What to Look For
Entry Methods
Look for at least two ways in: fingerprint, passcode, app, or key. More options help when your phone dies or your hands are full.
Alexa and Smart Home Compatibility
“Works with Alexa” can mean a skill, a routine, or a full Matter setup. Check the exact model, the app, and whether you need a hub or border router.
Wi-Fi and Hub Needs
Most locks here use 2.4 GHz Wi-Fi and do not need a hub for basic remote control. Matter over Thread models need a compatible Thread border router. Not sure if a smart lock needs a hub? Our guide on do smart locks need a hub explains the difference.
Power and Battery Backup
All of these locks are battery-powered. Look for low-battery alerts, USB-C backup, and at least one mechanical key.
Installation and Door Fit
Check door thickness, backset, and deadbolt alignment. Some locks are for interior doors only.
Security Alerts and Access Control
Auto-lock, door sensors, activity logs, and temporary codes reduce risk. A smart lock helps manage access; it does not replace 911.
