If you've ever questioned, "How does a door lock work?" The latch, which moves partly in and out of the lock cylinder mechanism when the door is locked, is the component that provides the solution. If the door is unlocked, the latch is still within the lock cylinder. The latch can only be released and the door unlocked with a key. To set up the lock manually, you must be familiar with how door locks operate. Assembling locks is a simple operation once you become acquainted with the door locking systems. You need to be familiar with the components of a door lock before we can discuss how locks operate. Understanding door locking systems will be simpler if you are aware of the characteristics and purposes of each component. Because it houses the locking mechanism, the cylinder is often referred to as the lock body. The spring-loaded pins that hold the lock shut are located within the cylinder. Without the proper key inserted, the spring-loaded pins will prevent the cylinder from turning. 
The door cannot open because of the bolt or latch. When the doorknob is turned, the latch is removed from the door jam. If the door is locked, the knob cannot be twisted, hence the latch will not release. The striking plate is a metal plate that is mounted on the jamb of the door. It is placed across from the lock. When the door is closed, it is also where the latch fits. To help the bolt stay in the proper position, certain striking plates feature lips. The area of the lock where the key is entered is called the keyway. The rotor, on the other hand, is the component of the lock that rotates when the right key is entered. It is situated within the lock's cylinder. Every time the spring is compressed, the cotter pin lines up with the grooves in the key. When the door is unlocked, it also causes the rotor to rotate. Instead, until the proper key is entered, the spring stops the rotor from rotating. A metal rod known as a spindle joins the two doorknobs on each side of the door. When the doorknob is twisted, the spindle turns and retracts the latch, opening the door. The doorknob or handle gives the home's owner a place to hold on. The outside knob or handle is the doorknob or handle that is located on the outside of the door. The interior handle or knob is found within. The majority of doorknobs are constructed of brass. The latch of a door lock is outside the lock cylinder and within the strike plate when the door lock is locked. It guarantees that the door won't unlock until the appropriate key has been entered. 
Each key has a unique set of ridges that fit into a certain lock. Key locks operate by spinning the cylinder to lock the door. When the cylinder is spun, the spring is released, causing the latch to shut. The inner door lock mechanism is activated by the correct key, which is also used to open the door. The key will align the pins after it is put into the keyway. With the cylinder turned, the door will be unlocked. The pins wouldn't line up properly if the incorrect key were used to unlock the door. As a result, the top and lower pins would not be separated, making it impossible to spin the lock's cylinder.

When the latch is raised, the actuator links the door handle to the gap. The door handle and the unlock system separate when the latch is lowered, preventing the automobile door from opening.
