how to use a combination lock

Download Article

A combination lock is useful for your school locker, gym locker, bike, or anything else that you'd like to keep safely stowed. Once you know your combination, opening a combination lock is very easy—just a couple turns to the left and right, and presto—the lock is open! If you want to know how to open a combination lock, just follow these steps.

1

Buy a combination lock. Combination locks can be found at most hardware, home improvement, and sports stores across the US. Some stores that sell combination locks are The Home Depot, Lowes, Sears, Modell's, Staples, and Walmart.
2
Find the combination on the sticker on the back of the lock. Most of the time, your new combination lock will come with a sticker on the back of the lock, telling you your lock's combination. Remove the sticker carefully. Write down the combination and throw out the sticker -- you don't want to leave the sticker around in case someone else finds it and knows it's the combination to a lock.^[1]
- Start memorizing your new locker combination. This will make it easier for you to consistently open the lock.

1

Turn the dial on the lock clockwise three times. Turn the dial to the right. This clears the lock and resets it so that it's ready to open.^[2]
2

Stop turning when the marker points to the first number of the combination. The marker or line should be at the top of the dial, pointing to the twelve o'clock position. In many cases, it will be red. The first number on this lock's combination is 36, so you should stop turning the dial when the marker points to that number.^[3]
3

Turn the dial back to the left for one full turn. Spin it counterclockwise one full turn, past the first number (36), then stop at the second number—in this case, 10.^[4]
4

Turn the dial to the right. Finally, turn the dial clockwise again and stop at the last number on the sticker—1.^[5]
5
Open the lock. Pull up the shackle at the top of the lock, and it should open right up. You can also hold on to the shackle and pull down the lock.
- If it doesn't open, repeat the process from the beginning. Once you've partially engaged the tumblers, you should clear out the lock before trying again.

1

Insert the shackle. Spin the shackle around so that the opened portion is above the hole, and push it into the opening at the top of the lock.
2

Spin the dial. Turn the dial in any direction for three turns. It doesn't matter what number you stop on. This process will disengage the tumblers and will make it so that you'll have to start all over again with the first number if you want to open it.
3

Test it. Make sure it's locked by pulling on the lock or shackle. If it opens, lock it again.

Do it every time.

If you're at school, try it once or twice more. If it still doesn't open, ask a nearby teacher for help.

Tell someone in your school's administration office; they'll either give you the combination on record or change it for you.

No you cannot. The lock will already have a code on it and you cannot change it if your school gave it to you or if you brought it in a store.
Question

What do I do if the first and second numbers are the same on my combination lock?

Do the same thing you would do if they were different numbers. Say the combination was 15-15-09. You would turn it clockwise until you get to the number 15 and then stop, turn it counterclockwise past the number 15 and keep turning until you get to it again, then turn clockwise to the number 9. Then pull on the lock and it should open.

Placing tension on the shackle (the U-shaped part that holds the thing you want to lock) will place more friction on the mechanics of the lock. Just leave the shackle alone and you'll open the lock smoothly.
You don't have to touch the number exactly, you can be about two numbers off before it won't click in the lock's inner workings.
The more you do it, the easier it'll get!
If you mess up, keep trying. It'll come to you sooner or later.
If your lock is not opening even if you tried more than one time just check if its not hard when your turning it if it is hard than you need a new lock.

Article SummaryX

If you need to open a combination lock, start by turning the dial on the lock clockwise (to the right) 3 times. Stop turning when the marker or line points to the first number of the combination. The marker or line is often red and will be at the top of the dial. Then, turn the dial counterclockwise (to the left) for 1 full turn, passing the first number of the combination, and stopping at the second number of the combination. Finally, turn the dial clockwise (to the right) and stop at the last number of the combination. Pull up the shackle at the top of the lock and the locker should open right up. If the locker doesn't open for you, repeat the process from the beginning and go a little slower this time to make sure you input the correct combination numbers. If the locker still won't open, the combination you have for the locker may be incorrect. For more tips, including how to properly close the lock, scroll down!
