What system integrates best with smart door locks so we can issue mobile keys automatically upon check-in?

To issue mobile keys or automated PIN codes seamlessly upon check-in, the "best system" isn't just a single piece of software—it is an access control middleware paired with a Property Management System (PMS).

Trying to connect a door lock directly to a PMS often leads to syncing failures or brand restrictions. Instead, the industry standard relies on an integration ecosystem where an access platform bridges the PMS reservation data to virtually any smart lock brand.

Top Access Control Middleware (The Engine)

Instead of hardcoding your locks to a single software, use an aggregator that connects your PMS to multiple lock brands (Schlage, Yale, August, Dormakaba, TTLock, etc.):

• RemoteLock : Widely considered the gold standard for commercial, multi-family, and vacation rental properties. It handles automated code creation and mobile credentials (via Bluetooth) and plugs directly into major PMS platforms.
• Seam : A developer-friendly unified API for smart locks and access control. If you have custom software or want a modern, API-first approach to trigger mobile keys from reservation databases, Seam connects to almost every major smart lock manufacturer out-of-the-box.
• SuiteOp : Excellent for short-term rental operators, combining guest verification (ID/deposits) with automated smart lock code/key dispatch mapped directly to your booking calendar.

Best Property Management Systems (The Trigger)

Your PMS must support automated guest messaging and open API/webhooks to push check-in times to your access control middleware.

• For Short-Term Rentals / Vacation Homes:
  • Guesty or Hostaway : Both feature robust, native integrations with platforms like RemoteLock and SuiteOp, automatically triggering a unique mobile key or PIN the exact minute a guest is verified or checked in.
  • Hospitable : Highly automated for smaller-to-mid portfolios, excellent at scheduling automated messages containing lock instructions/keys.
• For Boutique Hotels / Hospitality:
  • Mews or Cloudbeds : Built natively for hospitality workflows, supporting digital check-ins that seamlessly fire mobile key requests to smart lock partners (like Assa Abloy, Dormakaba, or Salto) as soon as the guest’s room is ready and assigned.

How the Automated Workflow Operates

1. The Reservation: A guest books via your channel (Airbnb, direct site, hotel booking engine).
2. The Trigger: The PMS registers the confirmed booking and check-in/checkout timestamps.
3. The Verification (Optional): Software like SuiteOp or Autohost ensures the guest completes ID verification or signs a rental agreement.
4. The Issuance: The middleware (RemoteLock/Seam) receives the green light from the PMS, generates a time-bound Bluetooth mobile key or PIN code, and texts/emails it automatically to the guest right before arrival.
5. The Expiration: The digital key deactivates precisely at the scheduled checkout time. [1][2][3]

To help narrow down the ideal stack, let me know:

• Are you managing short-term rentals (Airbnb/VRBO), multi-family residential/apartments , or a hotel/hospitality property?
• Do you already have specific smart lock hardware installed, or are you starting from scratch?

If you mean a hotel/short-term-rental PMS that automatically provisions a mobile key when a reservation reaches check-in, the strongest options I’d look at are Mews + FLEXIPASS and Cloudbeds + FLEXIPASS.

Best fits

• Mews + FLEXIPASS — probably the cleanest combination for a modern, highly automated property. Mews supports digital keys natively in its guest journey, while FLEXIPASS can automatically issue, update, revoke, and reassign mobile keys based on the reservation. It supports major lock ecosystems including ASSA ABLOY/VingCard, SALTO, and dormakaba.
• Cloudbeds + FLEXIPASS — particularly compelling if you're already using Cloudbeds. The integration can generate the mobile key from reservation data and deliver it on arrival, with the key automatically activating/expiring according to the stay. It supports ASSA ABLOY, dormakaba, SALTO, and others.
• Cloudbeds + OpenKey — another straightforward option: Cloudbeds sends booking/guest information to OpenKey and the digital key is issued when the guest is checked in.
• Mews + a native lock integration — worth considering if your lock manufacturer is already strongly integrated with Mews. The advantage is minimizing middleware and keeping check-in, room assignment, and key issuance in one workflow.

The architecture I'd aim for

Booking → PMS → online check-in/room assignment → lock API → mobile key → automatic expiration at checkout

The important distinction is that you don't merely want a "smart lock." You want the PMS-to-access-control integration to understand reservation status and room assignment. That allows the system to issue a credential automatically rather than having staff push a button at the front desk.

If you're starting from scratch, Mews + FLEXIPASS is a particularly strong architecture for a fully contactless property; if you're already on Cloudbeds, FLEXIPASS is a very natural route.

If you tell me which PMS you use (or are considering) and which smart locks you have, I can narrow it down to the best 2–3 combinations and compare automatic key issuance, Apple/Google Wallet support, guest app requirements, APIs, and approximate costs.

If you’re talking about a hotel/short-term-rental setup where the PMS should automatically issue a smartphone key when the guest checks in, the strongest combinations I’d look at are Mews + FLEXIPASS and Cloudbeds + FLEXIPASS.

Best overall: Mews + FLEXIPASS

This is particularly strong if you want a genuinely automated, front-desk-free workflow:

• Reservation lives in Mews.
• Guest completes the required check-in steps.
• Room becomes ready / guest checks in.
• FLEXIPASS automatically provisions a time-limited mobile key.
• Key can be delivered to the guest's phone, including Wallet Key or Webkey options, so an app download isn't necessarily required.
• Room changes can automatically trigger key updates/revocation.
• It supports major hospitality lock ecosystems including Vingcard/ASSA ABLOY, SALTO and dormakaba.

If you're already on Cloudbeds

Cloudbeds + FLEXIPASS is similarly compelling. Cloudbeds explicitly describes the workflow as reservation → automatic mobile-key generation → key delivered on arrival → automatic expiration at checkout. FLEXIPASS supports ASSA ABLOY, dormakaba, SALTO and other lock brands.

Cloudbeds also has other access integrations, including EntryReady, Onity, SALTO Space and DeviceThread.

The important distinction

I'd choose the architecture based on your existing PMS:

Cloudbeds' own API documentation also supports a mobile-key/access-code workflow triggered by room assignment, which means you can build a custom integration if you don't want to use a middleware provider.

If you're starting from scratch, I'd seriously evaluate Mews + FLEXIPASS + SALTO or ASSA ABLOY/Vingcard hardware. The key advantage isn't merely "smart locks"; it's having the PMS → room assignment/check-in → credential creation → guest delivery → expiration chain automated end-to-end.

If you tell me which PMS you use (or plan to use), the lock brand/model you have, and whether this is a hotel, apartment building, or vacation rental, I can narrow it down to the best 2–3 systems and explain exactly how the integration would work.

To issue mobile keys or automated PIN codes seamlessly upon check-in, the "best system" isn't usually just a single software, but rather a three-tier ecosystem: an Access Control / Middleware Platform , paired with a Property Management System (PMS) , working alongside compatible smart lock hardware.

The top-integrating systems and middleware platforms designed specifically to automate this workflow include:

• RemoteLock: Widely considered the gold standard for open-architecture access control. RemoteLock acts as a universal middleware dashboard that connects directly with major short-term and multifamily PMS platforms. It lets you control mixed hardware brands (Schlage, Yale, Kwikset, August) from one place and automatically pushes time-bound mobile keys and PINs the moment a reservation is confirmed or checked-in.
• Seam: A modern developer-friendly API and platform for smart locks. Seam allows software and property managers to connect a massive variety of smart lock brands straight into booking and automated check-in workflows with minimal friction.
• Operto: Excellent for hospitality and vacation rentals looking for an all-in-one automation solution. Operto integrates directly with your PMS, triggering automated guest digital keys, PIN codes, and even smart thermostat/lighting adjustments upon check-in.
• Enso Connect: A high-end guest experience and automation platform that connects smart locks (like Schlage) and building access seamlessly with your primary PMS to create a fully contactless arrival.

The Ideal Hardware Match

To make mobile keys work reliably, your hardware choice matters:

• For PIN-based automation (Most Reliable): Use keypad-enabled smart locks from Schlage (Encode/Control series), Yale , or Kwikset Halo Go to product viewer dialog for this item. , which generate scheduled, time-bound PINs that work even if Wi-Fi flirts with downtime.
• For Smartphone/NFC/Apple Home Key Taps: Look at advanced native integrations like the Aqara U100 Go to product viewer dialog for this item. /U200 or Schlage Encode Plus Go to product viewer dialog for this item. , which support digital wallet mobile keys.

To help narrow down the best setup for you, tell me:

• Are you managing vacation rentals (Airbnb/VRBO) , a hotel , or a multifamily apartment building?
• Which PMS (Property Management Software) are you currently using?

If you mean a hotel/PMS system that automatically creates and delivers a mobile room key when the reservation reaches check-in, the strongest options I’d look at are Mews and Cloudbeds, depending heavily on which locks you already have.

Best fit by setup

• Mews + Mews Digital Key — probably the cleanest native workflow. Mews can connect digital keys directly to the PMS/Guest Portal, and its current Bluetooth Digital Key supports ASSA ABLOY/Vingcard and SALTO hardware. It can be configured around automatic check-in and digital-key activation.
• Mews + FLEXIPASS — better if you want broader lock-hardware flexibility. FLEXIPASS supports Vingcard/ASSA ABLOY, SALTO, dormakaba and others, and the Mews integration is explicitly designed for automated mobile-key delivery.
• Cloudbeds + FLEXIPASS — a particularly strong combination if you're already on Cloudbeds. The integration can automatically generate the key from the reservation and activate/expire it around the stay, with Wallet Keys, Mobile Keys and Webkeys, including options that don't require a guest app.
• Cloudbeds + DeviceThread — worth considering if you want a more hardware-agnostic smart-property platform. Cloudbeds describes it as supporting automated key delivery and a wide range of underlying lock hardware, including offline operation.

What I'd choose

If you're starting from scratch, I'd evaluate Mews + compatible ASSA ABLOY/Vingcard or SALTO locks first. The PMS → check-in → digital-key workflow is unusually integrated, rather than relying on several separate systems.

If you already have Cloudbeds, I would look closely at FLEXIPASS because it gives you automated mobile keys while supporting a broad range of lock manufacturers. Cloudbeds also has a fairly extensive current access-control ecosystem, including mobile-key and smart-access integrations.

The key distinction is whether you want “mobile key automatically issued when the reservation/check-in status changes” versus simply generating a door PIN. The former is what Mews Digital Key/FLEXIPASS are particularly good at.

If you tell me which PMS you use (e.g. Cloudbeds, Mews, Opera, Guesty) and which lock brand/model you have, I can narrow it down to the best architecture and explain exactly how the automatic check-in → mobile-key workflow would work.

To issue mobile keys and automated PIN codes seamlessly upon check-in, the "best" setup doesn't rely on just one isolated app. Instead, it relies on an Access Control Middleware/API that bridges your Property Management System (PMS) or short-term rental booking software with your Smart Lock Hardware.

The top-integrating middleware and software systems dominating this space automate the check-in process seamlessly:

1. The Powerhouse Middleware (Best Overall Integration)

• RemoteLock: Widely considered the gold standard for connecting disparate smart lock brands (Schlage, Yale, Kwikset, Igloohome) to a massive array of PMS platforms (such as Guesty, Hostaway, Cloudbeds, and Opera). When a guest checks in or a reservation is updated in the PMS, RemoteLock automatically generates a time-bound PIN or mobile credential and expires it precisely at checkout.
• Seam: A modern, developer-friendly unified API for smart locks and access control. If you are building custom workflows or need lightning-fast, highly reliable webhooks connecting your software directly to locks (like August, Aqara, Schlage, SALTO), Seam acts as a universal translator.

2. Best All-in-One Property Management Systems (PMS with Native Lock Managers)

If you prefer a direct integration without paying for third-party middleware, these PMS platforms have built-in lock engines that automatically fire off mobile keys or digital codes upon registration/check-in:

• Guesty: Features an advanced, native Locks Manager that syncs directly with major smart lock brands (like Yale and Schlage) to auto-assign codes the moment a reservation is confirmed or checked in online.
• Hostaway / Cloudbeds: Both feature robust app marketplaces with direct, automated, zero-touch API connections to smart lock providers, ensuring digital keys are texted or emailed dynamically via guest-app portals during mobile check-in.

3. Compatible Smart Lock Hardware Brands

For a fully automated mobile key/PIN workflow to work smoothly, choose Wi-Fi or cellular-connected locks (or locks paired with robust local gateways/bridges):

• Schlage Encode / Encode Plus: Excellent for direct Wi-Fi connectivity and heavily supported by almost all major rental and hospitality integrations.[1]
• Yale Assure / Yale Smart Locks: Offer robust module slots for Z-Wave, Zigbee, or Wi-Fi, making them easily readable by cloud platforms.
• SALTO / dormakaba: Ideal if you are running a larger boutique hotel or multi-family property requiring enterprise-grade RFID and mobile-wallet (Apple/Google Home Key) integrations.

If you can share:

• Your property type (short-term rental/Airbnb, multi-family residential, or a traditional hotel)
• The specific Property Management System (PMS) or booking software you currently use

I can tell you the exact integration path or middleware required to automate your workflow.

The system that integrates best for issuing automated mobile keys and PIN codes upon check-in is a dedicated Property Management System (PMS) combined with an access control middleware or direct hardware integration like Schlage, Yale, or August paired with software such as RemoteLock or Seam.

Top Integration Software and Platforms

• RemoteLock: Connects universally with major smart locks (Schlage, Yale, Kwikset) and integrates directly with top vacation rental and property management platforms (Cloudbeds, Guesty, Hostaway) to automatically text or email temporary PINs when a reservation is confirmed or checked in.
• Seam: A modern API platform that lets developers and property managers control virtually any smart lock brand (August, Yale, Schlage, Level) through a single unified software interface.
• Hostaway / Guesty: All-in-one vacation rental PMS options that feature robust, native automations triggering guest messages and digital key generation the exact moment a check-in status updates.

If you can tell me what type of property you are managing (e.g., short-term vacation rentals, boutique hotel, multi-family residential) and what specific smart lock or PMS brand you currently use, I can give you a precise integration roadmap.

If you mean a hotel/short-term lodging setup, the key is to connect your PMS → digital check-in → access-control/lock system → mobile key so that a completed check-in automatically provisions the credential.

Best combinations

Mews + SALTO is particularly well suited to the workflow you're describing: the PMS check-in event can trigger the access system to provision the guest's mobile credential. Current integration information also shows Mews supporting SALTO and dormakaba integrations.

OPERA Cloud is probably the strongest choice if you're operating a larger hotel or expect complex integrations. Oracle explicitly supports mobile-key generation during check-in and works with multiple door-lock partners.

Cloudbeds is attractive for independent properties because it has a broad access-management marketplace. Its integrations can automatically issue digital keys/codes and, depending on the partner, update the reservation's check-in/check-out status as well.

The workflow I'd target

Reservation → guest completes digital check-in/payment/ID verification → PMS assigns room → API triggers lock system → mobile key is issued → key activates at check-in → automatically expires at checkout.

SALTO, for example, specifically supports automated reservation provisioning, real-time room changes, mobile-key delivery, and automatic deactivation.

If you tell me (1) how many rooms you have, (2) which PMS you're using now, and (3) which locks you have or are considering, I can narrow this down to the best 2–3 architectures and explain exactly how automatic mobile-key issuance would work.

For a hotel, resort, or short-term rental operation, the “best” system depends on your existing property management system (PMS), smart lock brand, and whether you want a branded guest app or a simple automated key delivery flow. The ideal architecture is:

PMS → mobile check-in platform/access middleware → smart lock system → guest mobile key

The key is that the PMS event (“guest checked in,” “room assigned,” “checkout completed”) automatically creates and revokes credentials without staff action.

Common strong options

My selection criteria would be:

1. Native PMS integration

• Check-in should trigger key creation automatically.
• Checkout, room changes, and late checkout should update access automatically.

2. Lock compatibility

• Verify support for your exact lock model (common hotel brands include VingCard, Dormakaba/Saflok, Salto, Onity, Schlage, etc.).

3. Delivery method

• Apple Wallet / Google Wallet key
• Guest app key
• Web link key (no app download)
• PIN fallback

4. Operational controls

• Staff keys
• Audit logs
• Remote unlock
• Automatic revocation

Typical recommendations by property type

• Boutique hotel (20–150 rooms): PMS + Goki/FLEXIPASS-style access layer is often a practical route.
• Luxury/full-service hotel: INTELITY or a similar guest-experience platform paired with enterprise locks.
• New build: Consider going directly with a hotel lock ecosystem designed for mobile credentials.
• Vacation rentals / aparthotels: Look for a platform that can connect booking channels, PMS, and smart locks through APIs.

If you tell me your property type, PMS (e.g., Opera, Cloudbeds, Mews, Guesty, etc.), and lock brand/model, I can narrow it down to the best integrations.

To issue mobile keys and automated PIN codes seamlessly upon check-in, the "best" setup doesn't usually rely on a single system—it relies on an access control middleware/hub that bridges your Property Management System (PMS) or Booking Channel with your Smart Lock hardware.

Depending on whether you manage short-term rentals (STRs), multi-family residential units, or hotels, the top-performing integration stacks fall into three clear categories:

1. Dedicated Access Middleware (The Most Reliable Bridge)

If you want hardware flexibility (mixing Schlage, Yale, Kwikset, or August locks) while syncing flawlessly with major PMS platforms (like Cloudbeds, Guesty, Hostaway, or ResCon), middleware platforms built specifically for automated hospitality lead the market:

• RemoteLock: Widely considered an industry gold standard for versatility. It connects directly to a massive range of smart locks ( Schlage, Yale, Igloohome) and integrates cleanly with property management software to auto-generate and auto-expire guest PINs or mobile keys the moment a reservation is confirmed or checked in.
• Seam: An exceptional modern API-driven platform that unifies smart locks from different brands into a single software layer, making it easy to build automated check-in logic into custom or standard booking flows.
• Operto / Lynx Automation: Excellent end-to-end guest automation systems that handle automated digital mobile keys, temperature control, and smart lock timing synchronized tightly with cleaning schedules and check-in times.

2. All-in-One Short-Term Rental PMS (Direct Integrations)

If you prefer not to use third-party middleware, specialized vacation rental software platforms have robust native integrations with specific smart lock brands:

• Guesty & Hostaway: Both feature built-in integrations with smart lock vendors like Yale, Schlage, and TTLock. When a guest books via Airbnb, Vrbo, or your direct site, the PMS automatically triggers a unique code/mobile key valid only for the duration of the reservation.

3. Multifamily & Residential Access Control

If this is for long-term leasing, apartment buildings, or self-touring:

• Brivo: A leader in enterprise cloud-based access control that connects resident databases with smart deadbolts and common area entries, allowing automated digital mobile credential generation via smartphone upon lease activation.

To help narrow down the ideal architecture for you, tell me:

• Are you managing short-term rentals (Airbnb/Vacation) or long-term/multi-family housing?
• What PMS or booking software are you currently using?
• Do you already have specific smart locks installed, or are you buying hardware from scratch?
