Combination lock - Wikipedia, the free encyclopedia. A combination lock is a type of locking device in which a sequence of numbers or symbols is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed numerals which directly interact with the locking mechanism, or through an electronic or mechanical keypad. Types range from inexpensive three- digit luggage locks to high- security safes. Unlike a regular padlock, combination locks do not use keys. Exploded view of the rotating discs. The notches on the disc correspond to the numerals in the correct combination.
In this case, the combination is 9- 2- 4. The discs are mounted on one side of the lock, which may in turn be attached to the end of a chain or cable. The other side of the lock, or the other end of the cable, has a pin with several protruding teeth.

When the notches in the discs align with the teeth on the pin, the lock can be opened. This lock is considered to be one of the least secure types of combination lock; many locks of this type can be quickly opened without knowledge of the correct combination. Opening one in this fashion depends on slight irregularities in the machining of the parts. Unless the lock is machined precisely, when the pin is pulled outward, one of the teeth will pull more strongly than the others on its corresponding disc. This disc is then rotated until a slight click is heard, indicating that the tooth has settled into the notch. The procedure is repeated for the remaining discs, resulting in an open lock, and a correct combination, in very little time. Customarily, a lock of this type 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.
The cams typically have an indentation or notch, and 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.

When these two strategies are combined on a lock with the properties given above, the brute force search time is reduced by greater than 9. This is still significantly better security than multiple- dial locks and many keyed locks, but unacceptable for high security applications.
Inexpensive padlocks are often also susceptible to direct mechanical attacks, such as the use of a padlock shim which can release the shackle without entering a combination. Early combination padlocks made by Master Lock could be cracked by pulling on the shackle of the lock and turning the dial until it stopped; each numeral in the combination could be revealed in this manner.
