Its adjustable shackle fits securely on most types of door hardware—including lever, ball, biscuit, and tulip style handles—making it a practical solution for managing spare keys safely without carrying them or hiding them around your property.
This durable lock box solves the problem of managing spare keys securely. The 5420D lets you set your own combination code and store multiple keys in a compact, weather-resistant metal enclosure. The vinyl-coated shackle and molded bumper protect your door finish from scratches, while a weatherproof cover helps prevent freezing and jamming in harsh outdoor conditions.
