ANSI Grade 1, 2, 3 Locks Explained for Denver, NC Homes
Q: What's the difference between Grade 1, 2, and 3 locks?
ANSI grades measure how a lock performs in standardized tests for cycles, strength, and security. Grade 1 is commercial-strength, Grade 2 is heavy residential, Grade 3 is basic residential.
Most Denver, NC homes ship with Grade 3 locks from the builder. Upgrading exterior doors to Grade 1 deadbolts — readily done in a single Denver, NC locksmith visit — meaningfully improves break-in resistance.
Grade 2 is fine for interior or low-priority doors. Grade 1 belongs on every exterior door of a Denver, NC home. For commercial properties on NC-16 or NC-73, Grade 1 is essentially mandatory.
Brand matters less than grade. A Grade 1 Schlage, Yale, or Medeco installed correctly by a Denver, NC locksmith outperforms any Grade 3 brand on the shelf.
