Buying Guide
What should you consider when choosing exterior door locks?
- Keying and convenience: Decide if you want all components keyed alike or a set that allows separate rekeying. Keyed-alike simplifies access for multiple family members or roommates but limits future key changes.
- Door preparation and fit: Ensure latch backset (2-3/8″ or 2-3/4″), bore size, and door edge preparations match the product specs. Some sets require precise alignment for smooth operation.
- Material and finish: Look for durable metals (brass, steel) and finishes that resist corrosion and match your exterior trim (e.g., Matte Black, Satin Nickel).
- Weather resistance: For exterior doors, choose locks designed to withstand moisture, temperature changes, and salt air if you’re near the coast.
- Installation simplicity: DIY-ready sets include all screws and mounting hardware; others may need separate purchase or professional help.
- Security features: Consider deadbolt strength, anti-pick features, and how many keys are provided. A single-cylinder deadbolt is common but ensure proper exterior security needs.
Key considerations by scenario
- First-time installation on a new door: Look for all-in-one sets with clear bore hole compatibility and included screws, as seen in several entries.
- Upgrading an old lock: Prioritize keyed-alike compatibility with existing hardware to minimize changes to door prep.
- Rental properties: Favor sets with easy rekey options or simple key management for multiple tenants.
