Calisto Key turns bookings, tasks, and visits into digital keys that work the way your operations work. Use it on its own as your access platform or plug it into Calisto One so your locks, stays, and fieldwork all run from the same source of truth.
CalistoOS is the engine. Calisto One is the hub. Calisto Key is your digital front door.
Most digital key systems live in their own world or bolt onto a single PMS. Calisto Key lives in your operations hub. Bookings, stays, viewings, and tasks already sit in Calisto Ops or your existing systems. Calisto Key turns that context into secure, time bound access for everyone who needs it across stays, showings, and service visits.
When a guest checks in, a viewing is scheduled, or a maintenance visit is created in Calisto Ops, Calisto Key issues the right digital key automatically. When the stay ends, the viewing is over, or the task is closed, access is revoked without anyone collecting cards or changing codes by hand. Starting with Calisto Key alone? You can add or import bookings and visits without changing PMS.
Calisto Key uses your unified people database to grant access by role: guests for their stay, owners for their homes, housekeepers and maintenance by schedule, and vendors by appointment. Everyone gets what they need and nothing they do not, whether you run a single home or a global brand.
Under the hood, Calisto Key runs on Azure, integrates with Dynamics and Microsoft IoT Hub, and uses CalistoOS as the shared data model. You keep the power of your Microsoft stack while owners and guests simply experience smooth, secure access under your brand.
Calisto Key turns the workflows you already run in Calisto One into digital access flows. If you are not on Calisto One yet, you can start with manual entries, CSV imports, or API connections to your PMS and upgrade when you are ready. There is no extra system for your team to babysit and no mystery logic in a third party app. You get a clear path from confirmed stay or scheduled visit to door open, with every action logged.
Guests and clients complete online check in, ID verification, and payment in Calisto Navigator. Owners and agents confirm visits and showings. Once conditions are met, Calisto Ops marks the booking, stay, or appointment as ready for digital access. Starting with Calisto Key alone, you can capture the same details through simple forms or imports.
Calisto Ops knows who is staying, visiting, or working where. It links bookings, tasks, and deals to specific rooms and units. It defines roles for guests, owners, staff, and vendors. Calisto Key uses this structure to decide which doors each person should be able to open and when. If you are integrating from another PMS, that same structure can be synced or imported.
When a stay or visit reaches the right status, Calisto Key talks to your smart lock providers. It creates or updates time bound credentials and delivers them through your chosen guest experience: wallet passes, app based keys, PIN codes, or a mix of all three. Behind the scenes, Microsoft IoT Hub and APIs keep device state in sync and standardized.
Lock events feed into Calisto Signal and Calisto Ops. Lockouts, battery alerts, and repeated failed attempts become tasks, tickets, or alerts. Signal is included for Calisto Key and Calisto Ops subscribers so you always see what is happening at the door. When you want Calisto to handle alerts after hours, you can add Calisto 24·7 Monitoring and incident response on top, using the same data and devices.
Calisto Key can start life as a focused access platform. When you connect it to Calisto Ops, Navigator, Signal, Assure, Deals, Sync, and 24·7, it becomes a digital access layer that sits across your entire operation so access is always driven by the same data your teams already trust.
Ops holds the master record for people, properties, bookings, tasks, and tickets. Calisto Key uses that same record to decide who should get access and when. Every key issuance and revocation shows up in the timelines your team already checks.
Navigator gives guests, owners, and buyers a clean portal or app. Calisto Key adds a Get my key step to that experience so keys become part of a branded journey, not a separate login or a generic vendor app.
Signal connects your sensors, hubs, and controllers. Calisto Key focuses on locks and access. Together they give you live awareness of who should be able to open which doors, whether devices are healthy, and how your team responded when something went wrong. Signal is included with every Calisto Key and Calisto Ops subscription, and you can upgrade to Calisto 24·7 Monitoring when you want our team to act on alerts, not just surface them.
Assure standardizes inspections and condition reports. Calisto Key adds access checks into those routines so you confirm that digital keys work before guests arrive and create tasks automatically if doors, bridges, or batteries need attention.
Deals tracks mandates, viewings, offers, and contracts. Calisto Key issues time bound access for showings, inspections, and handovers so agents and buyers can see properties on schedule without juggling physical keys or code lists.
When a guest or owner calls after hours, 24·7 sees their booking, key status, and recent access events. That context lets your team resend keys, issue one time access, or dispatch help safely with every action logged.
Calisto Key is designed for teams who want the ease of keyless access without giving up control. Whether you run a single design led hotel, a mixed portfolio of villas, or a brokerage that also manages homes, Calisto Key meets you where you already work — inside Calisto One or alongside your existing PMS.
Offer true mobile check in and keys without losing the ability to host guests in person when it matters. Front office, housekeeping, and maintenance all work from the same calendar and access rules with a single source of truth in Calisto Ops or synced from your existing systems.
Replace key boxes and ad hoc PIN lists with digital keys tied to bookings and service visits. Owners can enjoy keyless access to their homes. Guests arrive on their own schedule. Your field teams and vendors get exactly the access they need when they need it, across multiple countries and brands.
Use digital keys for showings, inspections, and handovers while keeping full control over who can enter which property at each stage of the deal. When a listing becomes a managed home or a vacation rental, Calisto Key simply follows the property through its lifecycle.
Calisto Key is not just a nicer way to unlock doors. It is a way to align access with the promises you already make in Calisto One and the systems you already use. The result is safer, simpler, and easier to explain to guests and owners, with predictable per-lock pricing you can scale from a single home to a large hotel company.
Calisto Key starts around US$6 per lock per month on monthly terms, with a free trial so you can prove the workflows before you commit. Calisto Signal monitoring is included for every Calisto Key and Calisto Ops subscriber at no extra cost. When you are ready for after hours coverage, you can add Calisto 24·7 Monitoring and higher touch incident response without changing hardware or PMS.
No extra accounts and no mystery app. Guests see digital keys as a step in the journey they already started in Navigator. You decide whether they use wallet keys, app based keys, PINs, or a mix that matches your brand and hardware.
Front desk, guest services, and field staff stop managing physical keys and ad hoc spreadsheets. Access is created and revoked based on the bookings, tasks, and deals they are already managing in Calisto Ops, so they stay focused on hosting and service. If you start with Calisto Key alone, the same automations kick in as you connect more of your stack.
Every access decision is logged: who received which key, when it was valid, and which doors it opened. Combined with Signal alerts and Assure inspections, you can answer questions from owners, brands, insurers, or regulators with confidence.
Here are some of the most common questions from hotels, property managers, and real estate teams that are considering Calisto Key as their digital access layer, either on its own or inside Calisto One.
Calisto Key is priced per lock on monthly terms, starting around US$6 per lock per month with a free trial so you can validate the setup. Every Calisto Key subscription includes Calisto Signal monitoring at no additional cost, so you see access events and device health from day one. Calisto 24·7 Monitoring and higher-touch incident response are optional add-ons that you can activate per property or brand when you are ready for after hours coverage.
Calisto Key is a software layer and access brain, not a lock manufacturer. It connects to supported smart lock providers by API and to your Microsoft stack. It ties access to bookings, tasks, and deals so you are not locked into a single hardware vendor or a single PMS.
Calisto Key is designed to work with modern, API capable lock ecosystems that are used in hotels, vacation rentals, and multifamily properties. We start with your current or planned hardware stack and map out an integration path, then standardize the logic in CalistoOS so it feels consistent across brands and markets.
Not necessarily. Many teams choose wallet based keys or one tap links through Calisto Navigator so guests never need a separate app. If you prefer an app experience, Calisto Key can also power keys inside your branded guest app. The access logic is the same in both cases.
Yes. You can start with Calisto Key as a standalone access platform. Add reservations and visits manually, import them from CSV, or connect through our API or Power Automate. When you are ready, you can connect Calisto Key to Calisto One or swap PMS without losing your access history or rules.
When keys fail or guests call after hours, Calisto 24·7 and your internal teams see the booking, key status, and recent access history alongside Signal alerts. They can resend keys, issue temporary access, or dispatch help according to your playbooks with every action logged to the right property and stay in Calisto Ops.
Calisto Key is built to sit alongside Dynamics, Azure, Microsoft IoT Hub, and Power Platform. It uses CalistoOS as a shared data model, integrates with your existing tenant and security standards, and lets you keep analytics, automation, and identity in the tools your team already knows.
Yes. Most teams start Calisto Key with a single hotel, villa portfolio, or flagship property, then roll out to additional brands and markets once the playbooks are proven. Because Calisto Key runs on CalistoOS, your standards and integrations can scale without rebuilding from scratch.
