How Does a Mortise Lock Work?

Mortise locks are a popular choice for securing homes and businesses due to their reliability and durability. This article explains how mortise locks function and why they might be the right choice for your security needs.

Mortise Locks

A mortise lock involves a lockset that fits into a pocket cut into the edge of a door. Known for their strength, these locks are commonly used in commercial settings and older residential properties.

Components of a Mortise Lock

Mortise locks consist of several key components:

  • Lock Body: The central part housed inside the door.
  • Strike Plate: Attached to the door frame, it aligns with the lock bolt.
  • Lock Cylinder: Where the key is inserted.
  • Handle or Knob: Used to operate the lock.

How Mortise Locks Work

  • Inserting the Key: When you insert the key into the cylinder, it aligns the lock’s internal pins.
  • Turning the Key: As the key turns, it rotates the cylinder, engaging or retracting the lock bolt.
  • Opening the Door: With the bolt retracted, the door can be opened by turning the handle.

The Installation Process

Installing a mortise lock requires precision:

  • Cutting the Mortise: A pocket is created in the door to fit the lock body.
  • Fitting Components: The lock body, cylinder, and strike plate are precisely installed.
  • Testing the Lock: Ensuring smooth operation and alignment.

Benefits of Mortise Locks

  • Enhanced Security: Thick bolts and complex structures provide high security.
