Buying Guide: Key Purchase Considerations
Privacy level and use-case: Choose privacy levers or knobs for bedrooms and bathrooms, or keyed entry if you need added exterior-style security for a secondary interior door. Consider whether you prefer a traditional mechanical lock or a smart option with biometric or app access.
Door compatibility: Verify door thickness (typically 1-3/8″ to 1-3/4″) and latch backset (2-3/8″ or 2-3/4″) to ensure proper fit. Reversible handles help if door handing varies in your home.
Durability and finish: Satin nickel and matte black are common, durable finishes that resist wear in high-traffic spaces. All-metal constructions generally offer greater longevity in interior doors.
Ease of installation: DIY-friendly models with preinstalled screws or clear instructions save time. Self-aligning screw holes and included tools enhance install success for homeowners with basic handiness.
Safety and hygiene: Privacy levers and antimicrobial coatings can help reduce touching surfaces. For shared spaces, a privacy lock with inside/outside release tools adds convenience without compromising safety.
Smart features: If you want touchless or biometric access, ensure compatibility with your devices and Wi-Fi, and check user limits (fingerprints, codes) and automatic locking behavior for daily routines.
