Google Nest smart locks

Most smart locks come with all the hardware you need to install them, whether your door has a deadbolt or lever lock. But if you're not a DIY person, you might want to call a locksmith.

Yes, if you want key-free convenience. And many smart locks give you other helpful features, like multiple codes for different users and an activity log. So, if you've got a house with a lot of people coming and going, a smart lock makes it much easier to allow and keep track of access.

You can set unique codes and access windows for different people. That makes it easy to have a code for family members, and other codes for dog-walkers, contractors, or other people who only need temporary access to your house. Some smart locks integrate with other smart home gear like video doorbells, smart lights, and voice assistants. Some also allow “geofencing,” which means that they automatically lock and unlock when you (and your smartphone) come and go.

Like any other password-protected device, a smart lock can theoretically be hacked. But if you're mindful when you set it up, a successful hack is highly unlikely. A key "hidden" under your front door mat might be a more likely invitation to burglary than an encrypted password and security codes that you can change at any time.

Our most affordable smart locks are keypad or touchscreen models that don't need Wi-Fi or any kind of wireless connection. But they also allow you to access expanded features when you add optional Wi-Fi, Z-wave, or other network control. You can also buy a lock with network connectivity built in or a kit with an external network module.
