Buying Guide: Key Purchase Considerations
Security and privacy
Look for features like tamper alerts, duress or anti‑peep codes, and secure Bluetooth/Wi‑Fi communications. Check BHMA/ANSI ratings for mechanical robustness and tamper resistance. A reputable ecosystem with regular firmware updates helps maintain security over time.
Unlock methods and convenience
Consider how you primarily enter your home: biometrics (fingerprint or palm vein), keypad codes, app control, or voice commands. A model with multiple options offers redundancy and flexibility for different household members, deliveries, and guests.
Power and reliability
Battery life varies by model. Look for locks with long battery life, built‑in low‑battery alerts, and emergency power options (USB or backup keys). Built‑in Wi‑Fi or a bridge affects how you connect remotely; some devices work directly on Wi‑Fi while others require a hub.
Smart home compatibility
Ensure the lock works with your preferred voice assistants (Alexa, Google Assistant, or Apple HomeKit) and integrates with your existing smart home routines. Consider whether you want on‑device codes, temporary guest access, or automation with door sensors and cameras.
Installation and compatibility
Retrofits (like August) can be quick for some doors, while others may require contractors. Check door thickness, deadbolt type, and backset compatibility. Consider installation time, tools needed, and whether you’ll need to replace strike plates or cutouts.
Price and value
Prices vary with features such as AI fingerprinting, palm recognition, multi‑unlock options, and integrated ecosystems. Evaluate which features deliver the most value for your household’s usage patterns and security needs.
