Your Master Lock built-in combination lock includes 5 selectable combinations. These combinations are listed on the control chart that was provided with your locking system. This video demonstrates the procedure for changing combinations from the current in-use combination to the next combination in the series. Insert the key and turn to the key to the right, or clockwise, until it stops. Move the dial to 0. Push the button on the back. While pushing the button, move the dial clockwise 2 marks, from 0 to 48. Let go of the button. Turn the key back to the original position and remove. Turn the dial to the right, or clockwise, until you hear a click. The combination is now the next combination in the series. Check the combination. If the combination is not the correct combination, repeat the above steps until the desired combination is reached.
