Just for completeness, there is a DTH that works with the Monoprice locks and it allows you to program codes on the locks using a SmartApp like SmartThings SmartLocks or Lock User Management (LUM).
However do note that the lock has an quirk with the firmware and doesn’t always report which user operated the lock. So while you can program codes and have users unlock the lock, it won’t always say which user unlocked it. YMMV
