I have 910 Z-Wave on my back door. I have a Leviton light switch for the garage lights about 2 feet away from the lock and it has never dropped off the network. These locks are Z-Wave, not Z-Wave Plus and have limited range. You could try a plug-in repeater near the lock and see if that helps. Also, not all repeaters work with locks. Here is one reference that might help.Z-Wave Repeaters for Z-Wave Locks
