Combination locks can be tricky—especially when they're attached to lockers at your school. Practice beforehand so you know exactly how to open yours. REALISTIC UNLOCKING The lock behaves exactly like a real one. Spin the dial to enter your combination, then tap or swipe up on the shackle to open. If you want to start over, just keep spinning and enter the combination again. HELPFUL HINTS If you make a common mistake when opening the lock—like forgetting to spin one rotation to the left before your second number—you’ll be notified with a friendly hint. WALKTHROUGH MODE If you get stuck, don't worry. Enable Walkthrough Mode to get step-by-step instructions as you open the lock. CUSTOMIZE YOUR LOCK Choose from six different dial colors: red, yellow, green, blue, purple, or black. GENERATE A RANDOM COMBINATION, OR CHOOSE YOUR OWN If you want to test yourself, generate a combination randomly. Or, choose your own in one of two number ranges: 0-39 or 0-49.
