8 Best Eufy Smart Lock Deadbolts of 2025

Revolutionary palm vein recognition meets 24/7 surveillance in a single, powerhouse smart lock that redefines front door security. The FamiLock S3 Max doesn’t just unlock with a wave of your hand—it does so in 0.6 seconds with 99.9% accuracy, thanks to its forgery-proof vein pattern scanning. This isn’t just keyless entry; it’s biometric intelligence at the doorstep, eliminating the risk of copied fingerprints or lost keys. Paired with a 2K HDR camera and 150° wide-angle doorbell, it delivers round-the-clock monitoring, making it perfect for homes where elderly relatives or children need secure, hassle-free access.

In real-world use, the integrated 2K camera shines even in low light, capturing crisp, detailed footage of every visitor and package drop-off. The rear lock video screen is a game-changer—no smartphone needed to check who’s at the door, which is ideal for kids or seniors unfamiliar with apps. While the Wi-Fi connectivity is solid, streaming the camera via Matter isn’t supported (full features require the eufy App), and the lack of local storage options means you’re reliant on cloud backups unless using HomeBase 3. It handles ANSI/BHMA Grade 1 durability with ease, but the bulkier front assembly might not suit minimalist door designs.

Compared to the sleeker eufy C34, the S3 Max trades simplicity for comprehensive security integration—it’s not just a lock, it’s a smart home command center. While the C34 wins on affordability and Apple Home tight integration, the S3 Max dominates for families seeking all-in-one surveillance, access control, and privacy-first biometrics. It’s overkill for basic keyless entry but unbeatable for those prioritizing maximum security and home monitoring in one unit.

Sleek, seamless, and built for Apple lovers, the eufy Smart Lock C34 delivers effortless integration with Apple Home, making it the go-to choice for iPhone users who want one-tap unlocking and guest access control without extra hubs. With no bridge required, setup is a breeze, and its clean keypad design offers reliable access via app, voice, keypad, or physical key. The standout here is true plug-and-play compatibility with Apple’s ecosystem—unlock with your iPhone, automate routines with HomePod, and receive real-time notifications directly on your devices. It solves the classic smart lock pain point: complex setup and spotty connectivity.

During daily use, the 8-month battery life (powered by 8 AA batteries) proves impressively long-lasting, even with frequent unlocks. The Wi-Fi direct connection ensures remote access stays stable, and the event log and access management features are intuitive in the eufy app. It handles standard US and Canadian doors without modification, and the 15-minute installation lives up to its promise. However, it lacks advanced biometrics or a camera—so if you want real-time visuals or palm/fingerprint recognition, you’ll need to pair it with another device.

When stacked against the FamiLock E34, the C34 may lack premium biometric security, but it wins on simplicity, price, and Apple-centric functionality. It’s not the most feature-packed lock, but for iPhone households wanting reliable, no-fuss automation, it’s the smartest pick. It offers better value than pricier models when all you need is secure, remote-controlled keyless entry with native Apple Home support.

Elite biometric security meets all-day reliability in the FamiLock E34, a premium smart lock that prioritizes privacy and cutting-edge access control. Its palm vein recognition is lightning-fast at 0.6 seconds and nearly impossible to spoof, using internal vein patterns that can’t be replicated like fingerprints. Unlike cloud-dependent systems, your biometric data stays on-device, giving true privacy-first protection. Add built-in Wi-Fi and Matter support, and you’ve got a lock that’s both future-ready and deeply secure, ideal for users who won’t compromise on safety or convenience.

In real-world testing, the dual battery system stands out—its 10,000mAh main battery lasts up to 8 months, while the integrated backup battery eliminates lockouts during replacements. The auto-lock feature and voice control work flawlessly, and remote access via the eufy app is responsive from anywhere. It excels in harsh weather thanks to IP65 waterproofing, and the ANSI/BHMA Grade 1 rating confirms its durability. However, it lacks a camera or doorbell, so you won’t get visual verification of visitors—this is a pure access device, not a monitoring tool.

Compared to the S3 Max, the E34 drops the camera and rear screen but retains the same elite palm recognition at a lower price point. It’s a smarter choice than the C34 for users who want top-tier biometrics without surveillance features. If you’re after the most secure, private, and reliable keyless entry without video, the E34 delivers unmatched peace of mind with enterprise-grade protection in a residential package.

Fingerprint lovers, rejoice—the eufy Smart Lock C220 is a speed demon with a brain, using self-learning AI to adapt to your fingerprint over time for unlocking in under 1.5 seconds. It’s one of the few locks that actually improves with use, reducing false rejections and eliminating the frustration of repeated swipes. With six unlock methods—fingerprint, app, keypad, voice, Apple Watch, and key—it’s built for whole-family flexibility, making it ideal for homes with kids, guests, or aging parents. The BHMA Grade 3 durability and IP53 waterproofing ensure it withstands daily wear and weather.

In practice, the 8-month battery life holds up well, though the 8 AA batteries aren’t included, which feels like a missed opportunity at this price. The built-in Wi-Fi allows full remote control, and pairing it with eufy cameras enables automated routines like ‘unlock when I arrive’. The fingerprint sensor is responsive, but it can struggle with wet or cold fingers—something the palm vein models avoid entirely. It’s also bulkier than keypad-only models, and the lack of Matter support limits its smart home future-proofing.

Against the C210, the C220 offers clear advantages with fingerprint access and AI learning, justifying the slight price bump. While not as secure as palm vein models, it’s the best fingerprint-based lock in eufy’s lineup. For users who want fast, reliable biometrics without the premium price of palm recognition, the C220 strikes a smart balance between performance, convenience, and affordability.

Simple, reliable, and wallet-friendly, the eufy Smart Lock C210 is the perfect entry point into smart home security for users who want basic Wi-Fi control without complexity or cost. With five unlock methods—app, keypad, voice, Apple Watch, and key—it covers all the essentials for daily access and guest management. The built-in Wi-Fi means no hub, and the eufy app delivers smooth remote locking, real-time alerts, and access logs. It’s BHMA certified for 100,000+ cycles, proving it’s built to last, not just to sell.

In real use, the 4 AA batteries (included) power the lock for up to 5 months, which is solid but not class-leading. The touchscreen keypad is responsive, and the auto-lock feature adds peace of mind for forgetful users. Installation is truly 15 minutes and drill-free, fitting most standard US doors. However, it lacks advanced biometrics or a camera, and the lack of Matter support means it won’t integrate as deeply with future smart homes. It’s also only BHMA Grade 3, so it’s not as robust as Grade 1 commercial-grade models.

Compared to the C30, the C210 offers similar features but includes batteries and a slightly better app experience. It’s not as advanced as the C220 or C34, but for first-time smart lock users or rental properties, it’s hard to beat for simplicity and value. If you want a no-frills, dependable Wi-Fi lock that just works, the C210 is the smart starter choice.

Security, visibility, and convenience collide in the eufy Video Smart Lock S330, a 3-in-1 powerhouse that combines a fingerprint lock, 2K HD camera, and video doorbell into one rugged unit. It’s designed for users who want to see and secure their door without multiple devices, and it delivers with a crisp f/1.6 lens and 150° field of view that captures every visitor head-to-toe. The fingerprint sensor unlocks in under 1.5 seconds, and with five access methods, it keeps your home accessible even during outages. The included Chime enhances usability by alerting indoors to visitors.

In daily operation, the 10,000mAh battery powers all features for months, and the IP65 rating ensures weather resistance in rain or snow. The remote app lets you answer the door and unlock from anywhere, and push notifications with thumbnail previews give quick visual alerts. However, microSD card not included—you’ll need to buy one for local storage—and the camera stream can lag slightly on slower Wi-Fi. It’s also heavier than standard locks, which may affect some door alignments.

Versus the E330, the S330 offers similar specs but includes Chime and expandable storage, making it better for whole-home monitoring. It’s pricier than basic locks, but for users who want camera + lock + doorbell in one, it’s a space-saving, feature-rich solution. It doesn’t have palm vein security, but for balanced surveillance and access, the S330 delivers comprehensive home monitoring in a single, durable package.

Budget meets reliability in the eufy Smart Lock C30, the most affordable Wi-Fi deadbolt in eufy’s lineup that still delivers core smart features without compromise. With remote control via app, auto-lock, and voice access via Alexa or Google, it covers the essentials for secure, keyless entry. The physical buttons (not touchscreen) are a standout—more durable and weather-resistant than glass panels, ideal for high-traffic or outdoor use. At under $60, it’s an unbeatable value for users who want smart access without overspending.

In real-world testing, the 5-month battery life (4 AA batteries, not included) is decent, though you’ll pay extra upfront. The wrong-try protection deters brute-force attempts by locking after multiple failures—a small but smart security touch. Installation is quick and drill-free, and the eufy app is stable for notifications and access logs. However, it lacks fingerprint, camera, or Matter support, and the IPX3 waterproofing is minimal compared to higher-rated models.

Compared to the C210, the C30 is cheaper but lacks included batteries and Apple Watch support. It’s not for users wanting biometrics or video, but for rentals, secondary doors, or budget-first buyers, it’s the smartest basic lock available. If you need a no-frills, durable, app-controlled deadbolt at the lowest price, the C30 is the clear budget king.

Big security, small price—the eufy Video Smart Lock E330 is the best budget option with a built-in camera, packing 2K HD video, fingerprint access, and doorbell functionality into a sleek, easy-to-install package. It’s perfect for users who want visual verification and fast biometric unlocking without paying premium prices. The fingerprint sensor reacts in under 1.5 seconds, and the f/1.6 lens captures sharp night footage, making it ideal for package watchers and safety-conscious households. With five unlock methods, it’s flexible for family use.

The 10,000mAh battery powers everything—lock, camera, and doorbell—for months on a single charge, and remote access via the eufy app works smoothly. You’ll get push notifications with thumbnail previews (cloud-stored), so you can see who’s there instantly. Installation is 15 minutes, no drilling, and it fits most US/CA doors. However, microSD card not included, and no Matter support limits smart home expansion. The lack of Chime (unlike the S330) means indoor alerts rely on your phone.

Against the S330, the E330 drops Chime and local storage features but saves you money. It’s not as full-featured as the S3 Max, but for users wanting camera + fingerprint at a lower cost, it’s the most balanced budget video lock. If you need affordable, all-in-one door security with solid performance, the E330 delivers exceptional value without sacrificing core features.
