Before attempting to unlock the lock, it is important first to understand its basic mechanism. Most three-digit combination locks feature dials with numbers ranging from 0-9 on each dial. To open the lock successfully, you must align all three dials so that each number matches up with its corresponding notch.

Step Three: Test Combinations

Try different combinations based on your identified number sequence until you find one that works. Begin testing combinations where two of the numbers match up with their corresponding notches and move through every possible third digit until success is achieved.

  • Try easy-to-guess codes such as 123 or 000 before moving on to other possibilities.
