A code for every booking
Each booking gets its own PIN, valid from the start to the end of the slot. It goes out by text right after booking.
Private gym hire, without staff
Your private gym, open without you.
Customers book a slot, pay by card, Apple Pay or Google Pay, and get a door code by text that only works during their booking. Nobody has to be on site.
£890 one-off setup, then £22 a month
How it works
Simple for your customers. Hands-off for you.
Your customers
Book a slot
They pick a free time on your booking page. The whole gym is theirs for that slot.
Pay online
Through Stripe: card, Apple Pay or Google Pay.
Get a door code
A PIN arrives by text right after booking. It opens the door only from the start to the end of their slot.
You
Set hours and prices
Opening hours, slot length, hourly prices by day and time, and discount codes.
Get paid
Payments go straight to your own account. No cash, no reception, no texting codes late at night.
Keep an eye on it
See every booking, occupancy and revenue for each location, and block time for cleaning when you need it.
What you get
Everything an unstaffed gym needs to run itself.
Backup code if the internet drops
If the internet is down and a new code can't reach the keypad, the customer gets a stored backup code instead.
Payments through Stripe
Customers pay by card, Apple Pay or Google Pay. The money goes straight to your account.
Prices by day and time
Charge more at peak times and less off-peak, set prices for specific dates and hand out discount codes.
Unlimited locations
Add new locations yourself, at no extra cost. Each one has its own opening hours, prices and doors.
Numbers you can act on
Revenue, occupancy and busy hours for each location, with a CSV export for your accountant.

Marek AndrášikFounder
I build and run Sparekey, with almost 20 years in product development behind me. You deal with me directly, from the first call to launch and after.
Setup
From first call to open doors in about a month.
Demo call
We go through your space, your doors and your building, and agree what to set up.
We set it up
Your booking page, prices, Stripe, and texts that arrive from your gym's name.
Door access
A qualified installer fits the 2N keypad and maglock to your fire regulations. We connect it and test the codes.
Go live
A few test bookings with real payments, then you open.
FAQ
What private gym founders ask first.
Do I need anyone on site?
No. Customers book and pay online, get their code by text and let themselves in. You manage bookings, prices and blocked times from the admin.
What if the internet goes down?
If a new code can't be stored in the keypad, the customer gets a stored backup code instead, so they can still get in.
Is a maglock safe in a fire?
Yes, when it is fitted properly. A qualified installer wires it to local fire regulations: it releases on fire alarm and on power loss, and there is an exit button and a break-glass on the inside. See door access in the UK.
I rent my unit. What do I need?
Your landlord's consent before the installer fits the keypad and maglock. We check your door, uPVC included, and a shared building entrance during setup.
Who receives the payments?
You do. Customers pay by card, Apple Pay or Google Pay through Stripe, and the money goes straight to your account.
How long does setup take?
Plan about a month from the first call. Two things set the pace: Stripe's approval of your account and your installer's diary. Prices and test bookings fit inside that month.
