Description

A door lock is a mechanical or electronic device used to secure a door and restrict access. It typically consists of several key components:

1. Cylinder: The part where the key is inserted. In a pin tumbler lock, it contains pins that align when the correct key is used.

2. Bolt: A metal piece that extends into the door frame to secure the door when locked. This can be a deadbolt, which is more secure, or a latch bolt, which can be spring-loaded.

3. Faceplate: The visible part of the lock on the door’s edge, providing protection and aesthetic appeal.

4. Keyway: The slot in the cylinder where the key is inserted, designed to fit a specific key shape.

5. Housing: The body of the lock that holds the cylinder and bolt mechanism.

6. Lever or Knob: The part you turn or press to open the door when it’s unlocked.

Locks can vary widely in design and technology, ranging from traditional mechanical locks to advanced smart locks that use keypads, biometrics, or smartphone connectivity for access. Security features may include anti-pick pins, reinforced materials, and more.
