A:Answer You can set it to lock after the door closes and you can tell it how many seconds to wait (30 sec, 1 min, 5 min). You can also set what it does in each mode. Home and Away modes can lock it or do nothing, Off mode can unlock from home, unlock from away, unlock it always, or do nothing. There's no setting to lock it based on time, but if you turn your alarm on at night it can lock it then.
