/diy/ - Do It Yourself

>tldr; does the key hole under the dial locks the dial or is it an additional security after you dial the combination?

hello, is there anyone here who knows about safes? i have got pic related and I've been trying to find the combination. but the keyhole underneath it is bothering me. after searching google for safes with dials and keys, i found that the key is used, in most cases, to lock the dial. but I'm worried that could be something else: if it is used to lock the dial, then i don't have to worry about it, because it would already be unlocked. but if its not, i would have to try to lock pick it each time i try a combination and i wouldn't know if lockpicked it wrong or is the wrong combination

ps. if anyone have the model that would also be great, the only thing that could indicate the manufacturer is a torn and burned piece of paper in the back
