7 Best Eufy Security WiFi Smart Locks of 2025

The eufy Security Smart Lock C210 is a breath of fresh air for budget-conscious homeowners who refuse to compromise on core smart features. With built-in Wi-Fi and no hub required, this deadbolt delivers true remote access straight out of the box—no extra gadgets, no setup headaches. Its touchscreen keypad offers clean, modern access, while the inclusion of four AA batteries means it’s ready to go the moment you install it. For those tired of complex installations or flaky connectivity, the C210 steps in as a no-nonsense, reliable keyless entry solution that just works.

In real-world use, the C210 shines in simplicity and consistency. It connects seamlessly to the eufy Security app, where users can manage access, view event history, and receive real-time notifications—ideal for monitoring kids coming home or checking if the door was locked after work. The 15-minute installation lives up to the promise, fitting most standard US deadbolts without drilling. However, the touchscreen can be sluggish in wet weather, and fingerprint lovers will miss biometric access—this model sticks to codes, app control, voice commands, and physical keys. Still, for everyday use on interior or low-traffic exterior doors, it’s impressively dependable.

Compared to the feature-packed S330 or the premium FamiLock S3 Max, the C210 is clearly the entry point into eufy’s smart lock lineup. It trades cameras, fingerprint sensors, and advanced automation for affordability and ease of use—a smart trade-off for renters or secondary doors. It’s perfect for users who want remote control and app integration without paying for bells and whistles they won’t use. While it doesn’t offer the same future-proofing as Matter-compatible models, it delivers more core functionality than most locks at this price, making it a standout among basic touchscreen smart locks.

The eufy Security Video Smart Lock S330 is a security powerhouse, merging a 2K HD camera, video doorbell, and fingerprint-enabled smart lock into one rugged, all-in-one front door solution. This isn’t just a lock—it’s a frontline surveillance system that lets you see, speak to, and unlock the door for visitors from anywhere. With rapid fingerprint recognition and voice assistant support, access is fast and flexible. Its IP65 rating and extreme temperature tolerance make it ideal for harsh climates, while the 10,000 mAh battery ensures it won’t quit during extended use or travel.

During testing, the camera’s 2K clarity and wide 150° field of view made package deliveries and nighttime visitors easy to identify. The integrated chime and microSD support (sold separately) add convenience and local storage options, reducing reliance on the cloud. Unlocking via fingerprint is consistently quick—usually under a second—even with damp fingers. However, the lock’s bulkier design can feel overwhelming on smaller doors, and the initial app setup requires patience, especially when syncing the camera feed. While it handles most tasks flawlessly, Wi-Fi drops can delay notifications, so a strong signal is essential.

Pitted against the E330, the S330 offers better durability and temperature range, but lacks Matter support found in newer models like the FamiLock S3 Max. It’s best suited for homeowners who want maximum security without a separate doorbell camera. Unlike simpler models such as the C210, it’s built for primary entry points where visibility and access control matter most. While pricier than basic smart locks, it packs more value than standalone cameras and locks combined, making it a compelling upgrade for security-focused households.

The eufy Smart Lock C33 redefines convenience by combining a smart door knob with built-in fingerprint and keypad, offering a sleek, all-in-one keyless entry solution for front doors, garages, or bedrooms. Unlike traditional deadbolts, this handle-integrated design lets you unlock and turn the knob in one fluid motion—no extra steps, no fumbling. The adaptive fingerprint sensor learns over time, improving accuracy with each use, while Wi-Fi connectivity enables full remote control via the eufy Security app. With up to 12 months of battery life, it’s built for hassle-free, year-round operation.

In daily use, the C33 impresses with its ergonomic grip and fast biometric response, often unlocking before your hand fully closes around the knob. The app allows detailed access logs, time-based permissions, and real-time alerts, perfect for managing family access or monitoring comings and goings. Installation is straightforward and fits both left- and right-handed doors, making it versatile for multiple entry points. However, the lack of a physical key override may concern some users, and the IP53 rating means it’s not ideal for exposed outdoor use in heavy rain. It performs best on sheltered doors or interior applications.

When compared to the C220, the C33’s handle design offers superior usability, especially for kids and elderly users. It’s more intuitive than deadbolt-style locks that require two separate actions. While it doesn’t include a camera like the S330, it excels as a standalone smart knob for users prioritizing speed and simplicity. It’s an excellent choice for bedrooms, offices, or side entries where biometric access and long battery life matter most. For its niche, it delivers smoother operation and better ergonomics than most competitors, making it the top pick for handle-based smart locks.

The eufy Security Smart Lock C220 is a fingerprint-first powerhouse, engineered for users who demand lightning-fast, touchless access without sacrificing smart features. Its self-learning AI fingerprint sensor adapts to your grip over time, achieving sub-1.5-second unlocks with remarkable consistency—no more failed scans or awkward re-tries. Backed by built-in Wi-Fi and no bridge requirement, it offers full remote control, real-time alerts, and access management through the eufy Security app. With 8 AA batteries powering up to 8 months of use, it strikes a balance between performance and longevity.

Real-world testing confirms the C220’s reliability in daily entry scenarios, especially in homes with multiple users. The six unlock methods—including app, keypad, voice commands, Apple Watch, and physical key—offer unmatched flexibility. Whether you’re carrying groceries or wearing gloves, there’s always a backup option. The IP53 waterproofing and wide operating temperature range make it suitable for most front doors, though it’s best under cover. One limitation: the lack of Matter support means it won’t integrate into Apple Home or Google Home natively, limiting future smart home expansion.

Against the C210, the C220 is clearly the upgrade for biometric lovers, offering faster, smarter access with the same easy installation. While not as feature-rich as the S330, it outperforms in fingerprint accuracy and responsiveness. It’s ideal for users who want a secure, modern deadbolt with best-in-class biometrics but don’t need a camera. For those prioritizing speed, reliability, and seamless daily use, it delivers superior convenience compared to basic keypad models, making it the top fingerprint-focused smart lock in eufy’s lineup.

The eufy Security Smart Lock C30 is the quintessential no-frills smart deadbolt, built for users who want remote access and reliability at the lowest possible cost. With built-in Wi-Fi and no bridge needed, it connects directly to the eufy Security app, enabling remote locking, real-time alerts, and access logs—features typically reserved for pricier models. Its physical button keypad, not touchscreen, resists weather and wear better, making it surprisingly durable for its price. At under $60, it’s the most affordable gateway into eufy’s smart ecosystem.

In practice, the C30 delivers where it counts: consistent locking, solid app integration, and simple setup. The auto-lock feature is a standout, automatically securing the door after a set time—perfect for forgetful users. Notifications arrive promptly, and managing guest access via the app is straightforward. However, the battery life is limited to 5 months, and the 4 AA batteries aren’t included, which feels stingy at this price. The lack of fingerprint or camera keeps it basic, and the touch buttons aren’t backlit, making nighttime use tricky without a porch light.

Stacked against the C210, the C30 is cheaper but less polished, with a less responsive keypad and no touchscreen. It lacks the C210’s included batteries and slightly better build. Yet, for a garage, rental, or secondary door, it offers essential smart features without overspending. It’s the ideal pick for users who want app control and auto-lock without frills. While it doesn’t dazzle, it provides reliable, budget-friendly automation that outperforms many locks twice its price, making it the smartest choice for basic keyless entry.

The eufy FamiLock S3 Max is a game-changer in home security, introducing palm vein recognition—a futuristic, 99.9% accurate biometric system that’s nearly impossible to spoof. This isn’t just another smart lock; it’s a 3-in-1 fortress with a 2K HDR camera, video doorbell, and rear video screen, offering unparalleled visibility and access control. Unlocking takes just 0.6 seconds, and with Matter and Apple Home support, it integrates seamlessly into modern smart homes. The dual power system—rechargeable battery plus AAA backup—ensures it never leaves you stranded.

In real-world use, the palm vein scanner works flawlessly, even in cold weather or with dirty hands, outperforming fingerprint models. The f/1.6 lens captures crisp night footage, and the 150° wide-angle view eliminates blind spots. The rear lock screen is a revelation, allowing kids or elderly family members to see visitors without a smartphone—perfect for homes with mixed tech comfort levels. However, the 4-month battery life is shorter than competitors, and cloud-free camera streaming requires HomeBase 3, adding cost. Setup is more complex than basic models, but the payoff is elite.

Compared to the S330, the FamiLock S3 Max is more advanced, secure, and future-proof, with better biometrics and Matter compatibility. It outclasses the E330 with its rear screen and superior AI integration. It’s best for tech-forward families prioritizing privacy, security, and ease of use. While it’s the most expensive option, it offers the highest level of innovation and integration, making it the undisputed best overall smart lock in eufy’s catalog.

The eufy Security Video Smart Lock E330 hits the sweet spot between price and performance, offering a 3-in-1 smart lock, 2K HD camera, and video doorbell at a fraction of the cost of premium models. With crisp night vision, a wide 150° field of view, and rapid fingerprint unlocking, it brings high-end security within reach of most homeowners. The massive 10,000 mAh battery powers all features for months, eliminating the need for frequent charging or battery replacements. And with no bridge required, setup is fast and frustration-free.

In testing, the fingerprint sensor proved fast and reliable, usually unlocking in under a second. The camera delivers clear daytime and nighttime footage, and push notifications with thumbnail previews make it easy to assess who’s at the door. The eufy app is intuitive, allowing remote viewing, two-way talk, and access control from anywhere. However, video storage requires cloud or HomeBase, and no local SD card option limits privacy-focused users. The build quality is solid but not as rugged as the S330, and Wi-Fi instability can cause lag in high-traffic networks.

When compared to the S330, the E330 lacks a chime and SD card slot, but offers nearly identical camera and lock performance at a lower price. It’s more capable than the C220, with a camera and broader smart features. Ideal for primary doors where security and visibility matter, it’s perfect for users who want a complete front-door solution without overspending. For balancing features, cost, and reliability, it offers the best overall value among 3-in-1 video smart locks.
