A Quick Simple Guide How to Open Combination Locks Without the Code

Combination locks are used for a range of things, including school and gym lockers and home security. It might be really frustrating not to be able to access your possessions if you lose the combination. If you don’t want to cut the lock open, there are a few additional options. These steps will allow you to unlock a combination lock without a code, but only on your own lock. Locks that do not belong to you should not be opened.

Approach #1 – Trying to decipher the Code

1 – Make sure you’re familiar with the lock.

There are three primary parts to a lock. The U-shaped portion that ties it to an object called the shackle. The dial is the rotating section with the numbers. The rest of the lock is made up of the body. The locking mechanism is usually on the left side of the shackle if you hold the lock with the shackle on top and the dial facing you.

2 – Put some pressure on yourself.

You’ll need to carefully pull up on the shackle to find a lock combination. It will be impossible to turn the dial if there is too much pressure. If you use too little, the dial will spin freely. You should apply light pressure. This may take some time to master.

3 – Find the first number.

Pull the shackle up carefully and hold it in place. Turn the dial clockwise, paying close attention until the lock clicks.

• Start with a lot of pressure then gradually ease off as you spin it around until you only run against resistance in one spot.
• You’re tugging too hard if the dial catches every few digits. You’re not pushing hard enough if it never catches. It should only catch in one spot, resulting in a click.
• If the click occurs between two numbers on the dial, round up to the higher number.
• To that number, add 5 and write it down. The first number in the combo is this one.

4 – As a starting point, choose the first number in the combo.

Before resetting the lock, it’s a good idea to rotate the dial a few times.

5 – To find the second number, turn the dial counterclockwise.

Turn the dial slowly while maintaining slight pressure on the shackle. Before reaching the second number, you need to go all the way around the mechanism once more.

• As you turn the key, the lock will bump and catch.
• The lock will eventually reach a point where it will be extremely difficult to turn. The second number is where you’ll come to a halt. On the same sheet of paper, make a note of it.

6 – Experiment with different combinations.

Testing every potential combination is one method of determining the third number. Set the first two numbers as if you’re about to unlock the door. Then carefully move the dial clockwise to test every potential combination.

• There should only be forty potential combinations at this time.
• For each combination, the first two numbers do not need to be reset. Toggle one number, then turn another. Rep the procedure until the lock unlocks.

7 – In order to find the third number, you must do a test.

Testing the catch is a different way to find the third number. To reset the lock, turn the dial clockwise a few times and set it to 0. Turn the dial clockwise while applying upward pressure to the shackle.

• The lock will catch a few times, allowing for minor back and forth movement between two numbers.
• In the centre, write the number. If the lock catches between 33 and 35, for example, write 34 on a separate piece of paper. This isn’t always the final figure.
• The lock will also catch in the middle of a number. For instance, the range could be 27.5 to 29.5. Do not put down the middle number if it is not a whole number, such as 28.5. Whole numbers are always used in lock combinations.
• Follow the dial all the way around, noting all the entire numbers where it catches. You should write down four or five numbers.
• The majority of the numbers will follow a pattern, such as all ending in 5. The final number in your combination is the only one that does not suit the pattern.

Approach #2 – Making a Shim

1 – Examine Your Lock.

Manufacturers of recently designed locks have intended them to be shim-proof, yet it is still feasible to pick them in some situations. On older locks, this strategy will work better.

2 – Identify the location of the locking mechanism.

To successfully apply a shim, you must deal with the location where the shackle latches, as working with the hinge will yield no results.

• When looking at the lock with the shackle on top and the dial facing you, the locking mechanism is usually on the left side.

3 – Make a cut in an aluminium can.

You may make your own shim by chopping up a Coke can. Cut off the top, then the length, and finally the bottom of the can with scissors.

• You should be left with a single piece of aluminium that used to be the can’s body but is now a long strip of metal.

4 – Cut a piece of metal into a strip.

Turn the metal horizontally so that you’re cutting the material’s shorter side. The shim will be made from this piece.

• Cut a strip slightly wider than one inch.
• If any of the margins are ragged, they should be trimmed.

5 – Make two curving incisions in the skin.

Cut two curves from the bottom of the little strip of metal, resembling the letter U, by holding it horizontally.

• In the middle of your strip, centre the U.
• Make sure you don’t go all the way to the top.

6 – Make two diagonal slits in the skin.

Remove the triangles of material by cutting diagonally upwards from the bottom of the metal roughly a quarter of an inch from the base of the U and intersecting with the top of the U.

• The end product should be a metal strip that resembles the letter M, but with the middle of the M bent rather than pointed. This is going to be the shim.

7 – To form a handle, fold the sides together.

Lower the top of the metal by about an eighth of an inch. Then fold the sides of the metal sheet upward around the top.

• By folding the sides, you may have a shim handle that won’t cut your hand with a sharp edge.

8 – Fold the shim around the lock’s shackle gently.

The shim’s U should be facing down.

• Wrap the shim around the exterior of the shaft gently first, so it moulds to the contour of the shaft.
• When you’ve achieved the desired form, rotate the shim so that the U is on the inside of the shackle and your handle is on the outside.
• Make sure you do it on the side of the shackle with the locking mechanism.

9 – Hold the shackle in place with your finger by pressing it up as far as it will go.

Slowly slide the shim into the crack between the shackle and the lock itself with your other hand.

• It will take a few minutes, and there is no need to rush or force it.
• Stop when you’ve worked it in as far as it’ll go.

10 – Remove the lock.

With one hand, pinch the shim. Press the shackle down with one hand, then draw it up with the other. The lock ought to open.

Approach #3 – Using the Serial Number

1 – Find the serial number.

Make a note of the number stamped on your lock. A serial number may or may not be present on some locks.

2 – Bring the lock to a brand’s distributor or retailer.

Request that the distributor contacts the lock’s manufacturer on your behalf to verify your ownership and supply the combination.

• Retailers are unlikely to help you if the lock is attached to an object, such as a box.
• It’s possible that the retailer will charge you for this service.

3 – Directly contact the makers with a missing combination form.

Check the manufacturer’s website to see if this service is available.

• Manufacturers are unlikely to release the combination over the phone or over email because of security concerns.
• You may be asked to provide proof of ownership, such as a notarized document attesting to your ownership.

4 – Consult the owner.

If the lock belongs to a school or company, the administrators may have a list of possible combinations based on serial numbers. Make a note of the serial number so you may bring it to the main office.

• If the lock is tied to something, such as a locker, you’ll need to show confirmation that you have permission to access the contents of the locker.

Warnings

• It is illegal to destroy or steal other people’s property. Even if it’s just a prank, don’t use any of these methods to tamper with a lock that isn’t yours.
• Some of these techniques may not be applicable to all locks.
