Where to find your guest’s smart lock code

Smart lock code statuses and what they mean

You can find the status of your guest’s code on their reservation card in your Today tab. The statuses are:

• Door code shared: The code was successfully created and shared with your guest, but it’s not yet active because the reservation hasn’t started.
• Door code active at: Your guest checks in today, and their code activates at the check-in time.
• Door code active: The code is currently active.
• Backup door code active: Your guest has a backup code—these codes are always active until removed from the lock or until your lock comes back online.
• Door code pending: The code was created, but we’re waiting for it to sync with your lock. Your lock may be offline due to connectivity, battery, or other issues.
• No door code: Your lock was disconnected from Airbnb, so we were unable to create a code for this booking or the door code was removed. Learn more about smart lock statuses and how to resolve issues.

How guests’ codes are displayed in your smart lock app

Codes are displayed in your smart lock app with the guest’s reservation check-in date (month and day) and their first name. Each code also has a unique identifier at the end that’s used only for internal identification.

For example, 07/24 Brian xNSAgd.

The list of codes is sorted in order of the nearest check-in date to the furthest check-in date, and codes for past reservations are automatically removed from the list.

Note: If a guest’s first name contains any special characters, the name will show as “Guest.” The code can be identified by the reservation check-in date. For example, 07/24 Guest DEsDDf.

What you can change

Manually changing or deleting codes in your smart lock app

Guests’ codes are automatically generated and shared with them, and they can’t be changed or customized at this time. Important: Manually changing guests’ codes in your smart lock app won't change them on Airbnb. If you change a guest’s code in your smart lock app, it will temporarily show as updated and then revert back to the guest’s original code when it syncs with Airbnb.

Manually deleting guests’ codes in your smart lock app won't permanently delete them on Airbnb. If you manually delete a guest’s code in your smart lock app, a new code will be generated and shared with your guest on Airbnb. If you need to remove or change a guest’s code during their stay because of a safety or security issue, please reach out to our Community Support team.

Note: If your lock is offline and you manually change or delete a code in your smart lock app, a backup code may be shared with your guest if they’ve already checked in or their check-in is within 48 hours.

Changing a reservation’s check-in or checkout time

You can change the check-in and checkout times for individual reservations, and your guest's code will automatically update to be active during the times you select.

Find out how to adjust the check-in or checkout times for reservations.

Changing when codes expire after checkout

You can choose how long after checkout your guests’ codes expire to give them a little extra time to get out the door. When you add a connected smart lock to your listing, the default setting is for guests’ codes to expire 30 minutes after checkout. You can adjust this so that guests’ codes stay active from 15 minutes to 2 hours past your listing’s checkout time. Don’t worry: This extra time will never be shown to your guests.

Find the steps for adjusting when codes expire after checkout.

What happens to codes when reservations are canceled

When a reservation is canceled, the guest’s code is automatically removed from your smart lock, and they won’t be able to access your place with their code.

If a reservation is canceled while your smart lock is offline due to connectivity, battery, or other issues, we’ll remove the guest’s code as soon as your lock is back online. We’ll let you know right away that your lock is offline and provide you with info on how to resolve it as soon as possible.

What happens to codes when reservations are extended or shortened

When a reservation is changed (like extending the trip by a night), the guest’s code will automatically update so that it’s active for the new duration of their stay. Just make sure the changes are made as a trip change request on Airbnb so that the code is updated—trip change requests can be made by you as the Host or by your guest.

If we’re unable to reach your lock when a trip change is made, we may share a backup code with your guest to ensure they can access your place for the entire duration of their stay.

If you need to remove a guest’s code

Once a guest checks in, their code will remain active for the duration of their stay. You’re free to provide another code for your smart lock or an alternative way to access your place (ex: a physical key), but their code can still be used.

If you need to remove or change a guest’s code during their stay because of a safety or security issue, please reach out to our Community Support team.
