Buying Guide
What to consider when choosing a double keyed deadbolt:
- Keying arrangement: Do you want keys working on both sides identically (keyed alike) or unique keys per bolt? Decide based on how many doors you want to share keys with and security needs.
- Backset and door thickness: Verify your door’s thickness and backset (2-3/8″ or 2-3/4″) to ensure proper fit and function. An adjustable backset helps with multiple door standards.
- Finish and hardware compatibility: Choose a finish that matches your door hardware (stainless, satin nickel, matte black) for a cohesive look and durability.
- Security features: Look for anti-pry, anti-collision designs, and robust latches or cylinders to resist forced entry.
- Installation: Some models emphasize easy installation with snap features; others require standard screw mounting. Ensure you have the necessary tools and drills for your door’s drill pattern.
- Warranty and certifications: While not specified here, consider products with strong warranties and recognized security ratings (ANSI/BHMA) for long-term reliability.
