Security Certifications and Testing Standards
Locks are often rated according to recognized security standards, which directly influence pricing. Professional-grade locks may meet higher ANSI or BHMA security grades, meaning they have passed durability and forced entry testing. These tests simulate repeated use cycles and attack attempts. Lower-priced locks typically meet minimal standards suitable for light residential use, while higher-priced locks are designed for heavier use or higher-risk environments. These standards also influence residential lock installation cost and commercial lock cost because stronger hardware often requires professional installation.
