No master code for dials. Either you know the combination, you have it manipulated or drilledI’ve seen some safes come with the dial combination written on the instruction sheet provided to the buyer and another safe company would ask you to create your own combination and they would set it up for you.
Either way would be wise to call a locksmith to reset the combination once it’s delivered.
Is there such a thing as a master combination code for the dials?
