How to Crack a Combination Lock?

Combination locks have a flaw that allows anyone to figure out the combination in a few attempts. The procedure takes less than two minutes and involves very little expertise. If you don’t know the code to a combination lock, you can destroy the lock, hire a professional locksmith in Chicago, or use a shim. You start by resetting the code on a three-digit lock. To open it, you must put pressure on the lock from the shackle. Examine each dial to find which one has the most resistance. Then, with the most resistive dial turned, listen for clicking sounds. This article will show you how to crack a combination lock in a couple of minutes! It will help you to open the combination locks that you may have lost the combination to.

How does a Combination Lock Work?

A combination lock includes dials, each with a keyhole in the middle. The keyway of all the dials on the lock match when you add the right combination. It allows the pin to enter. The keyholes will misalign when you shift the dials. You will not be able to remove the pin as it will lock in place.

Most combination locks contain three numbers. There are three cams within the lock, each corresponding to a different digit in the code. A cam is just a little wheel. All three of these cams have a hole in the center. They connect to a short shaft that protrudes from the lock case. Only one of these cams connects to the shaft. It implies that when you rotate the front dial, the last cam will rotate because it is attached to the shaft. The remaining two cams will not rotate, staying in place while the shaft turns quickly.

Steps to Crack a Combination Lock

On the outer border of every cam is a small notch. When you lift on the lock’s shackle, a lever inside the lock tries to move but the three cams will block it. The lock will unlock when you lift on it when all three notches on the cams are correctly aligned under the lever.

When cracking a combination lock, a piece of wire can be used as a temporary handle to help you hold the lock. You’ll need to apply a consistently strong upwards pressure on the shackle throughout the whole process to fracture the lock. You’ll need a good grip, which might be tough to achieve with just your hands. The ability to deliver robust and consistent pressure to the shackle is critical to increasing the friction on the lock’s dial. It will result in a clicking sound and an upward motion when a dial moves to the correct values.

You can continue to the next dial after you feel the shackle shift higher and produce a clicking sound. Continue the process until all of the dials on the lock have been done, and the lock will crack. If the lock is attached to a sturdy item, such as a barrier or a door, a wire is not required because the lock is attached to anything that offers you more grip and traction, allowing you to finish the process.

Applying Pressure on the Lock

Pass your wire through the hole on the lock and bend it halfway across the shackle. This will serve as your temporary grip, giving you a firmer and more secure grasp on the lock to make the process go more smoothly. Then, holding the wire firmly in your hands, press down strongly on the head of the lock, be sure to maintain the same level of pressure on the lock throughout the process. You must now turn each of the dials a little in each direction while maintaining constant pressure on the lock. You’ll immediately figure out which dial is the most difficult to turn, and that’ll be the one you start with.

Finding the First Digit

Begin to slowly turn the dial till you hear a click sound and feel the shackle change position upwards. Examine the dial and write down the digit, then slowly turn that same dial to verify.  If it keeps making a clicking sound on the same number with each turn, you have decoded the first number of the combination and can proceed to the second dial.

Finding the Remainder Digits

Turn each of the remainder dials to see which one is the most difficult to turn. Continue the procedure for the second dial until you’ve worked out the second digit of your code. If you have a three-digit combination lock, you should only need to find out one more dial. All you have to do now is maintain consistent pressure on the lock while slowly rotating the final dial. The last number needed for the combination will line up with the other two you previously found out as you revolve the dial, and the shackle will release.
