Opinion A: A strong thick door is the key I believe. When you have a thin and weak easy broken door, whatever lock you might use is meaningless.
Opinion B: Have you ever heard a theft break into a house by breaking the door ? Never, I suppose. So the lock is the real import for home protection."
Experts’ Opinion: Actually, both are key important. More exactly, the thickness of a metal frame door and a high grade lock cylinder with anti-broken protection will keep your house safe. The theft either try to unlock your lock, or try to broken the lock, so lock cylinder and its protection is extreamly important. Don’t buy lock that too cheap.
