Whether you're securing a building or a gangbox full of tools, a tough lock is essential. The Xena Bulletlock Padlock is made from high-grade stainless steel so it's resistant to bolt cutters, and it has a built-in 110-decibel siren triggered by shock and motion sensors. (If preferred, the siren can be de-activated.) According to the maker, the lock is pickproof and impervious to corrosion. The watch-style battery that powers the Bulletlock can last eight months before needing to be changed, says the company.
