Replacement base station

I got a replacement base station today.  It was sent to me as an attempt to fix my issues with getting warnings about my smart locks.  I think that the issue is related to firmware and not to the base station, but whatever.  I'll try it.

They sent me no instructions at all on how to replace one base station with another, so I have no idea what to do.  Has anyone gone through this that can offer me some advice?
