Buying Guide
What ANSI Grade Do I Need?
ANSI Grade 3 locks offer a balance of security and cost for residential use. They are generally recommended for exterior doors and shared entries in moderate-risk environments. If your property faces higher risk or you need municipal compliance, you may consider Grade 1 options.
Keyed Alike Or Individual Cylinders?
Keyed-alike systems simplify access when multiple doors share the same key. They are convenient for families or small offices but consider future lock changes if anyone’s access needs to be restricted.
Installation and Backset Considerations
Most sets fit standard backsets (2 3/8″ or 2 3/4″). Check door thickness (typically 1 3/8″ to 2″) and backset compatibility before purchase to ensure a clean install.
Durability and Materials
Look for brass cylinders or corrosion-resistant steel for longevity. Finishes (satin nickel, brushed chrome, satin stainless) affect maintenance and appearance. Weather exposure should guide exterior versus interior placement.
Security Features To Look For
Anti-saw bolts, tamper-resistance, and reliable latching mechanisms improve protection. Containers with higher usage simulations suggest more durable performance under daily wear.
Compatibility With Existing Hardware
Measure existing strike plates and backsets to avoid mismatches. Some sets require specific door preparations or improved mounting hardware for a secure fit.
