Should I put a deadbolt on every door in the house, including interior ones?
Interior doors rarely need deadbolts unless there's a specific reason — like a home office, safe room, or accessory dwelling with a separate entry. The priority is every door that connects your home to the outside world, where a deadbolt provides the strongest single layer of mechanical protection.
