A door lock is not enough. You must also address the area around it. Extend your thinking about security measures to 18 and 24 inches around the lock itself. That is the area you must protect. A burglar doesn't care how much damage is caused by breaking into your home. The best locks in the world will do no good if a thief smashes in the door. A pinewood door frame will splinter and give way after a few savage kicks. A deadbolt can often be bypassed by simply breaking a window and reaching through to unlock it. Windows can be broken and locks undone. Many locked gates can be opened by simply reaching around and over. A hasp-and-lock will swiftly yield to blows from a even a small sledgehammer.
