This is how the cylinder recognizes the correct key and allows it to turn. Each brand of lock has a distinct keyway that permits it to be locked or unlocked using the use of a particular type of key. Within a single brand, there are different keyway styles and sizes to choose from. This allows for a level of security to different locks, as keys of the same brand are not able to unlock the other's. In most homes the latch is operated with a lever, which can be pulled down or lifted to let the bolt go. This is often more ergonomic than a knob which requires you to turn it. However, some commercial settings still utilize knobs to provide additional security. When the correct key is inserted, the spring-loaded pins move into position allowing the plug to be rotated. The pins are aligned with grooves on the blade of the key, allowing the lock to recognize the right key. If the key or cylinder is not properly inserted the pins will be moved to the control shear, rather than the operating line. The lock won't open.
