Buying Guide: Key Purchase Considerations
- Grade and Certification: Look for ANSI/BHMA Grade 1 certification or equivalent, indicating top-tier security, durability, and finish performance suitable for exterior doors.
- Backset and Fit: Check backset options (2-3/8″ or 2-3/4″) and cross bore compatibility to ensure a proper installation on your door.
- Security Features: Prioritize anti-pick pins, hardened steel components, anti-drill plates, and robust locking mechanisms. Some models offer additional anti-bump features for enhanced protection.
- Finish and Aesthetics: Choose a finish that complements your door color and hardware style (satin nickel, matte black, brass, etc.) while maintaining corrosion resistance.
- Fire and Durability Ratings: For commercial or high-traffic areas, consider models with UL fire ratings and corrosion-resistant steel builds for longer service life.
- Keying Options: Decide between keyed, double-sided keyed, or non-keyed options based on entry requirements and convenience. Some models include two keys for convenience and redundancy.
- Installation and Compatibility: Verify whether the lock is compatible with your door thickness and bore pattern. Some units are designed for two-bore doors common on residential entryways.
- Maintenance: Grade 1 deadbolts typically require minimal maintenance, but periodic lubrication and inspection of strike plates can extend life and security.
- Smart vs. Mechanical: If you prefer smart features (remote access, logging, auto-lock), consider smart deadbolts with compatible systems, ensuring they meet Grade 1 security standards where applicable.
