8 Best Smart Locks for French Doors 2025

Effortless access meets endurance in the eufy Security Smart Lock C220, where fingerprint recognition and built-in Wi-Fi converge to redefine front door convenience. This deadbolt shines with its 8-month battery life, drastically reducing the anxiety of sudden power failure—a common pain point for smart lock users. The self-learning AI behind the fingerprint sensor adapts with every use, improving accuracy over time, while six unlock methods—including voice via Alexa and Google Assistant—ensure no one gets locked out. For French doors with standard deadbolts, this lock delivers reliable, keyless entry without demanding constant maintenance.

In real-world testing, the C220 proved remarkably responsive, unlocking in under 1.5 seconds with a clean fingerprint scan, even in chilly mornings down to -22℉. The IP53 waterproof rating held up against light rain and humidity, making it suitable for exposed entries. However, the lack of auto-lock by default means users must manually trigger it unless configured through the app, which could be a security gap for forgetful households. While it integrates smoothly with other eufy devices like doorbells, no physical handle limits its compatibility with French doors that require lever-based operation.

Positioned between budget models and high-end video locks, the C220 outlasts most competitors on battery while offering stronger ecosystem integration than basic keypads. It’s ideal for users who prioritize low maintenance and app-based access over all-in-one features like cameras. Compared to the TMEZON fingerprint knob, the C220 offers superior durability and smarter connectivity, though it lacks a built-in handle—making it better suited for standard front doors than dual-handle French doors.

Budget-smart doesn’t mean basic—the TMEZON Smart Door Lock brings five unlock methods and TUYA app control to the entry-level market without sacrificing core functionality. With a 0.2-second fingerprint scan and support for 50+ fingerprints and 100 IC cards, this knob-style lock is a game-changer for shared spaces like rentals or offices. The auto-lock feature, kicking in 5 seconds after closure, tackles the “did I lock the door?” dilemma head-on, while the anti-lock function adds privacy control from the inside—perfect for bedrooms or home offices within French door setups.

During testing, the fingerprint sensor delivered blazing-fast access, outpacing even pricier models in consistent recognition—provided the user wakes the lock first with a touch. The TUYA app, though Bluetooth-only, allowed seamless user management and log tracking from within the home. However, the lack of Wi-Fi means no remote access, limiting its use for vacation homes or frequent travelers. It performed reliably in temperatures between -22℉ and 158℉, but the IP rating isn’t specified, raising concerns for outdoor exposure. For French doors with standard prep, it installs in minutes—yet the plastic-heavy build feels less robust in high-traffic areas.

When stacked against the eufy C220, the TMEZON trades remote control and ecosystem depth for a fraction of the cost and a built-in handle, making it a smarter pick for interior French doors or secondary entries. It’s best for renters or homeowners seeking affordable, keyless convenience without subscription fees or complex setup. While it doesn’t offer the polish of premium brands, it delivers exceptional value for its price, especially where Wi-Fi isn’t a must-have.

Simplicity perfected—the eufy Security Smart Lock C30 is engineered for users who want smart access without the headache. With built-in Wi-Fi and no bridge required, it offers true remote control via the eufy Security app, making it ideal for checking lock status or granting access while away. The physical keypad, backed by durable buttons (not touch-sensitive), ensures reliable use in rain, snow, or low light—a standout for French doors exposed to the elements. Auto-lock scheduling adds peace of mind, and Alexa/Google voice support enhances hands-free convenience.

In real-world use, the C30 proved incredibly user-friendly, with setup taking under 15 minutes and app navigation feeling intuitive. The 5-month battery life is solid, though shorter than the C220, and the low-battery alerts give ample warning. It handled repeated use across varying temperatures (-22℉ to 158℉) with no hiccups, and the IPX3 waterproofing fared well in light storms. However, the fingerprint sensor is absent, limiting unlock options to keypad, app, voice, or key—potentially frustrating for users seeking touchless access. Like other eufy deadbolts, it doesn’t include a handle, restricting compatibility with French doors needing dual levers.

Compared to the Veise VE017-H, the C30 offers better app integration and remote control, but lacks fingerprint access and a sleek touchscreen. It’s best for users who value reliability and remote monitoring over biometrics, especially on French doors already equipped with handles. While it doesn’t have the bells and whistles of higher-end models, its no-nonsense design and solid connectivity make it a top pick for easy, secure upgrades.

Security redefined—the eufy Video Smart Lock E330 is a 3-in-1 powerhouse that combines a fingerprint deadbolt, 2K HD camera, and video doorbell into one sleek unit. For French doors serving as primary entrances, this lock eliminates the need for separate devices, offering real-time monitoring and instant alerts when someone approaches. The fingerprint unlocks in a blink, and the 10,000 mAh rechargeable battery powers all features for weeks, removing the chore of battery replacements. With thumbnail push notifications, you see who’s at the door before unlocking—ideal for managing deliveries or guests remotely.

Field testing revealed excellent camera clarity, even at night thanks to the f/1.6 lens and infrared night vision. The two-way audio worked seamlessly, allowing clear communication through the eufy app. However, the auto-lock feature must be manually enabled, and the camera’s field of view may not fully cover wide French door entries, depending on mounting height. While the built-in Wi-Fi enables full remote access, the device is bulkier than standard deadbolts, which could affect aesthetics or fit on thinner doors. It thrives in setups where visual verification is critical, but may overwhelm users preferring minimalist hardware.

Against the Philips Smart Lock, the E330 offers superior standalone functionality—no gateway needed—and richer visual feedback. It’s best for tech-savvy homeowners who want all-in-one security and remote oversight without extra devices. While pricier, its integration of camera, doorbell, and lock delivers unmatched value for those prioritizing total entry control.

Elegant control at your fingertips—the Veise VE017-H blends retro aesthetics with modern app-driven management, making it a top contender for French doors where style and function intersect. With five unlock methods, including fingerprint, app, fobs, and keys, it offers unmatched flexibility for families, guests, or rental management. The KK Home app stands out with voice announcements in three languages and the ability to generate temporary and cyclical codes, perfect for Airbnb hosts or visiting relatives. AES-128 encryption ensures biometric data stays private, while the IP55 rating promises resilience in rain or snow.

In practice, the fingerprint sensor was highly accurate, locking and unlocking smoothly in under a second. The auto-lock feature engaged reliably, and the emergency power port provided peace of mind during battery drain. Installation was truly tool-free and took under 15 minutes on a standard French door. However, full remote access requires the G1 gateway (sold separately), limiting out-of-home control unless you invest more. While the matte black finish looked premium, the lack of built-in Wi-Fi means Bluetooth-only proximity control without the hub—hindering true remote usability.

Compared to the Philips Smart Lock, the VE017-H offers better multilingual support and stronger security encryption, but falls short in seamless remote access without extra hardware. It’s ideal for users who manage guest access frequently and want a sleek, standalone smart lock with excellent local control. For French doors with lever handles, it’s a stylish, secure upgrade—just be prepared to buy the gateway for full smart home integration.

Engineered for sliding French doors, this slim-frame smart lock is a rare solution for patio and glass entries that resist standard deadbolts. With five access methods, including fingerprint, app, RFID cards, and keypad, it delivers full keyless convenience where traditional locks fail. The IP65 weatherproof rating ensures it withstands rain, snow, and extreme heat (-12°F to 148°F), while surviving over 16,000 lock cycles—a testament to its durability. For vacation homes or backyard French doors, the 8+ month battery life and emergency power bank support mean uninterrupted security, even during long absences.

Testing confirmed it installed smoothly on a 1.8” frame, securing a sliding glass French door without modification. The Bluetooth app allowed user management and access logs, though no Wi-Fi means no remote monitoring—a limitation for off-site control. The fingerprint sensor responded quickly, but lighting conditions occasionally affected recognition. Unlike round deadbolts, this low-profile design fits narrow stiles, making it one of the few true smart locks for sliding French doors. However, it’s not suitable for hinged doors, narrowing its use case.

Compared to the eufy E330, it lacks a camera or remote live view, but excels in niche compatibility. It’s the best choice for sliding or patio French doors where standard locks won’t fit. While not a whole-home solution, its specialized design and rugged build make it indispensable for specific installations.

Maximum access, maximum control—the Veise VE017-L stands out with six unlock methods, including M1 cards and app sharing, making it the most versatile option for French doors in high-traffic homes. The FPC fingerprint sensor boasts 99.99% accuracy, outperforming many rivals, and the anti-peep password feature lets you enter digits around your code to hide it from prying eyes. With up to 12 months of battery life, it outlasts most smart locks, and the -35°F to 160°F operating range ensures reliability in extreme climates—perfect for drafty French entries.

In real use, the app-based access management was intuitive, allowing granular control over temporary and recurring codes. The auto-lock function engaged consistently, and the satin nickel finish resisted fingerprints and scratches. Installation was a breeze with just a screwdriver. However, like other Veise models, full remote access requires the G1 gateway, limiting true smart home integration unless purchased separately. While Alexa and Google support work with the hub, standalone use feels incomplete without it.

Against the Philips Smart Lock, the VE017-L offers longer battery life and better security features, but similar handle-based design. It’s ideal for users who need multiple access types—like fobs for kids or staff—and want enterprise-level control at home. For French doors needing dual levers and flexible user management, it’s a top-tier choice.

The gold standard for French door upgrades, the Philips Smart Lock with Handles earns its Best Overall title by balancing design, security, and smart integration flawlessly. With two lever handles included, it’s perfect for replacing entire locksets on French doors, offering a cohesive, premium look. The fingerprint sensor delivers instant access, supporting up to 50 users, while unlimited one-time PINs make guest access effortless—ideal for hosts or busy households. When paired with the Philips Wi-Fi Gateway (sold separately), it unlocks remote control, voice commands, and detailed logs, transforming it into a true smart home centerpiece.

In testing, the Bluetooth unlock was seamless within range, and the auto-lock engaged reliably when the door was fully closed—though it lacks a door sensor to confirm closure, requiring user diligence. The 100 user PINs and timed codes were easy to manage via the app, and the build quality felt solid and tamper-resistant. However, the need for a separate gateway for full functionality adds cost and complexity, and voice control isn’t possible without it. For French doors in primary entrances, it offers the most complete package—just ensure your door thickness (1-3/8” to 1-3/4”) matches.

Compared to the eufy E330, the Philips lock lacks a built-in camera, but excels in handle integration and PIN flexibility. It’s best for users who want a full door upgrade with elegant hardware and robust access control. While not the cheapest, it delivers the most holistic experience for French door security.
