10 Best Smart Locks 2025 in the United States

The eufy FamiLock S3 stands out with its unique palm vein recognition technology for keyless entry, offering fast and highly accurate unlocking while keeping your biometric data private and secure. This feature makes it a strong choice for anyone prioritizing advanced security without fumbling for keys or codes. It combines a deadbolt lock with a built-in 2K HDR camera and doorbell, providing a wide, clear view of visitors and packages, even in low light conditions.

The lock operates on Wi-Fi and integrates smoothly with popular smart home systems like Apple HomeKit, Amazon Alexa, and SmartThings through the Matter standard. Camera streaming features are accessible via eufy’s dedicated app. Power is reliable with a large rechargeable battery lasting up to four months, supplemented by backup AAA batteries for additional assurance during outages. The lock also includes smart motion sensors to reduce false alarms and an auto-lock function, enhancing both convenience and security.

Installation is designed for front doors and includes all necessary hardware, fitting standard deadbolt setups with a durable stainless steel body. The advanced integration requires a compatible eufy HomeBase 3 hub, which may add to setup complexity and cost. The palm vein scanner offers impressive biometric security, though new users may need a brief adjustment period to become familiar with the technology. This lock is well suited for users seeking a high-tech, versatile smart lock that combines strong security, video monitoring, and broad smart home compatibility in one device.

The eufy Security Smart Lock C220 is a solid choice for front door security, offering multiple ways to unlock your door including fingerprint recognition, app control, keypad, physical key, and voice commands. The fingerprint feature is quick and becomes more accurate over time, which is convenient for frequent use. With built-in Wi-Fi, you can control the lock remotely without needing an extra hub, making it easy to manage access and receive notifications wherever you are. It also integrates nicely with other eufy devices, creating a connected smart home experience.

The lock runs on 8 AA batteries with an estimated life of up to 8 months, which is fairly long for smart locks, though actual battery life depends on usage. Installation is straightforward and compatible with most standard doors in the US and Canada, and it comes with solid customer support and an 18-month protection plan. The design is sleek, combining the deadbolt with a large handleset for a unified, stylish appearance.

On the downside, while the lock is water-resistant with an IP53 rating, it may not be ideal for very harsh outdoor conditions. Also, its smart features work best within the eufy ecosystem, so users relying on other smart home brands might face some limitations. The battery type (alkaline AA) means you will need to replace batteries regularly rather than recharging. Lastly, although it supports voice commands via Alexa and Google Assistant, there is no mention of Apple HomeKit compatibility, which might be a drawback for iPhone users. This smart lock suits homeowners looking for a stylish, easy-to-install solution with versatile access and reliable remote control, especially if they already use or plan to use eufy smart home products.

The eufy FamiLock E34 stands out with its unique palm vein recognition technology, offering a very secure and quick way to unlock your door without keys or codes. This biometric method is highly accurate and stores all data locally, which boosts privacy. It supports multiple smart home systems like Apple Home, Google Home, Alexa, and SmartThings via Matter, making it flexible for different setups. Thanks to built-in Wi-Fi, you can control the lock remotely without needing extra hubs, which many users will find convenient. The battery system is impressive, combining a large rechargeable battery that can last up to 8 months and a smaller backup battery to keep the lock running during power interruptions.

Installation is designed to be easy for typical US and Canadian doors without drilling, which suits most homeowners looking for a DIY solution. The lock is also well-rated for its waterproof design and solid build quality with ANSI/BHMA Grade 1 certification, indicating strong security and durability. On the downside, while palm vein recognition is highly secure, some users may find it less familiar or prefer traditional methods like fingerprint or keypad codes as backups. Also, although the lock supports voice control, the ease of setting this up can vary depending on your smart home ecosystem.

The lock is somewhat bulky at nearly 4 pounds, which might be a consideration for some door types. This lock has no monthly fees, making it cost-effective in the long run, but the initial price and palm vein technology might be higher than more basic smart locks. This product is well-suited for tech-savvy homeowners or those prioritizing advanced security and privacy, especially if they want seamless integration with multiple smart home platforms and are comfortable with premium features.
