I followed the directions to make my own combination of 7371. While that worked, I failed to then close the lock after I scrambled the combination. This is what you do on traditional locks like on lockers so people dont walk by and pop it off.
To actually lock this lock you have to be on your combination(in my case 7371) push down on the lock THEN scramble your combination. Because it took me so long to understand this, I gave the product a star less. I hope this helps somebody!
