As a supplier of ANSI Commercial Mortise Locks, I often encounter questions from customers regarding the security features of these locks, especially their resistance to picking. In this blog post, I'll delve into the technical aspects of ANSI Commercial Mortise Locks and explore their effectiveness against picking attempts.
Understanding ANSI Commercial Mortise Locks
ANSI (American National Standards Institute) Commercial Mortise Locks are designed to meet specific standards for commercial applications. These locks are typically installed in a pocket, or mortise, that is cut into the edge of a door. They are known for their durability, strength, and high - security features, making them a popular choice for commercial buildings, offices, and other high - traffic areas.
The construction of ANSI Commercial Mortise Locks involves high - quality materials such as brass, steel, and other alloys. These materials not only provide physical strength but also contribute to the lock's ability to resist various forms of attack, including picking.
How Picking Works
Lock picking is a technique used to open a lock without the original key. It involves manipulating the lock's internal components, such as pins or tumblers, to align them in a way that allows the lock to be opened. There are several methods of picking, including single - pin picking, raking, and bumping.
Single - pin picking is a precise method where the picker uses a pick tool to manipulate each pin or tumbler in the lock one by one until they are all aligned at the shear line. Raking, on the other hand, is a faster but less precise method where the picker uses a rake tool to quickly move multiple pins or tumblers at once, hoping to align them randomly. Bumping involves using a specially - designed key and a hammer or other striking tool to create a shockwave that causes the pins or tumblers to jump into the correct position.
Resistance of ANSI Commercial Mortise Locks to Picking
High - Quality Pin and Tumbler Systems
Most ANSI Commercial Mortise Locks feature advanced pin and tumbler systems. These systems are designed with multiple pins of different lengths and configurations, making it more difficult for a picker to align them correctly. The pins are often made of hardened materials that resist bending or breaking during a picking attempt.
Moreover, some ANSI Commercial Mortise Locks use spool pins or serrated pins. Spool pins have a non - circular shape, which makes it difficult for a picker to lift them to the correct position. Serrated pins have ridges that catch on the pick tool, preventing smooth movement and making the picking process more time - consuming and challenging.
Security - Enhanced Keyways
The keyway of an ANSI Commercial Mortise Lock is another important factor in its resistance to picking. Many of these locks have complex keyways that are designed to prevent unauthorized access. The shape of the keyway can be unique, with irregular cuts and contours that make it difficult for a picker to insert a pick tool or a makeshift key.
Some ANSI Commercial Mortise Locks also feature sidebar mechanisms. A sidebar is an additional security component that must be moved into the correct position before the lock can be opened. This adds an extra layer of complexity to the lock's operation and makes it much more difficult to pick.
Anti - Bumping and Anti - Raking Features
To combat bumping and raking, ANSI Commercial Mortise Locks often come with anti - bump and anti - rake features. These features can include special springs, pins, or other internal components that are designed to prevent the pins or tumblers from being easily moved by a shockwave or a rapid movement.
For example, some locks have a spring - loaded pin system that resists the force of a bumping attempt. When a bumping force is applied, the springs compress and prevent the pins from jumping into the correct position. Similarly, anti - rake features can prevent the rake tool from easily moving the pins or tumblers, as they are designed to catch or resist the tool's movement.
Testing and Certification
ANSI has established standards for the security of commercial locks, including mortise locks. Locks that meet the ANSI standards have undergone rigorous testing to ensure their resistance to various forms of attack, including picking.
The testing process typically involves subjecting the lock to a series of picking attempts using different techniques and tools. The lock must withstand a certain number of picking attempts within a specified time frame to pass the test. Locks that meet the ANSI standards are certified, which provides customers with assurance of their security performance.
Real - World Performance
In real - world scenarios, ANSI Commercial Mortise Locks have proven to be highly effective in preventing unauthorized entry through picking. Their high - quality construction, advanced security features, and compliance with industry standards make them a reliable choice for protecting commercial properties.
However, it's important to note that no lock is completely immune to picking. Skilled and determined pickers may still be able to find ways to bypass a lock, especially if they have access to advanced tools and techniques. But the time and effort required to pick an ANSI Commercial Mortise Lock are significantly greater compared to lower - quality locks, which acts as a strong deterrent.
Choosing the Right ANSI Commercial Mortise Lock
When choosing an ANSI Commercial Mortise Lock, it's important to consider several factors. Look for locks that are certified to meet the relevant ANSI standards. The higher the ANSI grade, the greater the security level of the lock.
Also, consider the specific needs of your application. For example, if your building is in a high - crime area or has a high - value inventory, you may want to choose a lock with additional security features such as a high - security key system or a deadbolt.
Conclusion
In conclusion, ANSI Commercial Mortise Locks are highly resistant to picking due to their advanced design, high - quality materials, and compliance with industry standards. Their complex pin and tumbler systems, security - enhanced keyways, and anti - bump and anti - rake features make them a formidable barrier against unauthorized entry.
