I know it's not a computer, but it's electric and I can't figure it out. I just took posession of a firesafe, it was free, trick was... They don't know the combo. It's from the early 90's, from Hyundai. It has dual dead bolts (one going up and one going down), and the hinge bolts do not come off. I can't find a single piece of information about it via the web, Hyundai, nor Sams (where it was originally purchased) I know the code has to be 6 alphanumeric characters in length (0 - 9, A - F). Other than directing me to a locksmith, anyone have any suggestions?
