Hi @ClintonRH. I don’t have any information to share on the compatibility of the Kwikset 620 Locks, but you can see a list of the Z-Wave locks that are compatible with the Ring Alarm system in our Help Center Article here. You can also add your request for the Kwikset 620 to be compatible via our Feature Request board. This will help us to organize and share your requests with our teams here, as well as allow other neighbors to comment and add interest, all in one place.
