Have a lock through the winter outdoors used to an unprotected location, the other for the basement door. The keys are very simplistic, but I think anyone who wants to leave as a castle, is not just fix the locking mechanism, but it crack with bolt cutters or similar simple. Because the locks act massively, protect as good as their more expensive siblings. So I do not values from it. When used outdoors have to walk oils every 2 months to keep it smooth. But I could find no rust. I did not expect at this price. The castle interior works after almost a year without care still properly and smoothly. The keys are pretty small, and it is great when you have a key to all the locks - intended especially if have multiple access.
