A key on the phone
The guest opens a dedicated key screen with their room, an unlock action and how long the key is valid, plus an add-to-wallet button for Apple or Google Wallet.
Digital room keys
The room key, on the guest's phone.
When a guest's stay is confirmed, Monsieur can put their room key on their phone: a secure link with an add-to-wallet button, issued automatically at check-in and revoked at checkout. Your front desk keeps full control, and you can try the whole flow against a built-in demo lock today.
Issued and revoked on time
Keys are issued automatically when the stay begins and revoked when it ends, and they follow a room change or an extension. A safety net escalates any revoke that needs a human.
Provider-agnostic by design
Monsieur is built to sit in front of your lock system rather than replace it, with a room-to-lock mapping your team controls, so the guest experience stays the same whichever locks you run.
Their room, ready on the lock screen.
Once the stay is confirmed, the guest gets a link to their key with an add-to-wallet button. The key screen shows the room, an unlock action and the time the key is valid until, so there is nothing to collect at the desk and nothing to lose.
Because the key is tied to the stay, it appears when they check in and stops working when they check out, with no plastic card to hand back.
You stay in control of every key.
Keys issue and revoke themselves off your stay events, but your team keeps the manual controls that matter: issue, revoke or resend a key from the stays screen, and a clear attention queue for any key that needs a person to close it out.
Under the surface, issuing and revoking run through a safe, at-most-once pipeline with a deadline on every revoke, so a key is never left live by accident. The key link itself is never written to a log.
Built to meet your lock system.
Monsieur is provider-agnostic on purpose. The guest experience, the add-to-wallet button and the whole issue-and-revoke lifecycle are built once, and the lock system connects behind them, with your rooms mapped to your locks in settings. Native Apple and Google Wallet passes arrive as each lock integration is certified.
We are rolling this out with lock partners across the major hotel ecosystems, and you can run the entire flow today against a built-in demo lock, so you see exactly what your guests will get. Tell us the locks you run at signup and we will wire your property as each integration is certified.
How it works
How a digital key works.
1
The stay is confirmed
When a guest's stay starts, Monsieur issues a key for their room automatically, or your team issues one in a tap.
2
The guest gets their key
They receive a secure link with an add-to-wallet button. The key screen shows the room and how long it is valid.
3
It ends with the stay
At checkout the key is revoked automatically. A room change or an extension updates it, and any revoke that needs attention is flagged for staff.
Questions
Digital key questions.
How does the guest get their key?
As a secure link to a key screen with an add-to-wallet button. It shows their room, an unlock action and when the key expires. Email delivery is built in.
When is a key issued and revoked?
A key is issued when the stay begins and revoked when it ends, and it follows a room change or an extension. The whole lifecycle runs on a safe, at-most-once pipeline with a deadline on every revoke.
Which door locks does it work with?
Monsieur is provider-agnostic and built to connect to the major hotel lock ecosystems. Those integrations are being certified one by one; today you can run the full flow against a built-in demo lock. Tell us your lock brand at signup and we will connect your property as its integration ships.
Do I need digital keys turned on to use Monsieur?
No. Digital keys are optional. You connect a lock provider and switch on issuance when you are ready; ordering, check-in and the guest directory all work without it.

In-room ordering
Guests scan the room QR code, browse a branded menu and send an order to the room. Tickets land on a real-time kitchen display the moment they confirm.
Read moreOnline check-in
Guests fill in their details and sign before they arrive, from a secure link, so the front desk has a complete registration ready instead of a queue at the counter.
