How to Choose the Right Deadbolt for Your Front Door
Not all deadbolts are created equal. This guide helps you understand the differences between Grade 1, Grade 2, and Grade 3 deadbolts so you can choose the best option.
Why Your Deadbolt Choice Matters
Your front door's deadbolt is your first line of defense against intruders. But with dozens of options on the market, choosing the right one can be overwhelming. Understanding ANSI/BHMA grades will help you make an informed decision.
Understanding ANSI/BHMA Grades
The American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) test and rate locks on a scale of 1 to 3:
- Grade 1: Highest security, designed for commercial use but ideal for residential front doors.
- Grade 2: Medium security, suitable for interior residential doors.
- Grade 3: Lowest grade, minimal security — not recommended for exterior doors.
Key Features to Look For
Beyond the grade, look for these features:
- Hardened steel bolt: Resists cutting and sawing
- Anti-pick pins: Make lock picking extremely difficult
- Anti-drill plates: Protect against drilling attacks
- Bump-resistant design: Prevents bump key attacks

Smart Deadbolts
Smart deadbolts offer keyless entry via PIN, fingerprint, or smartphone app. They're convenient and add an extra layer of control — you can monitor access remotely and revoke guest codes instantly. However, they should still be Grade 1 rated.
Professional Installation Matters
Even the best deadbolt can fail if improperly installed. Call Provo Locksmith UT at (385) 283-6134 for expert installation that ensures your deadbolt is properly aligned, reinforced, and functioning at peak security.
