The right smart lock depends on your door type, installation preference, smart home ecosystem, security needs, and how you want to access your home.
Installation Type
Some smart locks replace your existing deadbolt with a fully motorized unit that works with your existing key. Others retrofit over your existing deadbolt interior, leaving your exterior keyway unchanged.
Access Methods
Smart locks offer various access options including keypad codes, smartphone app, Bluetooth, Wi-Fi, fingerprint, and traditional keys. Choose based on who needs access and how often you want to provide it.
Smart Home Compatibility
Consider whether the lock works with your preferred smart home platform such as Apple HomeKit, Google Home, Amazon Alexa, or Samsung SmartThings for automation and voice control.
Power and Battery Life
Battery life varies from months to over a year. Look for low-battery alerts and consider locks with backup power options such as a 9-volt battery contact or physical key backup.
