What is gym access control software?

Gym access control software lets you decide who can open which doors at your gym, and enforces it automatically based on each member's membership status. It's what makes 24/7 and unstaffed hours possible without handing out keys.

Members tap a fob on the reader by your door or unlock from their phone. The system checks their membership at that moment, opens the door, and logs the entry as attendance.

Door access tied to every membership

Freeze, cancel, or end a membership and that member's fob stops working on its own. Every tap is checked live, so you're never revoking access by hand.

Give every member their own key

Each fob belongs to one member, so every entry has a name on it and you can revoke a single fob without changing anything for anyone else.

Open 24/7, even when the internet drops

Set the hours your doors unlock, and open any door from your phone when someone needs a hand. Your door hardware remembers who's allowed in, so an internet outage doesn't leave anyone stuck in the parking lot. Every tap logs attendance automatically.

Frequently Asked Questions

How does 24-hour gym access control work?

Members carry a fob or unlock from the Gymdesk app. Each tap checks their membership in real time and opens the door only if they're eligible, so your gym can stay open overnight without staff on site.

Will my existing key fobs or door hardware work?

It depends what your members carry today. Our readers use 13.56 MHz NFC fobs, so fobs on that standard can often carry over, while older 125 kHz fobs can't. The reader itself is new either way — send us a photo of your current fob and we'll confirm before you order anything.

Who installs the door hardware?

Rhombus's installer network handles it. They find a certified local installer, get competing quotes, book the job, and stay on it until the door works — so you're not calling around for an electrician yourself.

What happens when a member stops paying?

Access follows the membership. When a membership is frozen, canceled, or lapses, that member's fob stops working automatically, so there's no list to keep and nobody to chase.

Does opening the door check the member in?

Yes. Every fob tap records attendance for that member, so early-morning and unstaffed visits still show up in your numbers without a second check-in step.

Can members get in without a smartphone?

Yes, and that's why fobs come first. Members without a smartphone carry a fob, members who'd rather not carry anything unlock from the Gymdesk app, and the same membership rules sit behind both.

Can I stop members from sharing fobs or letting people in behind them?

Each fob belongs to one member, so you can see exactly who came in and switch off one person's fob without touching anyone else's. Someone slipping in behind a member is a different problem, and that one takes a camera — which Rhombus offers alongside the door hardware

Can different membership tiers get different access hours?

Memberships control which doors each member opens, and your gym runs on one set of access hours across all of them. Different hours by tier isn't supported today, but it's a tracked request, so tell your account manager if you need it.
