There are a number of holes on the surface of a lock plug, and their size should fit that of the holes on a lock body and ensure necessary concentricity. Generally, the lock plug is not allowed to rotate randomly when the upper pins in the lock body go into the lock plug or the lower pins in the lock plug go into the lock body. As the key goes into the lock, the blade fits those pin holes and the length of the groove on that blade corresponds to that of the upper pins, thus the contact surface between the upper pins and the lower pins coincides with that of the lock plug and the lock body. In this way, the lock plug can freely rotate to lock or unlock a door.



In the middle of the lock plug is the keyway, with one end letting the blade slides into and the other end being a lever. The protruding part above the groove is used to prevent the lower pins from falling and to ensure security. In addition, there are 5 small holes being arranged in a straight line above the lock plug for placing pins of different lengths, which are spherical so that the key can easily slide into the keyway.
