The Basics of Lock Grading

Lock grading is a standard established by the American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) to evaluate the durability, strength, and security level of door locksets and deadbolts. The system categorizes locks into three grades:

The highest level of security available, Grade 1 locks are typically used in commercial settings but can also be used in residential settings for maximum security. These locks have the strongest and most durable construction, designed to withstand significant force and high volumes of use.

Offering a good balance between security and cost, Grade 2 locks are suitable for light commercial use and higher-security residential applications. They are durable and reliable, designed to offer a substantial level of security without the premium cost of Grade 1 locks.

The lowest security rating, Grade 3 locks are standard for residential properties. While they provide basic security and meet minimum ANSI standards, they are not as resistant to force or as durable as Grade 1 or Grade 2 locks.

How Lock Grading Affects Security

The lock grading system directly correlates to a lock’s ability to resist tampering, picking, and physical force. Here’s how the grading system affects security:

Resistance to Physical Attack: Grade 1 locks are tested to withstand more forceful attacks and attempts at forced entry. They have stronger bolts, more secure strike plates, and are generally made from more durable materials.

Lifespan and Durability: Higher-grade locks are also tested for durability, including the number of lock/unlock cycles they can endure. Grade 1 locks are required to last for a significantly higher number of cycles compared to Grade 3 locks, making them a better long-term investment.

Resistance to Lock Picking and Bumping: Locks are assessed for their resistance to picking, bumping, and other bypass methods. Grade 1 and Grade 2 locks typically offer more complex and secure locking mechanisms that are harder for burglars to compromise.

Choosing the Right Lock for Your Home

When selecting locks for your home, consider the following:

Entry Points: High-risk entry points, such as front and back doors, may benefit from Grade 1 or Grade 2 locks for enhanced security. Less vulnerable areas, like interior doors or low-access exterior doors, might be adequately secured with Grade 3 locks.

Budget: While Grade 1 locks offer the highest level of security, they also come with a higher price tag. Balance your budget with your security needs, potentially opting for Grade 2 locks as a compromise that doesn’t sacrifice significant security.

Home Security System: If you have a robust home security system in place, you might choose to complement it with Grade 2 locks, balancing overall security with cost-effectiveness.
