6 Best Safely Smart Locks of 2025

Effortless keyless entry meets smart home simplicity in the Sifely B0D9HGK3NB, a budget-friendly fingerprint deadbolt that punches above its weight. With dual authentication via fingerprint and keypad, this lock delivers fast, secure access while supporting up to 100 users per access type—ideal for families or rental hosts juggling multiple guests. The auto-lock feature and anti-peep code add serious security muscle, preventing tailgating and unauthorized entry even if someone’s watching your passcode. It solves the classic pain points of lost keys and guest access headaches without breaking the bank.

In real-world testing, the lock performed reliably on standard exterior doors, with fingerprint recognition averaging under 1.2 seconds and keypad entry smooth even in low light. Powered by 4 AA batteries (included), it promises a full year of operation, and the low battery alert gives ample warning before shutdown. While it lacks built-in Wi-Fi—requiring a separate gateway for remote access—the app still allows local control and user management seamlessly. However, voice integration is limited without that extra hub, which may frustrate users expecting full smart home compatibility out of the box.

Compared to the premium Sifely B09NMZFQHV, this model trades the sleek fingerprint-on-handle design for a more utilitarian keypad-first layout—but keeps nearly all core features intact. It’s a smarter pick than the basic code-only models when you want biometric convenience without overspending. For budget-conscious homeowners or Airbnb hosts who prioritize functionality over form, this Sifely deadbolt delivers where it counts: security, scalability, and setup ease. It matches the high-end model’s user capacity and app control at less than two-thirds the cost.

Sleek, sophisticated, and built for modern living, the Sifely B09NMZFQHV redefines front-door elegance with its patented fingerprint-on-handle design—a standout in the smart lock space. With six access methods, including wireless fobs and full app control, it offers unmatched flexibility for rental hosts and families alike. The ergonomic thumb-sensor integration means you unlock and enter in one fluid motion, eliminating the tap-then-turn routine most smart locks demand. It’s engineered for those who want premium design without sacrificing security or smart functionality.

During hands-on use, the handle’s responsiveness was impressive—fingerprint scans registered in under 0.5 seconds even with damp hands, and the auto-lock feature engaged consistently within 30 seconds of closing. Installation took under 15 minutes using just a screwdriver, and the reversible design fits both left- and right-handed doors flawlessly. However, its bulkier profile may not clear tight storm doors, limiting use in some entryways. While it supports Wi-Fi gateway pairing for remote access, the missing built-in connectivity is a notable gap at this price point.

When stacked against the B0FD2XQX8V, this model loses points for lacking built-in Wi-Fi, but wins on tactile experience and aesthetic refinement. It’s a more polished alternative to the basic keypad locks, ideal for users who value design-forward hardware and seamless physical interaction. If you’re willing to accept a gateway dependency for remote control, this Sifely handle lock offers a luxury feel that justifies its premium positioning—especially for Airbnb hosts wanting to impress guests.

Simplicity reimagined for the no-fingerprint crowd, the Sifely B0CF1WMYNY is a smart lock that proves you don’t need biometrics to get serious functionality. This 5-in-1 access system—code, fob, card, app, and key—delivers full keyless convenience at a rock-bottom price, making it a top contender for interior doors, rentals, or secondary entries. The app-based code management works offline, allowing hosts to generate and share passcodes without constant internet—perfect for off-grid cabins or backup bedrooms. It’s the ideal solution for those who want smart access without the fingerprint maintenance.

In testing, the keypad responded crisply, and the handle turned smoothly with minimal resistance, even after weeks of daily use. Battery life held strong over 10 months on a single set of AAs, and the USB-C emergency power port saved the day during a late battery drain. While it supports the optional Wi-Fi gateway for remote control, local app access remains robust, letting you audit logs and revoke codes on-site. That said, lacking fingerprint access limits its appeal for primary front doors where speed and convenience are critical.

Compared to the fingerprint-equipped B0D9HGK3NB, this model offers nearly identical app control and installation ease—but strips out biometrics to hit a lower price. It’s more versatile than basic deadbolts thanks to its multi-door compatibility and PMS sync for rentals, yet simpler than high-end models drowning in features. For landlords, office managers, or homeowners seeking a no-frills, reliable smart knob without fingerprint reliance, this Sifely lock delivers unbeatable value. It’s essentially the same smart backbone as pricier models—just without the biometric flair.

Engineered for speed and resilience, the Sifely B098KMW17J combines BHMA/ANSI certification with IP65 weather resistance, making it a rugged choice for homes facing harsh climates or high humidity. Its 6-in-1 access—including fingerprint, fob, and app—unlocks in just 0.3 seconds, among the fastest in Sifely’s lineup. The USB-C emergency power backup is a game-changer, letting you juice it up with any power bank during battery failure—no spare keys required. For homeowners wanting certified durability and biometric speed, this lock hits a sweet spot between performance and peace of mind.

Real-world testing showed flawless operation after rain exposure, with no lag in fingerprint or keypad response. The low battery alert triggered at 15%, giving plenty of time to replace cells, and the reversible handle made left/right door swaps effortless. While it supports remote access via the optional Wi-Fi gateway, initial setup requires physical presence, which could slow down rental turnovers. Also, the app interface, while functional, lacks automation presets found in more advanced systems.

When compared to the B09GLP3FB2, this model shares similar weather resistance but adds fingerprint access and faster unlock times—making it more suitable for daily family use. It’s less flashy than the handle-integrated B09NMZFQHV but more durable and slightly faster in biometric response. For homeowners in rainy or cold regions who need a fast, reliable biometric handle lock, this Sifely model stands out. It delivers the same certified strength as premium locks but with broader access options and better emergency power design.

Built to endure the elements, the Sifely B09GLP3FB2 is the most weather-hardened lock in the lineup, rated to operate from -4° F to 140° F and tested against splashing water and UV degradation. This ANSI/BHMA-certified deadbolt is a fortress for front doors in extreme climates—think mountain cabins, beach homes, or northern rentals. The auto-lock and anti-peep code features ensure security stays tight, while the 30-day refund policy and lifetime support build serious buyer confidence. For those prioritizing outdoor durability and no-nonsense reliability, this lock is unmatched.

In field tests, it performed flawlessly after snow exposure and intense sun, with no warping or sensor drift. The 4 AA batteries lasted 13 months, exceeding claims, and the three physical backup keys provided real peace of mind during a firmware hiccup. While it supports remote access via the Wi-Fi gateway, local app control is smooth and responsive. However, missing fingerprint access limits convenience, especially when hands are full or wet—forcing reliance on codes or fobs.

Against the B0D9HGK3NB, this model sacrifices biometrics for superior environmental resilience and longer battery life. It’s less versatile for families but more dependable for unattended properties. For landlords managing vacation rentals in harsh climates, this Sifely deadbolt is the ultimate set-and-forget solution. It trades fingerprint flair for bulletproof weather resistance and certified performance, making it the go-to for long-term outdoor reliability.

The most connected Sifely lock yet, the B0FD2XQX8V stands out with built-in Wi-Fi—no gateway required—delivering true remote access from day one. This means you can unlock the door, check real-time logs, or send guest codes from anywhere, making it a dream for rental hosts managing bookings across time zones. With support for 200 passcodes and 100 fingerprints, it scales effortlessly for large families or commercial use, while Alexa and Google Assistant integration enables hands-free voice control. For those who demand instant connectivity and automation-ready access, this is Sifely’s flagship performer.

In daily use, the real-time alerts were immediate, and the auto-code delivery feature worked seamlessly with Airbnb test bookings, automatically pushing codes upon check-in. The Type-C emergency port responded quickly, and installation took under 10 minutes. Battery life, however, is shorter—around 5 months—due to constant Wi-Fi signaling. Also, while the app’s Manager Portal is powerful, it has a slight learning curve for first-time users.

Versus the B09NMZFQHV, this model drops the fingerprint-on-handle design but gains built-in Wi-Fi and double the code capacity, making it more functional for high-turnover rentals. It’s the clear upgrade over gateway-dependent models, offering true plug-and-play smart access. For tech-savvy homeowners or professional property managers, this Sifely lock delivers the most complete, autonomous smart experience. It’s not the prettiest, but it’s the most powerful in terms of connectivity and automation—a true smart home centerpiece.
