10 Best Z Wave Door Lock 2026 in the United States

The Kwikset Home Connect 620 is a solid choice if you want a smart Z-Wave door lock with reliable security and easy installation. Its motorized deadbolt offers keyless entry via an illuminated keypad, which is quiet and quick, plus the SmartKey system lets you re-key the lock yourself, adding a handy layer of protection against break-ins. It works seamlessly with popular home automation hubs like Ring Alarm, Samsung SmartThings, and others, but you do need a Z-Wave hub to connect it to your smart home setup. Battery life is quite good, powered by four AA batteries that can last a year or more under normal use, so you won't be changing batteries often.

Installation is straightforward and DIY-friendly, fitting most standard door thicknesses with just a screwdriver. Remote access is possible through compatible hubs and apps, letting you lock or unlock your door from afar, and you can set multiple user codes for family members or trusted guests, which is convenient for managing access. The lock's build feels sturdy with a traditional Venetian Bronze finish that suits many home styles.

If you don’t already have a Z-Wave hub or compatible system, you will need one to benefit fully from its smart features. Also, while it’s compatible with voice assistants like Alexa and Google Assistant, this is through integration with those hubs rather than direct support. This lock is well suited for homeowners wanting a secure, user-friendly smart lock that blends traditional looks with modern technology, especially if they already use or plan to use a Z-Wave smart home system.

Battery life is decent at about 12 months on four AA batteries, included in the package, so you won’t have to worry about frequent changes.

However, remote access depends entirely on having a compatible hub, which adds to the cost if you don’t already own one.
