7 Best Eufy Door Locks of 2026

The eufy C220 punches well above its weight for budget-conscious smart home adopters. With built-in Wi-Fi and six unlock methods, including sub-1.5-second fingerprint access, this deadbolt delivers core smart functionality without complexity. Its self-learning AI improves recognition over time, eliminating the frustration of repeated swipes—a common pain point for families with kids or elderly members. For those seeking a no-fuss, no-bridge-required upgrade to keyless entry, the C220 offers remarkable value right out of the box.

In real-world use, the C220 shines with consistent performance across daily unlocks and remote control via the eufy Security app. The 8-month battery life on standard AAs means fewer interruptions, and the IP53 rating ensures resilience against moisture and dust at exterior doors. It handles frequent use with ease and sends real-time alerts for lock/unlock events, ideal for monitoring comings and goings. However, it lacks auto-lock scheduling and advanced integrations like Matter, which may limit expansion for future-proof setups.

Compared to higher-end models like the FamiLock S3 Max, the C220 trades premium biometrics and camera features for simplicity and affordability. It’s best suited for renters or homeowners wanting reliable, app-controlled access without overspending. While it doesn’t offer palm vein scanning or built-in video, it delivers essential smart lock performance at a fraction of the cost—making it a standout for those prioritizing function over flash.

Step into the future of home security with the eufy FamiLock S3 Max, where palm vein recognition redefines access control. This all-in-one powerhouse combines a BHMA Grade 1 deadbolt, a 2K HDR doorbell camera, and a rear video screen into a single, seamless system. Unlocking in 0.6 seconds with 99.9% accuracy, the palm scanner is virtually impossible to spoof—making it a game-changer for high-security homes. Add in 150° head-to-toe visibility and local 16GB storage, and you’ve got a fortress-grade entry solution that keeps your data private.

Performance-wise, the S3 Max excels in both security and convenience. The dual power system—a rechargeable battery plus AAA backup—ensures uninterrupted operation, while the rear video screen lets kids or seniors check visitors without a smartphone. The f/1.6 lens captures crisp night footage, and real-time alerts keep you in the loop. However, the camera doesn’t stream via Matter yet, so full functionality still requires the eufy app, which may frustrate users seeking full ecosystem independence.

When stacked against the E31 or C220, the S3 Max is in a different league—offering integrated surveillance and biometric access in one unit. It’s ideal for families wanting total front-door awareness and touchless entry, especially those with aging parents or young children. Though pricier, it justifies every dollar with cutting-edge palm recognition and built-in video, outperforming simpler models that require separate doorbell setups.

The eufy C33 is the rare smart lock that blends elegant design with practical biometrics, tailored for doors with handles. Its fingerprint-enabled door knob unlocks in a grip-and-turn motion, making entry feel natural and fast—perfect for busy households. With built-in Wi-Fi, you can manage access remotely, receive real-time alerts, and review event history, all without a hub. This lock solves the awkwardness of juggling keys with kids or groceries, delivering effortless one-touch access for every family member.

In testing, the C33 proved reliable on both front and interior doors, with smooth integration into the eufy app and solid IP53 weather resistance for exterior use. The 8 AA batteries offer predictable power life, and the 15-minute installation fits most standard doors without drilling. However, it lacks auto-lock and Matter support, and the fingerprint sensor, while fast, isn’t as adaptive as AI-driven models like the S230. It’s best for users who want handle-mounted convenience without advanced automation.

Compared to the C220, the C33 fills a niche: it’s the only model here designed specifically for doors with handles, unlike deadbolt-only alternatives. It’s less about raw innovation and more about ergonomic smart access where traditional knobs dominate. While it doesn’t match the security depth of palm vein models, it delivers intuitive, family-friendly performance—a smart upgrade for homes wanting handle-based fingerprint control.

The eufy S230 is engineered for speed and simplicity, delivering lightning-fast fingerprint unlocking in under 0.3 seconds thanks to its AI self-learning sensor. With a massive 10,000 mAh battery, it promises up to a year of use—dramatically reducing maintenance compared to AA-powered models. BHMA certification confirms its durability after 100,000 cycles, and IP65 weatherproofing makes it ideal for harsh climates. For users who hate charging or replacing batteries, this lock is a low-maintenance powerhouse.

Real-world testing confirms its reliability: the large fingerprint sensor adapts quickly, even with wet or cold hands, and built-in Wi-Fi enables seamless remote access and notifications. Installation takes under 15 minutes with no drilling, and the app provides clear access logs and user management. However, it lacks auto-lock scheduling and Matter compatibility, limiting smart home expansion. It’s best for users who prioritize battery longevity and fast biometrics over deep automation.

Against the E31, the S230 offers similar battery life but falls short in ecosystem integration—it doesn’t support Apple Home natively. Still, it outshines budget models like the C220 with superior weather resistance and unlock speed. It’s the top pick for those wanting a set-and-forget smart lock that’s tough, fast, and easy to install—perfect for main entry doors in variable weather.

The eufy E31 is the marathon runner of smart locks, boasting up to 14 months of battery life on a single charge—thanks to its 10,000 mAh powerhouse battery. But it’s not just about endurance; this lock delivers ultra-fast 0.3-second fingerprint access, auto-lock automation, and native Matter support, making it a future-proof hub for smart homes. With seamless integration into Apple Home, Google, and Alexa, it lets you unlock the door with voice or automations—solving the “did I lock the door?” anxiety once and for all.

In daily use, the E31 impresses with reliability and flexibility. The local fingerprint storage ensures privacy, while remote access via HomePod adds convenience for Apple users. Real-time alerts and event logs keep you informed, and the power-save mode extends usability even when the battery drops to 20%. However, emergency power requires a portable charger (not for charging), which feels like a missed opportunity for USB-C passthrough.

Compared to the S230, the E31 offers longer battery life and critical smart home compatibility, making it better for automation enthusiasts. While the FamiLock S3 Max has more features, the E31 strikes the ideal balance between battery life, security, and ecosystem integration. It’s the best choice for users who want long-term reliability with full Matter and Apple Home support—a true set-and-forget smart lock.

Security doesn’t get much tighter than the eufy FamiLock E34, which uses palm vein recognition to unlock in just 0.6 seconds with 99.9% accuracy. This forgery-proof biometric system reads your internal vein patterns—impossible to replicate with photos or fake fingers—making it one of the most secure consumer smart locks available. With ANSI/BHMA Grade 1 certification, IP65 waterproofing, and auto-lock, it’s built for maximum durability and peace of mind. For high-risk homes or privacy-focused users, this is fortress-level protection.

Performance is rock-solid: the dual battery system—10,000 mAh primary and 750 mAh backup—ensures continuous operation, even during outages. Built-in Wi-Fi allows remote access and real-time alerts, and Matter support enables smooth integration with Apple Home and Alexa. The app is intuitive, and local data storage keeps your biometrics private. However, it lacks a rear video screen or camera, so you’ll need a separate doorbell for visual verification.

Stacked against the S3 Max, the E34 trades camera features for superior mechanical security and battery redundancy. It’s ideal for users who want maximum biometric protection without monthly fees or cloud dependencies. While the Video Smart Lock E330 offers more visibility, the E34 wins on pure security and reliability, making it the ultimate choice for those who prioritize unbreakable access control over multimedia features.

The eufy Video Smart Lock E330 is the ultimate all-in-one front door guardian, merging a 2K HD camera, video doorbell, and fingerprint smart lock into a single sleek unit. With 8GB of built-in storage, it records footage without subscriptions, and the f/1.6 lens captures clear night vision—perfect for package monitoring or checking visitors. Unlocking takes a blink thanks to its slim, responsive fingerprint film, and auto-lock ensures you never leave the door open. For renters or homeowners wanting complete door control in one device, this is a no-compromise solution.

In real-world use, the E330 delivers on both security and convenience. The three-in-one design eliminates the need for separate doorbell and lock installations, and built-in Wi-Fi enables remote viewing and unlocking from anywhere. Push notifications with thumbnail previews keep you informed, though they require brief cloud caching. The 10,000 mAh battery powers all features, but camera use will drain it faster than lock-only models—manage expectations on longevity.

Compared to the C220 or E31, the E330 offers integrated surveillance, making it ideal for users who want full situational awareness without extra hardware. While the S3 Max has higher storage and a rear screen, the E330 matches its core camera-lock functionality at a more accessible point. It’s the best pick for those who want camera, doorbell, and lock in one, delivering maximum functionality without monthly fees.
