Laura They are easy to break. As I mentioned in another topic, I would prefer an electronic lock
easier than a normal padlock with a key? i doubt it.
i think if it were designed securely, there would be a high demand, especially among people like us, because then the discussion about the emergency key would be solved.
Philip might be a good idea to change the combination lock every day of the year. That would take it above 4k years.
that's what my father would do, but i'm all about principle. i have an emergency system, but admittedly it could be better. with a number combination i would only have to send my father a whatsapp and he could give it to me within a minute.
