10 Best Smartthings Lock 2025 in the United States

The Schlage Encode Smart WiFi Deadbolt is a solid choice if you're looking for a secure, keyless smart lock for your front door. It connects directly to your home WiFi without needing extra hubs, making it easy to control and monitor remotely via the Schlage Home app. You can create up to 100 unique access codes, which is handy if you often have guests or service people needing temporary entry. Voice control works with Alexa and Google Home, offering convenient hands-free locking and unlocking.

Security-wise, it features an encrypted connection, a built-in alarm for forced entry, and a fingerprint-resistant touchscreen, which adds extra protection. The lock is battery-powered using four AA batteries, lasting around six months with typical use, and provides low-battery alerts both on the lock itself and in the app. Installation is straightforward and doesn’t require wiring—just a screwdriver and the lock fits most standard doors. One nice perk is its integration with Airbnb, which simplifies guest access by automatically sending temporary codes during bookings.

The lock’s battery life, while decent, means you'll need to keep an eye on replacing batteries to avoid lockouts. Also, relying on WiFi means the lock’s smart features depend heavily on a stable internet connection. While installation is easy for most, those less comfortable with tools might still need some help. This lock is well suited for homeowners wanting a reliable, feature-rich smart lock with strong security and easy remote access, especially if you appreciate voice commands or frequently welcome guests.

The Yale Security Assure Lock 2 Deadbolt is a solid choice if you want a smart lock that offers various ways to unlock your door without a key. You can use the keypad, your smartphone app, voice assistants like Alexa or Google Assistant, or even an auto-unlock feature that senses when you approach. It connects via 2.4 GHz Wi-Fi and Bluetooth, letting you control it remotely, check its status, and share access with others easily through the Yale Access App. Installation is straightforward since it replaces your existing deadbolt with just a screwdriver—no professional help needed, which is great if you’re not very handy. The lock also has an Auto-Lock function that secures your door automatically when closed, enhancing your peace of mind.

On the security side, it supports passcode unlocking and notifies you about battery levels to avoid surprises. However, it requires AAA alkaline batteries, which will need occasional replacement, and it only works reliably in the U.S. and Canada on the 2.4 GHz Wi-Fi band, so check your Wi-Fi setup before buying. Compatibility with major smart home platforms is a plus, but if you use a 5 GHz network or live outside supported regions, this could be a downside. This lock combines convenience and smart features effectively for typical front doors and is best suited for users who want a keyless, app-controlled lock with easy DIY installation.

The Aqara Smart Lock U100 stands out in the smart lock category, especially for users looking for advanced keyless entry options. One of its strongest features is the integration with Apple Home, allowing users to unlock the door with their iPhone or Apple Watch, even when the devices are out of battery. This is a significant convenience for Apple users, making it a great choice for those already within the Apple ecosystem.

The fingerprint unlock feature is another highlight, accommodating up to 50 fingerprints, which is ideal for families or shared living situations. Users can also set remote passwords and even one-time access codes for guests, enhancing its versatility. The auto-lock feature adds an extra layer of security, ensuring that the door locks automatically after closing.

It's important to note that the lock requires an Aqara Zigbee 3.0 hub for full functionality, which could be a drawback for those not already invested in that system. Additionally, while it offers a mechanical key for emergencies, relying on electronic access could be a concern for some users who prefer traditional locking methods.

In terms of durability, the U100 has an IP65 weatherproof rating, making it suitable for various climates, and it boasts a long battery life of up to 8 months, powered by standard AA batteries. It also includes a USB-C port for emergency charging, which adds to its practicality.

While the lock has many advanced features, some users may find the installation process a bit complex if they are not comfortable with DIY tasks. It's designed for screw-in installation, which might require some tools and careful handling.

The Aqara Smart Lock U100 is an excellent choice for those looking to enhance their home security with smart technology, especially Apple users. However, potential buyers should consider its reliance on additional hubs and their comfort level with installation.
