There aren't many combinations to try if you have the odd hour.

That's what I meant by brute-forcing it: I tried all the combinations.

Outside, in the winter: I probably didn't key in the right one correctly
and missed it.

There are only 2^10 combinations on the push button one (1023).
Even less if you assume they have left it with the four button combination
they come with (210 IMMIC).
But you would need some basic maths and to have some idea of how they work,
maybe a child of five to help?

I doubt if a normal lock has that many differs so its not less secure.
