My house lock doesn't have an online mode. It has to be programmed by visiting physically, unlocking it, and then you have to stand there and touch it for a while in order to remove or activate a code. In other words, it only supports two features that a keyed lock doesn't:

1. a keyholder can't lose/forget the key 2. keys can be disabled without the expense of replacing the whole lock core

Since the purpose of a house lock is entirely a cultural/legal signal (you are allowed to come in / you do not have authority to come in) rather than security (if you are willing to damage the house, you can definitely enter), this is the perfect "smartness" for me.

The lockly model I have is the same, no cloud features.

You can configure it using the keypad or using an app over BT, that is the primary difference between it and a completely self contained device.
