People who are just starting to rent out accommodation often ask what self check-in is and what the process looks like from a guest’s perspective. In the simplest terms, it means being able to enter an apartment independently, without meeting the host or a member of the reception staff. The process begins when the reservation is made and ends only when access to the property expires.
A well-designed self check-in process is not limited to leaving a key in a lockbox. The guest should receive clear instructions, an access code that works at the right time, and contact details for someone who can help if a problem occurs. The owner, in turn, needs to choose the right device, configure it correctly, and prepare an emergency procedure.
Self check-in: what is it?
Self check-in allows a guest to enter a property without face-to-face contact with staff. Access can be provided with a physical key placed in a lockbox, an individual PIN code, or an electronic lock connected to a reservation system.
This does not mean giving up guest service. The owner is still responsible for preparing the apartment, providing instructions, and helping in the event of a problem. If you want to connect the process with the information stored in the reservation, you can use self check-in in IdoBooking, which supports automated delivery of access details to the property.
Self check-in vs. online registration
An online registration form and self check-in are not the same thing. The form is used to collect guest details, information required by the property, and acceptance of the house rules. Completing it does not open the apartment door. The guest still needs to receive a key, PIN code, or access to an electronic lock.
In a traditional model, formalities and key handover take place during a meeting with staff. With self check-in, both stages can be handled remotely and almost at the same time, but each requires separate configuration.
How does contactless check-in work step by step?
The entire process can be divided into several stages.
- Everything starts when the reservation is made. Information about the apartment, guest, and stay dates is sent to the system.
- Based on the reservation data, an access code can be created or assigned. It becomes active at a specified time on the day of arrival.
- The guest receives the code together with instructions by email or SMS shortly before arrival. If the stay dates or arrival time change, the period during which the code is active should also be updated.
- After check-out, access expires so the previous guest can no longer enter the apartment.
The exact process depends on the type of lock and the scope of its integration with the reservation system.
Key lockbox, electronic lock, or PIN code?
A key lockbox is a relatively simple way to provide access. It does not require replacing the door lock, but there is still a physical key inside that can be lost or copied. If the owner does not change the lockbox code for a long time, previous guests may still know it.
An electronic lock with a PIN code makes it possible to assign access to a specific reservation. An individual code can work only from the check-in time until check-out. Such a device requires installation, configuration, and power monitoring. When comparing electronic locks and access codes, it is worth considering how the system works in an emergency, not only how convenient it is in everyday use.
What information should the guest receive?
A message containing only the code is not enough if the guest does not know which door to use it on. The instructions should include the exact address, apartment number, time when access becomes active, and directions from the building entrance. Information about the intercom, floor, parking space, and check-out rules can also be useful.
It is best to arrange the instructions in the same order in which the guest will perform the individual steps. A photo of the gate or a distinctive landmark near the entrance, such as a shop, monument, or large sign, can make it easier to find the correct entrance after dark. The guest should also receive a contact number in case of problems and instructions in a language they understand.
Benefits of self check-in for the owner and guest
The guest does not need to arrange a time to collect keys or notify the host about every delay. They can enter the property while the code is active, including late in the evening or at night. This gives them more freedom, while they should still have access to support if needed.
For the owner, self check-in means:
- less travel and planning;
- fewer meetings related to handing over keys;
- easier management of arrivals taking place at similar times when several apartments are involved;
- easier handling of arrivals outside standard hours, for example after 10 p.m.
The most common problems with contactless check-in
The code may be incorrect, inactive, or assigned to another apartment. Problems can also result from a discharged lock battery, lack of an internet connection, or a change to the phone number that was supposed to receive the message. Sometimes the device itself works correctly, but the guest cannot find the entrance or does not know how to operate the lock.
These situations can be reduced through advance testing, battery monitoring, and checking the status of sent messages. After every reservation modification, make sure that the code and its active period have also been updated. The instructions should be short, clear, and adapted to the layout of the specific building and the characteristics of the device.
Emergency procedure
Before launching self check-in, the owner should decide who will handle reports outside standard working hours. The person on duty needs access to reservation data and should be able to verify the code, change permissions, or provide the guest with further instructions. The emergency plan may include a spare key stored in a secure place, an additional code, or assistance from a staff member located nearby. The way to enter the property during a device failure depends on the lock model, so it should be agreed with the supplier before installation.
How do you connect self check-in with a reservation system?
Manually creating codes, copying reservation details, and sending every message separately reduces the benefits of automation. With a larger number of properties, it is easy to confuse stay dates or leave access active after check-out.
Connecting a lock with the reservation system makes it possible to use information already stored in the booking. IdoBooking offers integrations with access control systems that can create codes based on stay dates and send them to guests through automated messages.
IdoBooking integrations with electronic lock systems
An integration connects a specific apartment and lock with the reservation stored in the system. This allows the code to be assigned to the correct property and remain active only during the specified period. Depending on the partner, changing the stay dates may also automatically update the access details.
The scope of available functions is not identical in every solution. Differences may concern code handling after a reservation change, offline operation, the mobile app, and emergency door opening. Before choosing a system, you should therefore check both the integration features and the technical specifications of the particular device.
TTLock, SetPin, RentingLock, and PINMaster
IdoBooking works with several electronic lock systems. All of them allow access to be provided without meeting the guest in person, but they differ in configuration and the scope of automation. The solution should be matched to the door construction, number of properties, internet availability, and the ability to provide technical support.
| Solution | Access method | Automatic codes | Update after reservation change | Active period | Internet | Guest app | Emergency entry | Property type |
| TTLock | lock access code | yes | yes; real-time updates apply to the online version | matches the stay period | depends on whether the lock works online or offline | not required when entering with a code | depends on the model | apartments and distributed properties |
| SetPin | lock access code | yes | can be changed manually from the hotel system | reservation period | remote functions depend on configuration | not required when entering with a code | no information provided on the website | apartments and small properties |
| RentingLock | PIN code | yes | yes, after a change of stay dates or arrival time | reservation period | the code works without internet access on the lock side | no | depends on configuration | distributed properties and properties without a reception desk |
| PINMaster | five-digit PIN code | yes | yes, after a change of stay dates or arrival time | reservation period | the lock can operate without internet or GSM | no | physical key | apartments, holiday cottages, and small guesthouses |
Owners using TTLock-compatible locks can activate the TTLock integration and manage codes based on reservations stored in IdoBooking. In the online version, changes are updated in real time. With offline locks, deleting a code after a cancellation may require using the TTLock app.
The SetPin integration allows you to generate and delete codes for compatible locks and assign them to the stay period. The owner can manage access from the IdoBooking panel or the provider’s app.
The RentingLock integration also connects the lock with reservations. A code is generated automatically, and after a change to the stay dates or arrival time it can be updated and sent to the guest again. The guest does not need an app to enter the code.
The PINMaster integration creates temporary codes for the brand’s locks based on reservation data and sends them through the configured channel. The lock can work without internet access or a GSM network, while in an emergency the door can be opened with a physical key.
Which properties benefit most from self check-in?
Self check-in is well suited to apartments, holiday cottages, villas, and small guesthouses without a 24-hour reception desk. It also makes it easier to manage properties spread across different locations, where handing over keys in person would require frequent travel.
A property that uses self check-in does not have to give up on-site support entirely. In buildings with a complicated layout, frequent group stays, or guests who may need assistance, self check-in can be combined with staff support during selected hours.
Self check-in implementation checklist
The implementation of self check-in should start with checking the technical conditions at the property. The type of door, access to power and internet, and the number of properties being managed all affect the choice of device. Before making the solution available to guests, the entire process should also be tested, from code generation and delivery to automatic expiration of access.
- choose a device that fits the door construction;
- determine the installation and power supply method;
- configure temporary access codes;
- connect the lock with the reservation system;
- prepare email and SMS messages;
- create an emergency procedure;
- test the code, its modification, and expiration;
- prepare entry instructions for the guest;
- create separate access for cleaning and maintenance staff.
FAQ
Does self check-in mean there is no contact with staff?
No. The guest checks in and out independently, but they should still be able to contact the owner or a person on duty quickly.
Does a key lockbox provide the same level of control as a temporary code?
No. A key can be lost or copied, and the lockbox code may be known to previous guests. An individual code makes it possible to limit access to the duration of the stay.
Does the guest need to install an app?
It depends on the selected solution. In the configurations described above, the guest can enter using a code without installing an app, but the requirements should always be confirmed for the specific device.
What happens when the reservation dates change?
The system may update the code or its active period. The exact process depends on the partner, lock model, and integration configuration.
Does self check-in work without internet access?
Some locks support offline codes, but remote management may require an internet connection or an additional device. The technical requirements should be checked before installation. Owners who want to combine independent entry with automated reservation management can use self check-in in IdoBooking. Before implementation, it is worth comparing integrations with TTLock, SetPin, RentingLock, and PINMaster, taking into account the door construction, connectivity, and emergency procedures.
Information about partner integrations and features is current as of August 19, 2026. The availability of individual options depends on the device model and technical configuration.
