after recording the three numbers, apply a mathematical adjustment to each one individually: if a number is less than five, add five to it, but if it is greater than five, subtract five to find the correct combination.

try pushing the dial in the opposite direction of where it opens, then use a flashlight to peer into the gaps while rotating the tumbler to spot the small groove or notch on the shaft beneath each wheel.

once you identify the notch, carefully note the number it aligns with on the dial. you must repeat this process for all three wheels to get three specific numbers, taking care not to miss any shifts.
