text: how to open master lock? got the combination number but still dont know how to open. if it is a master combination like you put on your locker at school it will work like this.   13-2- 8    turn to the right a couple of times and stop on 13 then turn left and go past 2 and stop on 2 the second time then right to 8 and pull. i hope this helps. this is just an example not the combo.   "peace"
