What Are Deadbolt Locks?

Robust deadbolt locks are single-cylinder locks that offer a high level of security and people commonly use them in residential and commercial settings.

Deadbolt locks consist of several key components:
  1. Bolt: The bolt is a thick, solid metal bar that extends into the door frame’s strike plate when the lock is engaged. This part of the lock is the primary mechanism responsible for securing the door.
  1. Cylinder: The cylinder is the part of the lock where the key is inserted. It contains the tumbler pins, which align with the key’s unique grooves to allow the lock to turn and engage or disengage the bolt.
  1. Keyway: The keyway refers to the opening in the lock cylinder where you insert the key. It is designed to match the specific shape of the key for proper operation.
Deadbolt locks offer enhanced security for several reasons:

Resistance to Force: Deadbolts are less susceptible to forced entry techniques like lock bumping or picking due to their solid construction and lack of springs.

Single-Cylinder and Double-Cylinder: Deadbolts come in two types: single-cylinder and double-cylinder.
