anyway i had a few laying around(cheap ones) and i could open them with a paperclip..
The ones with combinations require no skill

a 4 number index : x y w z has 10 000 solutions

x = {0;1;2;3;4;5;6;7;8;9} and each one of the elements has 999 solutions on the following position. But there's one missing, the 000 one..
So : 999 x 10 + 10 (the ten 000 possible ones) = 9990 + 10 = 10 000 ..You've got to try 10000 combinations on a 4 positions-lock if you desperatly want to open it
