Cylindrical vs Mortise Locks: Which One Is Right for Your Security Needs

Cylindrical vs Mortise Locks: Which Is Right for Your Security Needs?


When it comes to securing your property, choosing the right lock is essential. Two of the most commonly used lock types are cylindrical locks and mortise locks. While both offer protection, they differ significantly in design, installation, and security features. Understanding these differences helps you make an informed decision to enhance your building’s safety.

What Are Cylindrical Locks?


Cylindrical locks are widely used in residential and light commercial settings. They are installed through the door with two holes: one through the face for the lock chassis and another on the edge for the latch.

  • Ease of Installation: Quick and straightforward, making them a favorite for DIY projects.

  • Cost-Effective: Generally more affordable both in terms of unit price and labor costs.

  • Standard Security: Sufficient for internal doors and low-to-medium security needs.


However, cylindrical locks may not be ideal for exterior doors where higher security is important. They tend to have fewer internal components, which can make them easier to pick or force open compared to mortise locks.

What Are Mortise Locks?


Mortise locks are considered more robust and are commonly used in commercial or high-security settings. Installation involves a pocket (or mortise) cut into the edge of the door to fit the complex locking mechanism.

  • Durability and Strength: Built with heavy-duty materials and more intricate internal systems.

  • Enhanced Security: Mortise locks are more resistant to tampering, picking, and forced entry.

  • Versatility: They often support additional features like deadbolts, latch bolts, and privacy functions in one integrated system.


While they require professional installation and come at a higher cost, their security benefits often justify the investment, especially for areas requiring maximum protection.

Making Your Decision


If you're securing a residential interior door or a low-risk entrance, cylindrical locks are a suitable choice due to ease of use and affordability. However, for main entry doors, commercial properties, or areas with a high risk of intrusion, mortise locks offer superior protection and long-term reliability.
