A typical door lock comprises several key components:

  • Cylinder: The core of the lock where the key is inserted.
  • Key Pins: These pins align with the cuts on your key to allow it to turn smoothly.

The most common type of door lock is the pin tumbler lock. Here’s how it works:

  • Alignment: Once the pins align at the shear line (the boundary between the cylinder plug and the outer housing), the cylinder plug can rotate freely.
  • Rotation: With the pins in place, the cylinder plug can now rotate, retracting the latch or bolt and allowing you to open the door.

Modern door locks often include additional features for enhanced security and convenience:

  • Deadbolts: The strongest layer of protection to extend a solid metal bolt into the door frame.
