Align the Dials: Rotate the wheels to line up the current combination or 0-0-0-0 if it is brand new with the lock's alignment guide line.
Engage Reset Mode: Look closely at the side or the flat tip of the lock head for a small, recessed reset slot or button. Insert a small tool (such as a paperclip or a small flathead screwdriver) into this slot, press down, and turn it 90 degrees clockwise until it clicks into place.
Set the New Code: While the mechanism is in this reset position, rotate each of the four dials to your desired numbers.
Lock and Save: Insert your tool back into the reset slot and turn it 90 degrees counter-clockwise to pop it back out into its original orientation.
