Opening a 3 digit combination lock is relatively simple. First, you need to locate the reset button on the back of the lock and press it until you hear an audible click. This will reset your lock's current code to its factory setting, which should be 000 or 0-0-0. Once that’s done, turn the dial clockwise until it stops and align all of the numbers in a line with each other. Now set your own three digit combination by turning each number one at a time until you have reached your desired combo. Finally, pull down firmly on the shackle release latch located at the top of the padlock to open it up. Always remember to test out your new combination before closing it up just to make sure everything has worked properly!
