I am not aware of any keypad zigbee or z-wave door lock that depends on that network to unlock in standard config. Yes, you could set it up that way, to unlock based on presence detection, etc, but that's on you. The standard setup is a local code list on the lock, with updates and status reported to home automation to enable integration. Most locks also have a standard key backup as well, so you're doubly protected.
