There may be other specific error messages.

How to resolve:

Mews recommends first checking whether the reservation for which you are trying to create a key card has a departure date that is in the past or today.

Then try to create the key again with a new key card.

If the above does not work, Mews recommend contacting Assa Abloy for assistance.

When contacting your vendor’s support, we recommend including the error message you saw. If needed, you can also provide them with Mews Connector logs from that day.
