8) Stator
The stator is that component of the cylinder that connects with the rotor and allows the rotor to turn when the keys go in.
9) Trim
Commonly known as rose, available in different knobs, levers, or handsets. These are the main feature of the cylinder lock. They are interlinked with keyway.
10) Faceplate
This is the metal piece through which the bolts are tightened and help the strike plate to get in its desired place.

As we all know that the lock has pins in it. That is connected to the cylinder. If we use the wrong key to unlock the mechanism, there will be no space left between the upper and the lower pin that does not allow the rotation of the cylinder. Hence, as a result, the lock will not get open.
When we insert the right key. It sits right in the keyhole that triggers the pins that led to a rotation to the cylinder. Now that rotation of cylinder unleashes the lashes spring. Hence, as a result, you can easily unlock your lock. with the help of the right key. So basically the door will open if you put the right key in the keyhole and if not then it will not.
