Buying Guide
- Keyed Alike vs. Keyed Alike Optional: If you want all four doors to respond to the same key, choose “keyed alike” sets. If you prefer different keys per door, look for “keyed differently” options or separate rekeying options.
- Security Level: ANSI Grade 3 is common for residential use. If you want higher security, look for Grade 1 or Grade 2 options or reinforced deadbolts and anti-saw bolts.
- Backset and Door Thickness: Ensure backset compatibility (2-3/8″ or 2-3/4″) and thickness compatibility (1-3/8″ to 1-3/4″). Reversible latches help with left/right-handed doors.
- Finish and Durability: Matte black and satin nickel finishes are popular for modern homes but check for corrosion resistance in salty or humid environments.
- Installation Ease: DIY-friendly designs with universal backsets and included keys save time. Look for clearly labeled instructions and common-screw placements.
- Finish vs. Function: Aesthetic consistency across doors is a major factor. If function is paramount, prioritize durability (cycle ratings) and anti-tamper features over appearance.
