Buying Guide: Key Purchase Considerations
- Keyed alike vs. keyed different: Keyed-alike sets reduce key management by using one key across all locks, ideal for homes with multiple entry points.
- Finish and matching: Choose finishes (satin nickel, matte black, brushed nickel) that complement your exterior and interior hardware for a cohesive look.
- Security level: Look for ANSI Grade 3 or higher, and features like anti-saw bolts and high-cycle durability to withstand daily use.
- Door compatibility: Verify backset, latch size, and door thickness (most sets fit standard doors; some specify 1.38″ to 1.77″ thickness).
- Installation: Many 4-pack sets are designed for DIY installation with common tools; ensure clear mounting templates and included hardware.
- Maintenance: Consider finishes with corrosion resistance and rust protection if you live in humid or coastal areas.
- Warranty and support: Look for products offering a solid warranty and accessible customer support for potential issues.
