2) Turning the dial to the right, pass up the 2nd number once, then stop on it on the next round.
3) Turn the dial to the left directly to the 3rd number then stop.

Locksmiths agree If your safe doesn't have a key, skip Step 3.
Turn the dial to zero.
Insert your sentry safe key and turn it until the plunger pops out.
Turn the dial to the left (counterclockwise) three times to the first number of the combination (pass the first number of your combination two times, stopping on it the third time).
Turn the dial to the right (clockwise) two times to the second number of the combination (pass your second number once, stopping on it the second time).
Turn the dial to the left to the last number (stop the first time on your last number).
Pull the handle down; cracking the Fireproof Sentry Safe open.
