What do I need to run a 24-hour gym without staff?

A powered lock on the door, such as a maglock or electric strike; something that tells it when to release, such as a controller linked to your member list; a way for members to identify themselves, by fob, card, code or phone; and a payment system that removes access when someone stops paying.

Fobs or phones for gym access?

Fobs are familiar and work without a phone, but they cost money, get lost and have to be collected from people who leave. Phone access removes the hardware, as long as members have a phone with them and the door has a fallback for the day the network drops.

How do I stop people who haven't paid getting into the gym?

Tie access to payment status, so a failed or cancelled payment closes the door automatically. If the door system and the billing system are separate, someone has to keep them in step by hand, and that is where unpaid access creeps in.

What is gym check-in software?

Software that records who entered and when. In a staffed gym it is often a desk tablet or a scanner. In an unstaffed gym the door does the job: every unlock is a check-in, which is useful for spotting busy hours and shared memberships.

Running a 24-Hour Gym in NZ: Door Access, Payments and Check-In

A gym that opens without anyone at the desk runs on three things working together: a lock that can release by itself, a way for members to prove who they are, and a payment system that switches access off when someone stops paying. Most of the trouble in 24-hour gyms comes from the gaps between those three.

We make a system for this, so read the last section with that in mind. The rest applies whatever you use.

The door: a lock that can release on its own

An unstaffed door needs a powered lock, something that can be told to release rather than turned with a key. The common types are a maglock, which holds the door with an electromagnet, and an electric strike, which replaces the strike plate in the frame. If your door already has one, the hardest part is done.

What changes is what tells the lock to release. In a staffed gym it is often a button at the desk. Unstaffed, it has to be a controller that checks the member against a list and decides for itself. Have a licensed electrician look at anything involving the lock’s wiring and the fire egress requirements for your building: people must always be able to get out.

Getting members in: fobs, codes or phones

Fobs and cards. Familiar and reliable, but each one costs money, they get lost and lent, and somebody has to get them back when a member leaves.
PIN codes. Nothing to hand out, but codes get shared, and changing one means telling everyone who should still have it.
Phones.Members already carry one, there is nothing to reissue, and access can be switched off remotely. The trade-off is the day someone’s battery is flat, and what happens if the gym’s internet drops. Ask any supplier to show you exactly what the door does then.

Payments: the part that decides who the door opens for

This is where most 24-hour gyms leak money. If billing lives in one system and door access in another, a member whose payment fails keeps training until somebody notices and cancels their fob. Multiply that by a few people a month and it adds up, along with the awkward conversations.

The fix is to make access follow payment automatically: paid up, the door opens; payment failed or cancelled, it stays shut; and you can still grant access by hand for the member who pays cash or the friend helping with a working bee.

Check-in without a desk

In an unstaffed gym the door is the check-in. Every unlock is a record of who came in and when, which tells you your busy hours, which members have stopped coming before they cancel, and when one membership is opening the door for four people.

A quick checklist before you go 24/7

Powered lock on the door, and safe egress from inside at all times.
Access that switches off automatically when a payment fails.
A plan for internet and power outages, tested, not promised.
A record of every entry, and cameras where your insurer or lease requires them.
Clear rules for members about guests and training alone, in your membership terms.
Someone members can reach when something goes wrong out of hours.
