	Contained inside the mechanism are discs, usually three, with notches that must be aligned to allow for a release of the piece holding the lock in place, and the lock to open. The position of the discs are manipulated by turning the dial left and right; on the dial is a catch - a sort of nub - and on each side of the discs is also a small catch. As the dial rotates, there will not be enough space for the catch on the dial to pass the catch on that side of the disc, and so the disc will begin to rotate with the dial. As this disc rotates, its catch will in turn begin rotating the next disc in a similar fashion. Once all discs and the dial are rotating together, the dial is rotated until the last disc is in place and the notch is in the proper positioning, then by rotating the dial in the other direction, the catches will all disconnect, starting from the dial to the first disc and so on until they connect from the other side and the discs begin to rotate together by the same method but in the opposite direction. In this way, the remaining discs are able to rotate and change their position without further disturbing the last disc. The process is completed back and forth until all discs are in place, and the lock is released.

			In movies, rotary combination locks on bank vaults are commonly opened by thieves using a stethoscope. The principle is that each dial catch will make a small sound when it rotates into position. In reality, safemakers install false click generating mechanisms and sound deadening devices on the catches to make aural detection extremely difficult.

	The earliest combination lock was excavated from a Roman tomb in Athens, Greece. Attached to a small box, it featured several dials instead of keyholes. In 1206, the Muslim engineer Al-Jazari documented a combination lock in his book al-Ilm Wal-Amal al-Nafi Fi Sina'at al-Hiyal (The Book of Knowledge of Ingenious Mechanical Devices). Muhammad al-Astrulabi (ca 1200) also made combination locks, two of which are kept in Copenhagen and Boston Museums. Gerolamo Cardano later described a combination lock in the 16th century.

	A '''combination lock''' (or '''permutation lock''', '''word lock''') is a keyless [[~~Lock\|~~lock]] that uses a sequence of letters, numbers, or symbols to open the lock. Unlike keyed locks, combination locks require that a user ~~know~~ the proper sequence of characters to open the lock, much like knowing a password for a computer login. A combination lock works by correctly positioning internal components as the sequence is entered, usually through the use of one or more dials.

	Combination locks are most commonly associated with [[Safe\|safes]], but are also popular in low security applications in the form of padlocks. Because they do not have keyholes through which to manipulate internal components, most combination locks are compromised through [[Decoding\|decoding]] or [[Bypass\|bypass]] rather than picking.

			Combination locks are most commonly associated with [[safe]]s, but are also popular in low security applications, particularly [[padlock]]s. Combination locks are typically compromised via [[decoding]] or [[bypass]] rather than picking because they offer no direct access to locking components.
