Unlocking Three Digit Lock: Easy Step-by-Step Guide


Three-digit locks are commonly used to secure luggage, briefcases, and gym lockers. While these locks are convenient to use and provide a basic level of security, they can also be frustrating to unlock if you’ve forgotten your combination. Fortunately, unlocking a three-digit lock is not as complicated as it may seem.

Step 1: Determine the Lock’s Combination

Before you can unlock your three-digit lock, you need to determine the lock’s combination. If you don’t already know the combination, try the following methods:

  • Method 1: Use a Default Combination
  • Some three-digit locks come with a default combination. Check the lock’s packaging, manual, or the lock itself to see if there is a default combination. Common default combinations include 000, 123, and 999.

  • Method 2: Try Common Combinations

  • If you’re unable to find a default combination, try common combinations. Some of the most common combinations are 123, 321, 000, 111, 999, and 888. Start with these combinations and work your way up/down from there.

  • Method 3: Use a Combination Calculator

  • If the first two methods don’t work, use a combination calculator. There are many combination calculators available online that will help you determine the correct combination based on the lock’s model number or brand.

Step 2: Turn the Dial

Once you have the combination, turn the dial to the right (clockwise) at least four times, until the first number of the combination lines up with the “index” mark on the lock. The index mark is usually located at the 12 o’clock position on the lock.

Step 3: Turn the Dial to the Left

After the first number is lined up with the index mark, turn the dial to the left (counterclockwise) until the second number of the combination lines up with the index mark.

Step 4: Turn the Dial to the Right Again

Once the second number is lined up with the index mark, turn the dial to the right (clockwise) until the third and final number of the combination lines up with the index mark.

Step 5: Pull the Shackle

With the correct combination set, pull the shackle (the U-shaped part of the lock) and the lock should open.


Unlocking a three-digit lock is a simple process once you know the correct combination. By following the steps outlined in this guide, you should be able to unlock your three-digit lock in no time. Remember to keep your combination in a safe place or choose one that is easy to remember to avoid the frustration of having to unlock your lock again.


How do I unlock a three digit lock?

To unlock a three digit lock, first make sure you have the correct combination. Then, turn the dial to the right (clockwise) a few times to clear any previous attempts. Next, turn the dial to the first number in your combination. Turn the dial to the left (counterclockwise) until you reach the second number. Finally, turn the dial to the right again until the third number is aligned with the arrow or indicator. The lock should now open.

What if I forgot the combination to my three digit lock?

If you forgot the combination to your three digit lock, there are a few things you can try. First, try all possible combinations starting with 000 and working your way up to 999. This can be a time-consuming process, but it’s worth a try if you don’t have any other options. If that doesn’t work, you can try contacting the manufacturer to see if they have any suggestions for unlocking the lock or resetting the combination.

Can I change the combination on my three digit lock?

Most three digit locks can have their combination changed. To do this, follow the manufacturer’s instructions for changing the combination. Typically, this involves opening the lock with the current combination, inserting a tool (such as a paperclip or pen) into a small hole on the side of the lock, and then setting a new combination. Be sure to choose a combination that you will remember but that is also secure.
