The response message:

The check-in time is invalid. This could be caused by the check-in time being in the past or the date and time set in Windows is wrong. Read more here:

Why this happens:

Some lock softwares have restrictions on the check-in date and time (starting time for the period validity) that can be encoded on a key card. If the reservation’s check-in time is too far in the past, the lock software can throw this error. This concept is similar to the Editable History Window in Mews, where the system does not allow for changes to be made for events/actions too far in the past.

If the same error appears multiple times in Device Commands Queue for different spaces, various reservations arriving today, and for different encoders, then it could be that the time zone set on your computer running the Mews Open API application is different from the time zone set in your door lock software and/or the computer running the door lock software server application.

NOTE: For more specific details on when a key card’s starting time is considered in the past for the particular door lock software used at your property, please contact the lock vendor to learn more.

How to resolve:

First check if the reservation for which you are trying to create a key card has an arrival time in the past.

If the reservation’s arrival time is today or within the lock software’s acceptable time window, yet this error continues to occur, check and ensure that the following have the same time zones:

  • Computer where the Mews Open API application is installed

  • Computer where the lock software server application is installed (if it is different from the computer above)

  • The lock software/management system itself

If the issue persists across different reservations, and the time zones are aligned across all systems and machines, then Mews recommends contacting your door lock software provider for further assistance.

Hint: for time conversion issues like these, it can be helpful to compare the key creation messages logged inside your door lock software against what is sent from Mews Open API.

Ask your lock vendor to help you retrieve system or event logs.
