The safe has a factory set combo and instructions for setting it yourself so a po could have changed it.
Also of note the wheels may get gummy so be sure lock cover is opened up and all is well when open.
Two marks on front but one is real and other is pointer.
Sile combo to left marker then after last number is on left marker turn towards right marker to unlatch...at least that is how ours works.
