Can't find what I need so have to ask....do you turn your lock all the way to the right in order to 2nd bolt the square shaped latch when you leave your house ?? Mine just does one simple turn to the left...when I try all the way to the right nothing happens...but surely its not designed that way? As in someone can reach in the letterbox and open handle if the second bolt doesn't work ? But I'm wondering does it even have that function

Is lock supposed to be flush on both sides. On your video it protrudes slightly on outside. But is flush on inside. We are trying to measure the lock cylinder length to buy now we have the handles and don't know if we should have it flush or not? Can you advise please

Are they , as good as ATS cylinder
