Buying Guide
- Keyed Alike vs. Keyed Different: Keyed-alike sets enable using a single key across multiple locks. Consider this when you want convenient access for family members or staff, but balance with the need for compartmentalized access if you have guests or service providers.
- Grade and Security: Look for ANSI Grade 3 or higher for exterior doors, which indicates better durability and resistance to wear and tampering. Double-cylinder deadbolts add an extra layer of security for doors with glass or vulnerable panels nearby.
- Finish and Compatibility: Matte black, satin nickel, and polished brass finishes offer different aesthetics. Ensure the latch backset (2-3/8″ or 2-3/4″) and door thickness compatibility align with your doors (generally 1-3/8″ to 1-3/4″ thick).
- Installation and Maintenance: Choose sets that include mounting screws and clear installation instructions. Stainless steel components resist corrosion in humid climates, extending the life of the hardware.
- Exterior vs. Interior Use: Exterior doors benefit from more robust deadbolts and weather-resistant finishes, while interior doors may prioritize ease of use and design cohesion with existing hardware.
- Key Management: If you prefer having a single key across multiple doors, ensure the product specifies keyed alike and confirm whether rekeying is supported if you replace one lock later.
- Cost and Coverage: While prices aren’t listed here, compare total set contents (knobs, deadbolts, latches) and warranty terms to determine long-term value and coverage for multiple doors.
