Everything about Combination lock

Lock using symbols rather than a key

A combination lock is a type of locking device in which a sequence of symbols, usually numerical digits, 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 symbols 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 ordinary padlocks, combination locks do not use keys. Wikipedia →
