ANSI/BHMA grading shows up on lock packaging constantly, but most shoppers have no idea what the number actually measures. Here's the plain version.
What Gets Tested
ANSI/BHMA 156.2 (the residential and commercial lock standard) evaluates cycle testing (how many times the lock can be operated before failing), strength testing (resistance to force, impact, and torque), and security testing (resistance to picking and manipulation).
Grade 1
The highest residential rating, technically the commercial-grade standard. Best cycle life, strongest resistance to force and manipulation. Worth it for primary entry doors.
Grade 2
Solid mid-tier performance, a reasonable choice for secondary doors or budget-conscious upgrades that still want real durability.
Grade 3
The minimum standard, what most builder-grade tract homes ship with by default. Functional, but the least durable and least resistant of the three.
Does the Grade Number Actually Matter?
Yes, meaningfully. A Grade 1 lock isn't just marketing, it genuinely withstands more force and lasts longer under daily use. See why cheap locks can cost you more for the long-term cost math.
Where to Check the Grade
It's usually printed on the packaging or spec sheet, if you're not sure what's currently on your door, we can identify it during a service visit.
