Combination locks are the most common type of lock around for smaller objects. It usually consists of a sequence of symbols and numbers. These locks have been around since the thirteenth century. The lock has a pin and each number from the combination releases a piece of the puzzle so to speak. Combination locks are a little more complicated when it comes to cracking the code. Even if an intruder figures out the combination it does not end there. They will still have to find out the variation of how the numbers are used. Combination locks are significantly better than most multi-dial and keyed locks, however it is not recommended for high security purposes.
The most common type of lock is the original combination lock. Combination locks are very simple to use, usually including a number or symbol sequence to unlock the code. The first lock of sorts was created in the 13th century by an Arab inventor and engineer. There are two common types of combination locks in circulation of every day use, multiple-dial locks and single-dial locks.
Multiple-dial locks are one of the simplest types of combination locks, often seen on low-security bicycle locks and briefcases. It is described as using several rotating discs with notches cut into them. The lock is secured by a pin with several teeth on it which hook into the rotating discs. When the notches in the discs align with the teeth on the pin, the lock can be opened. The simplicity of this lock has considered it to be the least secure of all lock variations because most locks do not require the exact combination to open.
Single-dial locks are combination locks normally found on padlocks or safes which may use a single dial which interacts with several parallel discs. Single-dial locks are also common on school and gymnasium lockers. In most cases, this type of lock is opened by rotating the dial clockwise to the first numeral, counterclockwise to the second, and so on in an alternating fashion until the last numeral is reached; when the correct combination is entered, the notches align, allowing the latch to fit into them and open the lock. Depending on the quality of the lock, some single-dial combination locks can also be defeated relatively easily. Yet, this is still significantly better security than multiple-dial locks and many keyed locks, but unacceptable for high security applications.
Despite the simple nature in the name of a combination lock, figuring out the combination is only the first step in breaking the code because both types require the correct variation in the entry of the numbers or symbols.
