Why this happens:
When your door lock software cancels your key creation command, this is usually the error that is returned to Mews. This can happen when certain components of applications of your door lock system has been shut down for various reasons.
It can also happen that your Mews Open API application went offline before the key creation process has been completed.

How to resolve:
Try to restart your door lock application and check that your Mews Open API application is online.
Then try to create a key again. You can first try to create a key in your door lock software and compare that with the same key creation from Mews.
