Science Behind Mortise Lock Security

Mortise locks are a type of lock with a unique mechanism that makes them more secure than deadbolt locks. To improve your home’s security, mortise locks should be a top consideration. The mechanism of mortise locks differs from the mechanisms of deadbolts and door knob locks. This blog will cover the science behind mortise lock security so that you can appreciate the depth of the technology. It will also help you decide if mortise locks are right for your home or business.


Mechanisms of a Mortise Lock

Mortise locks use a cylinder as the locking mechanism. The cylinder is cylindrical and fits into a mortise in the door handle. The key must turn in the lock to open the door, and the cylinder cannot be removed without breaking the lock. To change cylinders, the lock must be opened, the old cylinder removed, and a new cylinder fitted. This type of lock is more secure than a deadbolt because it cannot be picked easily with a standard key. A mortise lock requires two hands to open it, making it less accessible to unauthorized persons. On top of that, it is also easier to secure Mortise locks than deadbolts because they are easier to secure and unlock. However, people with expertise with Mortise locks should be able to handle them properly so that no one accidentally opens their door with a standard key or picks their lock with tools. Now, see the Mortise lock security features.


Security Features of Mortise Locks

Mortise locks use a key that must be inserted into the lock’s mortise to open the door. This key is usually the same shape and size as the mortise, so it’s easy to access. The lock mechanism is activated when the key is turned 90 degrees to the left or right, which opens the door. The key must be turned another 90 degrees to open the door and inserted into the lock’s handle. The deadbolt feature of mortise locks can also be activated from the outside to secure the door from the inside. This prevents intruders from opening the door without proper authorization. A lock cylinder contains four keys and must be replaced when it wears out. Plus, all mortise locks are designed to withstand high-security environments, such as those found in banks and government buildings.

Evaluation of Mortise Lock Security

Mortise locks are a common locking mechanism used in buildings and homes to secure doors and windows. They use a tumbler lock system that can be easily compromised, making them a poor choice for security purposes. Three common types of mortise lock security are keyless entry, thumb turn entry, and keyed entry. The keyless entry opens the lock without using a key or code. This makes it easy to open the door or window without accessing a safe or secure location with a physical key or fob. The second type of mortise lock security, thumb turn entry, requires the user to turn the tumbler past a certain point to open the door or window. This type of lock provides additional security over keyless entry because a physical key is required to bypass its protections. When selecting mortise locks for security purposes, it is important to consider the type of locking mechanism, access control features, attack scenarios, and countermeasures. To improve mortise lock security, installing quality locks and using strong passwords on doors and windows is vital.



To summarize, mortise locks are small lock cylinders that can be used to secure doors and cabinets. They are easy to install, secure, and flexible. They are ideal for securing cabinet drawers, filing cabinets, and safes. Their use has become increasingly popular over the years as security measures have been simplified.
