Self check-in with smart locks has stopped being a competitive advantage and become a standard expectation among modern travelers.

More and more guests expect to arrive at their accommodation, open the door and go straight to their room — no queuing at reception, no waiting for anyone, no dependency on check-in hours.

For hoteliers and hosts, this represents a real opportunity: reduce operational workload, eliminate manual errors and deliver a modern experience — without expanding the team.

The MiniHotel and TTLock integration makes all of this possible, completely automatically. In this article we explain how the process works step by step, what you need to activate it, and why more and more properties are implementing it.

What is self check-in with smart locks?

Self check-in is a process that allows guests to complete their check-in autonomously, without any involvement from property staff. Through a digital form, the guest submits their details, verifies their identity and signs from their phone — before they even arrive.

When this process is combined with smart locks, the result is a fully contactless arrival: the guest receives a unique PIN code by email, enters it at the lock and goes straight to their room.

The benefits are concrete for both sides:

• For the guest: more autonomy, no waiting, access at any hour.
• For the property: less front desk pressure, remote management, cost reduction.
• For security: unique codes per booking, no physical keys to lose or copy.

How the MiniHotel and TTLock integration works

TTLock is the leading platform for smart lock management, compatible with hundreds of lock models from the world's top manufacturers. Its integration with MiniHotel connects the reservation system directly to the access system — without the hotelier needing to intervene at any point.

The full flow, from the moment a guest makes a booking to the moment they open their room door, works like this:

The most important thing about this flow: the hotelier doesn't intervene at any step. The booking enters the PMS, the system generates the code, sends it to the guest and revokes it automatically at check-out. Everything happens on its own.

What do you need to activate it?

The requirements to get the integration up and running are straightforward:

• An active MiniHotel PMS with the self check-in module enabled.
• TTLock-compatible smart locks. There is a wide variety of models available for all door types: guest rooms, main entrances and common areas.
• Connect the integration from the MiniHotel Marketplace. The setup process is guided and requires no technical knowledge.

Once configured, the system works autonomously for every booking, regardless of the source channel: Booking.com, Airbnb, Expedia, direct booking engine or any connected OTA.

The real impact on daily operations

Beyond the technology, what changes is the way you operate. Properties that implement self check-in with smart locks report concrete improvements:

• No front desk congestion during peak check-in hours.
• Ability to manage the property entirely remotely.
• Elimination of lost or duplicated key issues.
• Better guest experience, especially for late-night or last-minute arrivals.
• Digital log of every access, with a complete history per booking.

For properties with multiple units or across different locations, the advantage is even greater: a single centralized panel manages all access without needing to be physically present.

Automation you set up once and that works forever

The MiniHotel and TTLock integration is not just a technology feature — it's a shift in how a property operates. It means moving from a reactive model, where staff must be available for every arrival, to an automatic operation where the system does the work.

The guest arrives, enters their code and gets in. The hotelier does nothing. It's that simple.
