In-house services
Private saunas, meeting rooms, lockers and late checkout — booked and paid by the guest, with a key that works only for that slot.

The Challenge
- The private sauna, the meeting room and the bikes are booked by phoning the desk
- Add-ons are sold by whoever is on shift, so the revenue depends on who is on shift
- A guest who wants a locker or late checkout has to come down and ask
- Nothing in-house is bookable before arrival, so it is never part of the decision to book the room
How UnlockOS Helps
- Guests book the private sauna, the meeting room or a bike slot on their phone, before or during the stay
- Each booking comes with a key that opens only that room for that slot, and settles on the same card as the stay
- Lockers and late checkout are self-service: pay, and the key or the extended stay just works
- In-house inventory is on the same plans and calendar as the rooms, so it never double-books

Seamless experience from start to finish
Open the in-stay page
From the check-in confirmation, before arrival or from the room.
Book the sauna for 20:00
Pick the slot; pay on the card already on the stay.
Issue the sauna key
Valid 20:00–21:00 for that room only.
Block the buffer
21:00–21:20 cannot be booked; cleaning staff get a key for that window.
Settle with the stay
In-house bookings appear on the same settlement as the room.
Get started in 3 steps
List the in-house spaces
Private sauna, meeting room, gym, bike rental, lockers. Each gets slots, a price and a cleaning or turnover buffer.
Attach them to the stay
Guests see what they can book from the check-in link and from the in-stay page. Members and repeat guests see their rate.
Let the key enforce the slot
A booked sauna opens for the booked window and no other. Lockers release at checkout. Late checkout keeps the room key alive.
Reservation, walk-in or membership — your call
How you take guests is the owner's decision, not the industry's. Mix all three and they still share the same plans and inventory.
By reservation
In-house spaces are sold by time slot, with buffers. The key enforces the window.
Walk-in
A guest standing at the sauna door can book the next free slot on their phone and get in.
Membership
Residents, long-stay guests and club members can get member rates or included allowances on the same inventory.
Built for your workflow
In-house bookings by the guest
Private sauna, meeting room, gym, rental gear — booked by time on the guest's phone.
Keys only for the slot
The booking issues a key that works for that room and that window. Nothing to hand over.
Lockers with the stay
A smart locker is assigned when the guest pays and released at checkout.
Late checkout as a product
Sold in the in-stay page; the room key is extended automatically.
Buffers between bookings
Cleaning or turnover time is blocked after each slot so the next guest never walks into a wet sauna.
Same calendar as the rooms
In-house inventory lives on the same plans and calendar, so staff and guests see one truth.

KEYVOX opens the door. UnlockOS runs the business.
KEYVOX smart locks, gates and lockers are built into UnlockOS. The moment a booking or payment completes, a key only that person can use (PIN, QR or LINE) is delivered, and it expires on its own. Hardware choice, installation and wiring are covered on the KEYVOX side.
Sauna doors, meeting rooms and lockers are KEYVOX hardware; the hotel page on the KEYVOX side lists what fits each door.

Built so you can add sites without hiring an IT team.
Open the second site by copying the first
Plans, pricing, opening hours and key rules from the first site are copied to the next one. Nothing is rebuilt from scratch.
Separate permissions for HQ and each site
HQ sees every site; a franchisee or manager sees only their own. When someone leaves, you remove their role — nothing physical to collect.
Revenue and check-ins per site
Compare revenue, check-ins and members per site from HQ. It feeds franchisee support and the next opening decision.
