Buying Guide
Key purchase considerations help match a door lock set to your door type and security needs.
- Matte black finishes look modern and resist corrosion when paired with good hardware materials (stainless steel, brass). Consider electroplated finishes for rust resistance in salty or humid climates.
- Keying options: Keyed-alike sets simplify access across multiple doors. If you have several entrances, a keyed-alike configuration reduces key clutter but may reduce customization per door.
- Security features: Look for robust latches, anti-saw bolts, and tamper-resistant cylinders. SmartKey or re-keyable options enable quick key changes without changing hardware.
- Door compatibility: Confirm door thickness (usually 1-3/4″ standard) and backset (2-3/8″ or 2-3/4″) before selecting a set. Ensure bore hole size matches the lock body.
- Installation considerations: Reversible handles accommodate left- or right-opening doors. DIY installation is common for most exterior lock sets, but some assemblies may require extra tools.
Frequently Asked Questions

- Is SmartKey a better option than standard keyed sets? SmartKey allows quick re-keying without locksmiths, improving flexibility if you lose keys or add new doors.
- Which finish lasts longest in coastal areas? Matte black finishes combined with stainless steel components typically perform well, but ensure the product uses corrosion-resistant hardware.
- Can I install these myself? Most exterior lock sets are designed for DIY installation with common tools. Always follow product-specific instructions for latch backset and borehole alignment.
