadcasting a fixed ID. We can upgrade readers and credentials on most existing systems.
Do fob systems work for both apartments and offices?
Yes. The same reader-and-controller setup runs apartment lobbies, amenity spaces, office suites, and service doors — only the permissions differ.
What happens when a tenant loses a fob?
The lost fob is deactivated immediately and a new one issued. No rekeying, and no lingering risk from the missing credential.
How much does a key fob entry system cost?
It depends on door count and credential type. You get a transparent quote before work begins — no hidden fees.
