Buying Guide: Key Purchase Considerations
- Security level: Double cylinder deadbolts offer key access on both sides, reducing the risk of forced entry compared to single-cylinder variants that only require a key on the exterior.
- Finish and hardware compatibility: Choose finishes (satin nickel, polished brass, etc.) that match existing door hardware and architectural style.
- Keying options: Keyed-alike sets simplify access with a single key for multiple locks, while non-alike options can offer separate keys for different doors or zones.
- Backset and door thickness: Ensure the chosen lock supports common backsets (2-3/8″ or 2-3/4″) and door thickness (1-3/8″ to 1-3/4″).
- Installation: Look for DIY-friendly installation that uses standard screw placements and pre-drilled doors; some models include clear instructions and fewer specialized tools.
- Durability and compliance: ANSI Grade 1 or 3 ratings indicate higher resistance to wear and tampering; stainless steel or hardened components improve longevity.
- Re-keying ability: Some models offer Quick Key or SmartKey-style re-keying to maintain security without replacing hardware.
- Maintenance: Finishes with better corrosion resistance perform longer in humid or coastal environments; clean with recommended methods to preserve appearance.
- Key management: For multi-door setups, decide whether to use a single key across all locks or multiple keys, balancing convenience and access control.
