I am pretty sure there are smart locks that don't rely on an active connection to the cloud. The lock downloads keys when it has a connection and a smartphone can download keys. This means they work even if no active internet connection at the time the person tries to open. If the connection was dead the entire time between creating the new key and the person trying to use the lock it still wouldn't work.
If there are not locks that work this way it sure seems like there should be. Using cloud services to enable cool features is great. But if those services are not designed from the beginning with fallback for when the internet/cloud isn't live that is something that is a weakness that often is unwise to leave in place imo.
