Types of combination locks and how to crack them

The combination lock is a common security locking device, which controls the opening and closing of the lock through the input of a code. This article will introduce the types of combination locks and cracking methods to help readers better understand the working principle of combination locks.

Multi-Dial Combination Locks

Multi-Dial Combination Locks are the simplest type of combination lock, commonly found on bike locks with low security settings, and use multiple dialing loops. Each ring has a recess in the center. A shaft in the center of the lock has several protruding teeth to catch the toggles. When the dial ring is turned to the correct combination of codes, the lock can be opened.

Single Dial Combination Locks

Single Dial Combination Locks are used on padlocks or magazines and can have only one dial. The dial pushes several counterbalancing disks or cams behind it. It is customary to open this type of lock by turning the dial clockwise to the first digit, then counterclockwise to the second digit, and so on to the last digit. The cams usually have dimples on them, so that when the correct combination is turned in, they all line up and the lock can be opened.

How to break a combination lock

There are many ways to break a combination lock, the easiest of which is to use a pulling hook or pliers to pull the lock out and then use a key or other tool to open the lock. In addition, you can pull the lock outward by the shaft, and one of the teeth will tighten the toggle more than the others. Then you can rotate the tightened toggle until you hear a small "snap" sound, which indicates that the tooth has entered the correct recess. Repeat this procedure and the lock will be open in no time.
