7 Best Eufy Smart Locks of 2025

The eufy Security Video Smart Lock E330 is a game-changer for front-door security, merging a fingerprint-powered smart deadbolt, 2K HD camera, and video doorbell into one sleek unit. With its f/1.6 aperture lens, the camera captures crisp footage even in near-total darkness, making it ideal for homes where porch lighting is minimal. What sets this model apart is its true 3-in-1 integration—no need to mount separate devices—delivering real-time alerts, remote unlocking, and two-way audio, all from your phone, solving the all-too-common problem of missing deliveries or unexpected visitors.

In real-world testing, the E330 shines on daily convenience and surveillance. The sub-1-second fingerprint unlock is consistently fast, even in cold weather, and the built-in Wi-Fi eliminates hub dependency, allowing seamless remote access from anywhere. The 10,000 mAh battery powers both lock and camera, lasting about 4–5 months under regular use, though heavy camera streaming can shorten that. While the auto-lock feature is reliable, the camera’s field of view (140°) is slightly narrower than premium competitors, and it struggles to capture full-height detail on taller visitors without slight angling.

Compared to the budget-focused C30, the E330 is in a different league of functionality, trading lower cost for integrated surveillance and biometrics. It’s a direct rival to the FamiLock S3 Max, but lacks palm vein tech and the rear viewing screen—making it best suited for tech-savvy users who want robust all-in-one security without top-tier pricing. It delivers more value than basic keypad locks, packing camera clarity and remote control that outclass most sub-$200 models.

The eufy Smart Lock C34 is a stealth powerhouse for smart home minimalists, offering seamless Apple Home integration and Matter support at a wallet-friendly price. It’s not flashy, but its clean compatibility with Apple Home, Alexa, Google, and SmartThings makes it a plug-and-play champion for users building a hub-based ecosystem. With no bridge required, setup takes minutes, and the app-based access management lets you grant temporary codes to guests or cleaners—perfect for urban dwellers or Airbnb hosts who hate physical key exchanges.

Performance-wise, the C34 delivers smooth, reliable operation across all unlock methods—app, keypad, voice, or key—with no noticeable lag. The 8-month battery life on AA cells is solid, and the low-battery alerts give ample warning, avoiding sudden failures. It handles standard US/CA doors with ease, installs in 15 minutes, and integrates cleanly into routines like “Unlock when I arrive home” via HomePod. However, it lacks a camera or fingerprint sensor, so you’re trading visibility for simplicity, and the keypad, while durable, isn’t backlit, making nighttime use a bit fiddly.

Against the pricier E31, the C34 offers nearly identical smart home support but with shorter battery life and no rechargeable power. It’s the ideal stepping stone for those entering the smart lock world without overspending—especially Apple users who want native Home app control without Matter headaches. While not as feature-rich as flagship models, it punches above its weight in ecosystem flexibility and ease of use, making it a smart buy for value-driven adopters.

The eufy Smart Lock C220 is a budget-savvy standout that brings fingerprint access and built-in Wi-Fi to the sub-$90 market—no small feat. Its self-learning AI fingerprint sensor adapts with use, delivering unlock times under 1.5 seconds and improving accuracy over time, which is rare at this price. With six unlock options, including Apple Watch and voice assistants, it’s built for families who want keyless convenience without complexity. The IP53 waterproofing and -22°F operating range mean it holds up in harsh weather, a must for exposed front doors.

In daily use, the C220 feels surprisingly robust, with responsive keypad input and solid motorized locking action. The 8-month AA battery life holds steady under normal use, and real-time app notifications keep you aware of entries and tamper attempts. It pairs effortlessly with eufy doorbells for unified routines, like unlocking when your camera detects a family member. That said, the fingerprint sensor can lag in wet conditions, and the lack of Matter support limits future-proofing, making it less ideal for evolving smart homes.

When stacked against the C34, the C220 trades Apple Home and Matter compatibility for fingerprint access and AI learning, making it better for biometric lovers on a budget. It doesn’t match the E31’s speed or battery, but for those who prioritize fingerprint entry over ecosystem depth, it’s a no-brainer upgrade from mechanical locks. It delivers premium features at a bargain, offering more biometric smarts than rivals under $100.

The eufy Smart Lock E31 is the undisputed king of Apple Home integration, built for iPhone-first households who demand speed, reliability, and Matter-ready automation. With unlock times under 0.3 seconds, it’s the fastest fingerprint lock in eufy’s lineup, thanks to a high-speed sensor that learns and adapts with every touch. Its 10,000 mAh rechargeable battery lasts up to 14 months, and the power-save mode extends life by another 30 days—a lifesaver during travel. Plus, emergency USB-C power access ensures you’re never locked out, even when the battery dies.

Real-world performance is consistently flawless—the lock integrates smoothly with HomePod, Alexa, and Google, allowing voice-unlock commands and geofencing automations without hiccups. The app delivers crisp event logs and instant notifications, and the auto-lock feature is fully customizable. It handles frequent use with ease, and the fingerprint sensor remains accurate in cold and dry conditions. However, like other eufy models, it lacks a camera, so you’ll need a separate doorbell for visual verification—making it best for users who already have a security camera setup.

Compared to the C34, the E31 offers faster unlock, longer battery, and rechargeable power, justifying its higher cost for Apple users. Against the C220, it’s faster, smarter, and more future-proof with Matter support. It’s perfect for tech-forward families who want lightning-fast, secure access and deep smart home integration without hub clutter. It delivers flagship performance with Apple-centric polish, outclassing budget models in speed, battery, and ecosystem depth.

The eufy Smart Lock C30 is the ultimate entry point into smart locking, offering built-in Wi-Fi and app control for under $60—making it the most affordable Wi-Fi deadbolt in eufy’s catalog. It’s simple by design: no fingerprint, no camera, just a durable keypad with physical buttons that resist wear and false touches. The auto-lock feature is a standout, securing your door after a set time, whether left open or closed—ideal for forgetful households. With real-time notifications and access logs, it gives peace of mind without complexity.

In testing, the C30 proves remarkably reliable, with instant app response and consistent keypad recognition. The 5-month battery life on 4 AA cells is the shortest in the lineup, requiring more frequent changes, but the low-battery alert is timely. It installs in 15 minutes with no drilling, works with eufy doorbells for unified routines, and supports voice unlock via Alexa and Google. However, the lack of backlighting on the keypad makes night entry awkward, and no Apple Home or Matter support limits its smart home reach.

Pitted against the C34, the C30 loses on battery life and ecosystem compatibility, but wins on price and rugged button design. It’s best for renters or secondary doors where basic remote access and auto-lock are the priorities. While it lacks biometrics and advanced integrations, it delivers core smart lock functions with bulletproof simplicity. For those who want no-frills, app-controlled security at the lowest cost, it’s hard to beat.

The eufy Smart Lock C33 is engineered for doors with handles, stepping away from traditional deadbolts to offer a fingerprint-enabled door knob that blends style, speed, and convenience. Its handle-grip fingerprint sensor unlocks the moment you touch it—no reaching for keypads or phones—making it perfect for kids, elderly users, or anyone with full hands. The 12-month battery life on a single charge is impressive, and the IP53 rating ensures weather resistance, so it performs reliably on garage or side doors exposed to the elements.

In real use, the seamless grip-to-unlock feels futuristic and intuitive, with the sensor adapting to your grip over time. Wi-Fi integration allows full remote control, including guest access and entry logs, and the app is responsive and easy to navigate. Installation is tool-free and takes under 15 minutes, with support for both left- and right-handed doors. However, the lack of Matter support limits automation depth, and fingerprint registration is less consistent for users with dry or cracked skin, requiring multiple re-scans.

Compared to the deadbolt-style C220, the C33 offers a more natural unlocking motion but sacrifices ANSI/BHMA Grade 1 durability for handle-specific design. It’s not a direct replacement for front door deadbolts, but excels in garages, basements, or backyard entrances where convenience trumps maximum security. For users wanting fingerprint ease on non-standard doors, it fills a unique niche with smart design and solid performance, outperforming keypad-only models in ergonomics and daily flow.

The eufy FamiLock S3 Max is the pinnacle of smart lock security, introducing palm vein recognition with 99.9% accuracy—a biometric breakthrough that’s nearly impossible to spoof. Unlocking in just 0.6 seconds, it uses infrared scanning to map your vein pattern, ensuring access only for authorized users, even in total darkness. Paired with a 2K HDR camera, 150° wide-angle lens, and integrated video doorbell, it delivers comprehensive front-door surveillance, eliminating blind spots and capturing crisp footage of every visitor.

In real-world testing, the palm recognition is flawless, working even with gloves off or wet hands—something fingerprint sensors struggle with. The rear video screen is a game-changer, allowing kids or seniors to see who’s at the door without a smartphone, promoting independent home safety. The dual power system—rechargeable battery plus AAA backup—ensures up to 5 months of operation, though camera-heavy use shortens that. While Matter support enables Apple Home and SmartThings integration, camera streaming isn’t available via Matter, requiring the eufy app for full functionality.

Against the E330, the S3 Max is faster, more secure, and more user-friendly, justifying its premium price with palm vein tech and rear screen. It’s the best overall choice for families wanting maximum security, ease of use, and future-proofing. While it’s overkill for basic needs, it excels in homes with children, elderly members, or high-security concerns, offering unmatched biometrics and visibility. It surpasses all other eufy locks in innovation and execution, setting a new benchmark for all-in-one door security.
