If you have been granted Klevio keys for temporary access to a property of building, you might find yourself needing to change the validity of your keys, for example, if you extend your stay.
This can easily by done by the owner of the property, who can either issue new keys, or edit the 'valid from' and 'valid until' dates.
You will not be able to change the validity of these keys yourself (and nor will the Klevio support team), so please reach out to your host or the the person/company who shared the keys with you to make this change.
