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 SMS right after booking.
Booking and door access for private gyms
Your private gym, open without you.
Customers book a slot, pay online and get a door code by SMS that only works during their booking. Nobody has to be on site.
€990 one-off setup, then €19 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: cards, Apple Pay and Google Pay.
Get a door code
A PIN arrives by SMS 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, 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 lock, the customer gets a stored backup code instead. Works with any lock.
Payments through Stripe
Customers pay with cards, 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.
Door access
Two ways to open the door.
Both work with time-limited codes.
2N keypad + maglock
A keypad outside and a magnetic lock on the door, fitted by a professional door or access installer. Built for doors that open many times a day with nobody around.
- Reliable for unattended operation
- Hard for customers to tamper with
- Needs an installer, plus power and internet at the door.
Nuki smart lock
A smart lock with a keypad that fits on your existing door. Simpler and cheaper to start with.
- Fits on many existing doors
- Lower cost to start
- It can't be secured well against tampering by customers.
Other locks with time-limited PIN codes: ask us.

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 and Stripe payments.
Door access
An installer fits the 2N keypad and maglock, or you mount a Nuki. 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 SMS 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 lock, the customer gets a stored backup code instead, so they can still get in. This works with any lock.
Which doors and locks work?
We recommend a 2N keypad with a maglock, fitted by a professional installer. Nuki is a simpler, cheaper alternative, but customers can tamper with it more easily. Several doors or a shared building entrance are solved during setup at no extra cost. See door access options.
Who receives the payments?
You do. Payments go to your own account through Stripe, which we set up for you.
How long does setup take?
Plan about a month from the first call. Two things set the pace: your payment provider's approval and, for 2N, your installer's diary. Prices and test bookings fit inside that month.
Can I open more locations later?
Yes. You add new locations yourself in the admin, at no extra cost. Each one has its own opening hours, prices and doors.
