Buying Guide
- Do you need exterior security or interior privacy? Separate exterior entry locks from interior privacy knobs when possible to optimize function and cost.
- What backset and thickness do you have? Most units support 2-3/8″ or 2-3/4″ backsets and 1-3/8″ to 1-3/4″ door thickness; confirm before purchase.
- What level of keying is required? Options range from keyed-alike sets to keys and smart access. For shared entrances, consider keyless or biometric options with a mechanical fallback.
- Are you prioritizing installation speed? Many models promise 5-minute installation with preinstalled screws and standard hardware.
- Finish and material matter beyond aesthetics. Satin stainless, matte black, and brass/brass-like finishes affect durability, fingerprints, and compatibility with decor.
FAQ
- What is backset, and why does it matter? Backset is the distance from the edge of the door to the center of the bore hole. Most residential doors use 2-3/8″ or 2-3/4″. Choose a lock that fits your backset to ensure proper fit.
- Are privacy interior knobs secure for bedroom doors? They provide privacy with a turn-button lock, but are not designed to secure against forced entry from the outside.
- Do these locks require professional installation? Most items listed claim easy DIY installation with standard tools, though some preferences may benefit from professional help for precise alignment.
- Can I mix finishes on the same door? Yes, but ensure hardware complements the door’s style and the home’s overall hardware aesthetic.
- What if I forget to register administrator access on a smart lock? Some models require administrator setup before use; without it, many functions may be inaccessible until configured.
