The earliest key-operated lock was a huge wooden bolt attached to the exterior of a gate. Pins were placed into the holes for preventing it from being moved. A key elevated the pins, allowing the bolt to be moved and the gate to be opened. Later the locks were created using three fundamental principles: the warded concept, the lever concept, as well as the pin-tumbler concept. The warded idea was created by the ancient Romans. To open the bolt, the key would just have to pass through a series of wards.
The mechanism of a lever lock includes one or otherwise more levers. Before the bolt may be removed, the lever should be lifted to a specified height. Only the proper key may elevate the levers to the exact height required. The current pin-tumbler lock is based on the same idea as the ancient Egyptian lock.

The most common type of key card is one with a magnetic stripe. Electronic Padlock has been used widely.
Electronic combo locks, often called as keypads, employ an electromagnet installed in the door as well as a bolt placed in the wall. Whenever the door has been 'locked,' the electromagnet however is engaged and adheres to the bolt, therefore locking the door. To unlock these particular locks, a number combination is required.
