You need to make sure that the device has been fully interviewed before anything properly.
I do know that with one lock that I’ve got at the edge of the network I have a lot of issues trying to program or trigger state changes on it. I’m working on getting another zwave router in between that and the controller to fix the problem.
What you might try to do is bring the device close by again (if you’ve already put it back where it needs to be). While it’s close to whatever router you used to get it included, validate that it can unlock / lock while it’s nearby. If you’re planning on using Keymaster now would also be the best time to make sure it gets configured so you can get some codes into the lock.
