This is why I suggested a a keypad lock capable of user assign codes. Like @TylerDurden suggested the Schlage is a greate option specially combined with @RBoy app [RELEASE] Universal Enhanced Z-Wave Lock Driver for Schlage, Yale, Kwikset, IDLock, Popp, Danalock, August Pro, Keywe, Philia, Samsung
Worth exploring @DiasExtranyos !
