Install the cylinder in your door after determining its length. Start by using a drill to create an opening for the face of the door. This is where the handle or knob will be placed and should be slightly larger than the diameter of the cylinder you've created. Afterward, attach the interior handle or knob to the new handle and make sure it goes through the spindle of the latch and is able to turn smoothly when it is turned.

The keyway on a lock is the shape of the cylinder's interface and the key. The key is made up of a series of ridges and grooves which are affixed to its "blade" and, when it is inserted, they coincide with the cutouts in the pins of the cylinder. The cylinder is able to rotate if it recognizes that the key is the correct one.
Each brand of lock has a distinct keyway, which allows it to be locked or unlocked by using a specific key. There are various keyways sizes and shapes within the same brand. This allows for a level of security between different locks, as keys of the same brand are not able to unlock the other's.
In most homes the latch is operated by an adjustable lever that can be pushed downwards or lifted to open the bolt. This is more comfortable than the knob that needs to turn. However some commercial settings utilize knobs to provide additional security.
When the correct key is put in, a set of spring-loaded of pins move into place so that the plug can turn. The pins also align with grooves in the blade of the key, which allows them to recognize the correct key and denying access. If the cylinder is manipulated improperly, or if the key is not a proper fit, the pins will shift to the control shear line rather than the operating shear line, and the lock will not be able to open.

Then, place the knob that was previously used with the new barrel and push rod back into position. Before reassembling, it's important to check that all parts are positioned correctly (the rod and the barrel as well as the spring/lever housing).
