8 Best Waterproof Smart Locks of 2025

The eufy Security Smart Lock C220 bursts out of the gate with its self-learning AI fingerprint recognition, a standout feature that adapts and improves with every touch—no more fumbling at the door trying multiple angles. Backed by built-in Wi-Fi and 8-month battery life, it eliminates the need for a hub while ensuring consistent connectivity and long-term reliability. With IP53 waterproofing and operation in extreme temperatures down to -30°C, this lock handles rain, snow, and blistering heat like a champ, making it ideal for homeowners tired of flaky Bluetooth-only models.

In real-world testing, the C220 shines in daily use: unlocking in under 1.5 seconds via fingerprint, responding instantly to app commands, and delivering crisp notifications when someone accesses the door. The integration with the eufy Security app allows seamless access management and event history tracking—especially useful if you’re syncing with a eufy doorbell. However, the lack of auto-lock is a noticeable gap compared to competitors, requiring manual locking unless you use voice commands or the app. While the deadbolt feels solid, the Grade 3 certification means it’s built for residential durability rather than commercial-grade threats.

Positioned against Wi-Fi smart locks under $100, the C220 carves a niche with its AI-driven biometrics and ecosystem synergy for existing eufy users. It’s perfect for tech-savvy families or renters who want reliable, hub-free remote access without overspending. Compared to the Veise VE012W, it offers better fingerprint accuracy and longer battery life, though at a slightly higher price point and with less weather resistance. For those prioritizing smart learning and app control, this lock delivers smarter access with fewer retries—a quiet upgrade that just works.

The Philips Smart Lock strides into the market with trusted brand engineering and a robust auto-lock feature that silently secures your home within seconds of closing the door—ideal for forgetful users or busy households. Its IP54 waterproof rating and 2200N pressure resistance signal serious durability, while the physical keypad buttons (non-touchscreen) offer reliable input even with wet or gloved hands. With built-in Wi-Fi, remote access is seamless, and real-time alerts keep you informed whether you’re across town or on vacation.

During testing, the lock proved exceptionally consistent: auto-lock activated reliably after door closure, and the app responded quickly to remote unlock commands. The 100-password capacity with permanent, one-time, and timed options makes guest access easy—perfect for Airbnb hosts or families with frequent visitors. However, the 6-month battery life falls short compared to others in this list, and the lack of fingerprint support means biometric convenience is off the table. The physical key override works smoothly, but the overall design feels more utilitarian than premium.

When stacked against the ULTRALOQ U-Bolt Pro, the Philips lock trades high-end features like Grade 1 security and AI fingerprinting for dependable automation and strong customer support. It’s best suited for users who value brand reliability, simple operation, and hands-free auto-locking over flashy tech. While it doesn’t match the feature density of pricier models, it offers solid performance with fewer glitches, making it a trustworthy pick for first-time smart lock adopters who want peace of mind without complexity.

The Veise VE027-K isn’t just a smart lock—it’s a complete door handle upgrade that transforms your entryway with sleek aesthetics and full smart functionality. What sets it apart is its IP65 waterproof rating, the highest among handle-style smart locks here, meaning it shrugs off heavy rain, dust, and snow like a pro. With seven unlock methods, including fingerprint, app, keypad, IC card, and voice control, it offers unmatched flexibility—ideal for large families or shared homes where everyone has their preferred access style.

In real-world use, the auto-lock feature (customizable from 10–180 seconds) works flawlessly, and the app delivers instant alerts and access logs. The fingerprint scanner is fast and accurate, though slightly slower in cold weather. The handle design feels premium, and installation is truly DIY-friendly—no drilling, just a screwdriver. However, the battery life is limited to 240 days, which means more frequent changes than competitors, and the app (KK Home) can feel clunky compared to industry leaders like Tuya or eufy.

Compared to the iulock knob lock, the VE027-K brings Wi-Fi connectivity and fingerprint access, making it a major step up in smarts. But unlike the ULTRALOQ or eufy models, it lacks ANSI Grade 1 certification, so it’s better suited for low-risk residential use than high-security needs. It’s the go-to choice for those replacing their entire door hardware and wanting a modern, weatherproof smart entry system with maximum access options. For the price, it delivers more features than most full-handle locks, especially in wet climates.

The ULTRALOQ U-Bolt Pro earns its title as Best Overall with a Grade 1 ANSI certification—the gold standard in residential security—backed by IP65 weatherproofing and an 8-in-1 unlock system that includes AI fingerprint, anti-peep keypad, app, voice, eKey sharing, web portal, auto-unlock, and mechanical keys. This isn’t just a lock; it’s a smart home command center for your door, complete with a door position sensor that alerts you if the door is left ajar—a critical feature for safety-conscious users.

In real-world performance, the auto-unlock feature works like magic, detecting your phone’s proximity and unlocking the door as you approach—no fumbling for keys or phones. The fingerprint scanner is lightning-fast, and the app is intuitive, offering detailed access logs and remote sharing. It handles rain, snow, and extreme heat without a hitch, thanks to its rugged IP65 shell. However, the auto-unlock can occasionally lag in dense urban environments, and the 8-month battery life is solid but not class-leading. Still, the ANSI Grade 1 strength—35 times more durable than standard locks—makes it a fortress.

Compared to the eufy C220, the U-Bolt Pro offers superior security, auto-unlock, and smart home integration with SmartThings and IFTTT, though at nearly double the price. It’s the ideal pick for homeowners who want maximum protection, automation, and integration without sacrificing ease of use. For those investing in long-term home security, it delivers enterprise-grade durability with consumer-friendly smarts, outpacing most rivals in both performance and peace of mind.

The iulock keypad lock storms the budget arena with a stunning $40 price tag and IP65 waterproofing, making it the most affordable weatherproof smart lock on this list. Despite its low cost, it packs 50 user codes, auto-lock, silent mode, and even a Type-C emergency charging port—features often missing in competitors at this price. The metal construction feels surprisingly robust, and the backlit keypad ensures visibility at night, while the detachable silicone grip adds comfort and style to the handle.

In practice, the lock performs admirably for basic use: codes respond quickly, auto-lock engages reliably, and the 18-month battery life is exceptional for a budget model. It handles rain and sun without issue, making it great for back doors or garages. However, the lack of Wi-Fi or app control means no remote access or real-time alerts—limiting it to local-only operation. There’s also no fingerprint or voice support, so it’s purely code-and-key based. While the installation is simple, the app-free experience will frustrate users used to modern smart home integration.

Compared to the Veise VE012W, the iulock wins on battery life and price but loses badly on connectivity and remote management. It’s best for budget-conscious users who want a simple, durable, weatherproof keypad lock for a side door or rental unit. For under $40, it offers remarkable value and physical security, though it’s not a true “smart” lock in the connected sense. If you need basic digital access without Wi-Fi bloat, this is your no-frills champion.

The Veise VE012W punches far above its $49 price point with built-in Wi-Fi, fingerprint access, and auto-lock—a rare combo at this budget. It’s a true smart deadbolt that lets you manage access remotely, check lock status, and receive alerts via the KK Home app, all without a hub. The IP55 waterproof rating ensures resilience against rain and dust, while BHMA Grade 3 certification guarantees residential durability. For first-time smart lock buyers, it’s a gateway drug to home automation without the premium cost.

In real-world use, the fingerprint scanner is responsive, though occasional misreads occur in cold weather. The app is functional but not as polished as eufy or Tuya, and the auto-lock feature (10–180 seconds) works consistently. Battery life lasts up to 8 months, and low-battery alerts keep you ahead of power loss. However, the lack of Grade 1 security and no anti-peep keypad make it less ideal for high-risk areas. The deadbolt feels solid, but not indestructible.

Compared to the TEEHO TE012W, it’s nearly identical—same app, same specs—but the TEEHO offers 100 PIN codes vs. 50, giving it a slight edge. Still, the VE012W stands out as the best budget Wi-Fi smart lock with fingerprint access, perfect for renters or DIYers wanting remote control and biometrics without overspending. For under $50, it delivers more intelligence than expected, making it a smart starter lock that doesn’t skimp on essentials.

The TEEHO TE012W emerges as a strong alternative to the Veise VE012W, offering nearly identical specs but with 100 PIN codes and AES-128 encryption for enhanced security—making it a smarter pick for hosts or multi-user homes. With built-in 2.4GHz Wi-Fi, fingerprint access, and anti-peep PIN input, it blends privacy with convenience, allowing random digits before and after your real code to prevent shoulder surfing. The KK Home app is responsive, and Alexa/Google compatibility ensures smooth voice control.

Testing reveals solid performance: fingerprint unlock is fast, remote commands execute reliably, and the auto-lock feature works silently in the background. The IP55 rating handles typical outdoor exposure well, and 8-month battery life matches premium models. However, like its Veise cousin, the app lacks the polish of Tuya or eufy, and no Grade 1 certification limits its use in high-security scenarios. The deadbolt is sturdy, but not fortress-grade.

Compared to the SohoTeco ST380, it offers better PIN capacity and encryption, though the SohoTeco wins with Tuya app support and 3-year warranty. The TEEHO is ideal for budget buyers who want maximum user flexibility and privacy in a compact Wi-Fi deadbolt. For those seeking a secure, app-controlled lock under $60, it delivers better code management and smarter security than most rivals in its class.

The SohoTeco ST380 is a mid-range powerhouse that balances affordability, smart features, and strong support in a single, sleek package. With IP56 waterproofing, it outperforms IP55 rivals by offering better dust and moisture resistance—ideal for humid or rainy climates. The 8-month battery life is standard, but the power-saving mode extends it to 12 months, a rare and welcome feature. It supports 100 fingerprints and 50 passcodes, and the Smart Life/Tuya app ensures seamless integration with millions of smart home setups.

In real-world use, the fingerprint scanner is highly responsive, the anti-peep PIN function works flawlessly, and remote access is instantaneous. The auto-lock is customizable, and the emergency Type-C port saves the day when batteries die. What truly sets it apart is the 3-year warranty and lifetime support—a rarity in this category. However, the lack of Grade 1 certification means it’s not for high-risk areas, and 5GHz Wi-Fi isn’t supported, which could frustrate dual-band users.

Compared to the TEEHO TE012W, it offers better app ecosystem and longer warranty, though with fewer PIN codes. It’s the ideal pick for mid-budget buyers who want Tuya integration and long-term peace of mind. For those upgrading from mechanical locks, it delivers enterprise-level support with consumer pricing, making it one of the smartest balanced choices in the $50–$60 range.
