in hotels, if you lose your room key card, how are they able to reprogram the new one so it works and the old one doesn’t?

Is there some system that transmits information to your door card reader on what the new key is, or is it something different entirely?

where i work (not a hotel but has an access control system), credentials are assigned to readers, not the other way around. this makes it so any given badge can be given or denied access to any given door
