While shopping for new locks, you may notice that each lock has a lock grade. These grades come from the ANSI/BHMA grading system. This grading system is used for locks produced and sold within the United States and Canada. It tells you the overall performance of the lock and helps you choose the right lock for your home.

The Different Types of Lock Grades

There are three different lock grades, which include:

ANSI Grade 1- This is a heavy-duty commercial security lock. It is specifically designed for high traffic and superior security. As the strongest grade, it can be used for residential applications too, but it is predominantly found in commercial and industrial applications.

ANSI Grade 2- This is a high residential security or low commercial grade. It is designed to offer superior security and durability for homes and light commercial use.

ANSI Grade 3 - This is a basic residential security lock that meets the lowest acceptable quality standards for locks by the ANSI.

Knowing How to Choose the Right Lock

It is best to consult a locksmith in Aurora to find the perfect lock for your application. Locks, regardless of their grades, come in a variety of forms including:


Keyed Entry Knobs and Levers


Naturally, if you have a business, you will want to use a Grade 1 lock. This offers maximum security and durability, so you can thwart any professional burglary attempts. For interior doors, a business can also use a Grade 2 lock. Homes, on the other hand, can use Grades 1 through 3, all depending on the amount of security they want. For entry doors, homeowners may want to use a Grade 1 lock to achieve maximum security; though most homes use Grades 2 and 3.
