The key's “blade” is made up of a series of grooves and ridges that run along its length. When inserted into the lock, they align with the pins of the cylinder. This is how the cylinder detects the correct key and allows it to rotate. Each lock brand comes with a unique keyway that allows it be locked or unlocked with a specific type of key. Within a single brand, there are different keyway shapes and sizes available. This gives a certain level of security between different locks since keys of the same brand are not able to unlock each other's. In most residential settings, the latch is operated using a lever, which can be pushed down or lifted to release the bolt. This is more ergonomic than the knob that needs to turn. Certain commercial settings still employ knobs to provide security. When the key is correctly installed, a spring-loaded set of pins shifts into position so that the plug can move. The pins align with grooves on the blade of the key which allows the lock to recognize the correct key. If the cylinder or key is not properly inserted the pins will shift to the control shear rather than the operating line. The lock will not open.
