What to look for when buying a smart lock?

What to look for when buying a smart lock includes physical security, compatibility, connectivity, and convenience features. First check BHMA Grade, Grade 1 is strongest, Grade 2 good residential, avoid Grade 3 for entry doors. Check door compatibility, measure thickness, backset, bore hole, and ensure door is solid and aligned. Choose connectivity, Bluetooth only for longer battery and privacy, WiFi built in for remote access, or Z-Wave Zigbee if you have hub, best is dual Bluetooth plus WiFi bridge. Look for access methods, keypad code, fingerprint, app, Apple Home Key, physical key backup, and ability to create temporary guest codes. Check battery type and life, AA batteries easy to find, rechargeable pack convenient, and emergency power option like USB-C. Look for security features, AES encryption, two factor authentication, tamper alarm, auto lock, and activity logs. Check smart home integration with Alexa, Google Home, HomeKit, and Matter support. Consider design and finish matching door hardware. Read warranty and brand reputation, Schlage, Yale, August have strong support. Finally consider price versus subscription, some require subscription for features. Choose lock that balances Grade 1 security, long battery, multiple access methods, and strong encryption.
