https://www.google.com/search?q=you...e..69i57j0.16862j0j7&sourceid=chrome&ie=UTF-8 Last time I checked (few years ago) it was very easy to open gun safes w/ electronic locks by using very strong magnets. I don't like it but I rent 3 very large SD boxes.
For smaller safes or lock boxes.....do they have boxes equipped with GPS or smartphone tracking so you can tell if it is being moved ? Sort of like the "Where Is My iPhone App" and similar locate apps ?
