We keep seeing ANSI grade referenced when shopping for deadbolts — what does that designation actually mean in practical terms?
ANSI stands for the American National Standards Institute, and a lock's ANSI grade tells you how it performed across standardized tests measuring durability, forced entry resistance, and operational reliability — it's one of the most useful objective signals available when comparing hardware. Sundial Locksmith stocks and installs ANSI-rated hardware for Tempe properties and can explain exactly what each tier means for your specific door and use case.
