Standard US doors that pass Yale's printed door checker
A keypad deadbolt with a removable Wi-Fi module, unlimited scheduled codes, Auto-Unlock and a DoorSense sensor that keeps Auto-Lock from throwing the bolt on an open door. It keeps a mechanical key. Two things to settle first: the Wi-Fi band, and whether your door passes Yale's own Door Checker.
