Home security doesn’t always need to involve complicated technology. Many older homeowners remember a time when people relied on simple, practical ways to protect their property—locking doors, keeping lights on at night, and staying alert to their surroundings. The aluminum foil door handle method fits right into that tradition: it’s easy, it costs almost nothing, and it adds a surprising layer of protection.
The concept is straightforward. Before heading to bed or leaving your house for the day, wrap a piece of aluminum foil snugly around your outside door handle. Smooth it out gently so there are no big wrinkles or loose edges. When you return or wake up the next morning, take a quick look. If you notice that the foil is bent, torn, or crinkled in new ways, that could be a sign someone tried to touch or turn your handle.
