What Is The Difference between Mortice Locks And Normal Locks?

Introduction

Have you ever wondered what makes some locks more secure than others? The type of lock you choose plays a crucial role in protecting your home or business.

In this article, we’ll explore the key differences between mortise locks and normal locks. You’ll learn why mortise locks are the preferred choice for security, durability, and functionality.

What is a Mortise Lock?

Definition and Explanation

A mortise lock is a type of lock that is embedded into a door. Unlike normal locks, which are mounted on the surface, mortise locks require a specific cut-out in the door called a "mortise." This design makes mortise locks more secure and durable.

Key components of a mortise lock include:

Component	Description
Lock body	The main part that houses all the internal mechanisms.
Lock cylinder	The key mechanism that locks and unlocks the door.
Faceplate	The visible part on the door surface that covers the lock body.
Internal mechanism	The complex system that enables locking, unlocking, and safety features.

Mortise locks are considered higher security than normal locks because their installation involves embedding the lock inside the door, making it harder to tamper with or bypass.

How Mortise Locks Work

Mortise locks work by using a key to turn the lock cylinder, which moves the internal mechanism to engage the lock. Here's how it works step-by-step:

1. Insert the key into the lock cylinder.

2. Turn the key to engage the internal mechanism.

3. The internal mechanism moves to either secure the door or allow it to open.

Mortise locks are embedded within the door, requiring a specially cut-out area. This differs from normal locks, which are mounted directly on the door's surface. The installation process of mortise locks is more intricate, which adds to their security.

Types of Mortise Locks

There are different types of mortise locks depending on their functionality:

Type	Description
Standard mortise locks	Basic, mechanical locking mechanism.
Smart mortise locks	Integrates with electronic systems for keyless entry, often used in commercial spaces.
Electronic mortise locks	Operate through keypads, cards, or biometrics for added security.

Mortise locks are designed for high security, anti-tampering, and weatherproof durability. These locks are ideal for both residential and commercial properties. Whether it’s a narrow office door or a heavy-duty industrial door, mortise locks provide reliable protection in various settings.

What is a Normal Lock? (Standard Locks)

Definition and Explanation

Normal locks, also known as surface-mounted locks, are simpler locks that are installed directly on the door's surface. Common examples include ball locks and lever locks. These locks are typically easier to install compared to mortise locks and are often used in low-security applications.

Key components of normal locks:

Component	Description
Lock body	The main housing that holds the locking mechanism.
Keyhole	The opening where the key is inserted.
Latch	The mechanism that keeps the door in place, typically simpler than that in mortise locks.

In contrast to mortise locks, normal locks are usually made of lighter materials like zinc or iron alloys, which makes them less secure than mortise locks.

How Normal Locks Work

Normal locks are fairly straightforward in operation. Here’s how they work:

1. Insert the key into the lock's keyhole.

2. Turn the key to disengage the latch and allow the door to open.

3. The latch slides into place to secure the door.

Unlike mortise locks, which need specialized installation to create a cut-out in the door, normal locks are mounted directly on the surface, making them easier to install.

Types of Normal Locks

There are several types of normal locks, including:

Type	Description
Ball locks	Often used for interior doors, they consist of a ball mechanism to lock or unlock the door.
Lever locks	Common in residential settings, lever locks are easy to operate and mainly used for low-security purposes.
Cylindrical locks	These locks are commonly found on exterior doors and offer slightly more security than ball or lever locks but are still considered less secure than mortise locks.

These locks are most commonly found in home settings, used for interior doors, cabinets, and other low-security areas. They are often chosen for their affordability and ease of use, though they do not offer the same level of protection as mortise locks.

Key Differences Between Mortise Locks and Normal Locks

Installation Process

Mortise Locks	Normal Locks
Requires a specialized door cut-out (mortise) for lock body installation.	Easier to install with basic drilling.
More secure due to embedded installation.	Less secure, mounted on the surface.

Structure and Design

Mortise Locks	Normal Locks
Built from strong materials like 304 stainless steel, embedded inside the door.	Made from lighter materials like zinc or iron alloys, mounted on the door's surface.

Security and Durability

Mortise Locks	Normal Locks
Higher security, resistant to tampering and harsh conditions.	Lower security, more vulnerable to tampering and wear.
Designed for longer durability.	Prone to corrosion and wear.

Compliance with Standards

Mortise Locks	Normal Locks
Certified to high security standards (e.g., EN 12209).	Often lack certification, lower security rating.

Advantages of Mortise Locks Over Normal Locks

Superior Security

Mortise locks provide higher resistance to break-ins and technical attacks. Some mortise locks offer up to 260 minutes of defense against tampering. These locks meet strict safety standards, like the QB/T 2474 certification, which ensures reliability and resistance to drilling, sawing, and pulling.

Durability and Longevity

Mortise locks are built for heavy-duty use. Their robust construction makes them ideal for commercial and industrial settings, where security is a priority. Mortise locks are resistant to corrosion and can withstand harsh environments, providing long-lasting reliability.

Versatility and Applications

Mortise locks are perfect for offices, commercial buildings, and high-traffic areas, where both high security and frequent use are essential. They can also be installed in narrow doors or glass doors, which normal locks cannot cater to. Mortise locks can integrate with modern electronic systems like fingerprint scanners and IC cards.

Ease of Use

Many mortise locks include auto-locking mechanisms (e.g., pull-to-lock handles), providing quick and seamless locking. This feature is particularly useful in commercial settings where efficiency is key.

The Limitations of Normal Locks Compared to Mortise Locks

Security Shortcomings

Normal locks are more vulnerable to tampering. They can be easily bypassed using common techniques like bumping or picking. Mortise locks provide much higher security and resistance to tampering.

Installation and Maintenance Issues

Normal locks require more frequent maintenance. They often need lubrication and cleaning to maintain smooth operation. They are also noisier during use, while mortise locks are designed to be smooth and quiet.

Lack of Compatibility with Modern Technologies

Normal locks are not compatible with smart systems. They cannot integrate with features like keyless entry or biometric security, which is possible with mortise locks.

Reduced Durability

Normal locks are more prone to wear, especially in high-traffic areas. Their components deteriorate faster than the heavy-duty components in mortise locks, making them less reliable over time.

When Should You Use a Mortise Lock vs. a Normal Lock?

Ideal Scenarios for Mortise Locks

Mortise locks are ideal for high-security areas like offices, commercial buildings, and government facilities. They are perfect for doors that withstand constant use or exposure to harsh environments. Mortise locks are also essential when smart or electronic integration is needed, such as keyless entry or smart access systems.

Ideal Scenarios for Normal Locks

Normal locks are great for residential settings, such as internal doors, storage areas, and cabinets. They are cost-effective and suitable for low-security applications where advanced features are unnecessary.
