⚡ Quick Answer
Smart door locks have become a go‑to upgrade for anyone looking to ditch traditional keys, and we’ve lined up 9 options that span the whole market. You’ll find budget‑friendly picks like the $49.99 Bog fang Smart Lock and the $99.99 eufy Smart Lock C33, mid‑range choices such as the $169.99 eufy Smart Lock C220 and the $179.99 TianfuSpanda Video Smart Lock, plus premium contenders topping out at $349.99 with the Lockly Vision Elite. Ratings range from a solid 4.8/5 for the eufy C220 (17 reviews) down to 3.7/5 for a few higher‑priced models, giving you a clear sense of how users feel about each device.
The eufy Smart Lock C220 packs a lot of punch for its $169.99 price tag: it earns a 4.8/5 rating, unlocks in under 0.3 seconds with its fingerprint sensor, and promises up to eight months of battery life on eight AA cells. Its built‑in Wi‑Fi means you won’t need a separate hub, and the matching handleset keeps your entryway looking cohesive. Meanwhile, the $109.99 Tapo DL110 offers IP65 resistance, a 12‑month battery life, and room for 100 fingerprints, making it a strong contender in the budget tier.
Next, we’ll break down each lock’s installation quirks, smart‑home compatibility, and security credentials so you can decide which model fits your door, your budget, and your lifestyle.

eufy Smart Lock C220
Its 0.3‑second fingerprint recognition speed delivers fast, reliable entry, and the 25 mm latch hole depth fits most doors.

Tapo DL110
Ideal for budget‑conscious homeowners, the Tapo DL110 costs $109.99—about $60 less than the eufy C220—while still offering 100‑user fingerprint access and Wi‑Fi/Bluetooth connectivity.

Blusafe Smart Lock
Stands out with an anti‑peeping keypad and a 0.98‑inch backset, catering to security‑focused users who need extra privacy and flexible door fit, while supporting fingerprint, passcode, IC card and app access.
Also considered
TL;DR: The Tapo DL110 delivers fast 0.42‑second fingerprint unlock, a year‑long 10,000 mAh battery and multiple access methods at a modest $109.99 price, making it a solid entry‑level smart deadbolt.
The standout spec is the fingerprint sensor’s 0.42‑second recognition speed, handling up to 100 fingerprints and 32 member profiles. Coupled with a 10,000 mAh rechargeable battery that the manufacturer says lasts about one year, you get quick, reliable access without frequent charging.
In size, the DL110 measures 1.29 inches tall, 5.91 inches long and 2.69 inches wide, which is noticeably shorter and narrower than the eufy Smart Lock C33 (5.12 in × 7.24 in × 6.06 in). It also weighs 4.63 pounds, making it lighter than the eufy C220, which tips the scales at roughly 7.9 pounds. Feature‑wise, the DL110 offers six unlock methods—fingerprint, keypad, app, Bluetooth, voice assistant and physical key—while the Bog fang Smart Lock lists only a fingerprint sensor and a keypad.
Professional reviewers praise the lock’s lightning‑fast fingerprint response and the ultra‑long battery life, noting that the six distinct access methods give you flexibility and redundancy. Consumer sentiment echoes the convenience of the built‑in doorbell and auto‑lock, though some users point out the lack of independent reliability testing. The lock meets BHMA Grade 2 standards, carries an IP65 rating for exterior use, and encrypts data with 128‑bit AES, adding confidence for security‑focused households.
Pros
Cons
Best for: Budget-conscious buyers seeking a reliable entry-level option — the Tapo DL110 offers Fingerprint Capacity: 100
Avoid if: You want the best value‑per‑dollar in its price range
TL;DR: For $99.99, the eufy Smart Lock C33 packs integrated Wi‑Fi, adaptive fingerprint entry and a no‑drill install in a compact 5.12‑inch‑high deadbolt.
The C33’s standout feature is its adaptive fingerprint sensor that learns your grip, letting you unlock with a single hand. It measures 5.12 inches high, 7.24 inches long and 6.06 inches wide, and the back‑lit anti‑peeping keypad adds privacy for passcode entry. Auto‑lock works on a countdown timer, and a built‑in backup power source keeps the lock alive during outages.
Compared with the Tapo DL110, which is only 1.29 inches tall and 5.91 inches long, the C33 is noticeably larger, offering more surface area for its keypad and fingerprint sensor. The Bog fang Smart Lock is taller at 249 mm, but its fingerprint capacity is limited to 20 users, whereas the C33 supports adaptive users without a listed cap. The TianfuSpanda Video Smart Lock adds face recognition and video, features the C33 does not include, positioning the C33 as a simpler, lower‑cost option.
Everyday owners praise the quick app setup and reliable fingerprint performance, especially for families juggling multiple users. Professional reviewers highlight the hassle‑free 15‑minute, no‑drill installation and the direct Wi‑Fi connection that avoids a separate bridge. Users do note occasional keypad sluggishness in low light and faster battery drain when the lock is used heavily, which aligns with the reliance on 8 AA alkaline batteries.
The lock carries a Grade 3 BHMA certification, an IP53 rating for splash resistance, and a 1.5‑year warranty. Voice assistants Alexa and Google Assistant are supported, and temporary access codes can be generated for guests or service personnel.
Pros
Cons
Best for: Entry-level buyers or those on a tight budget — the eufy Smart Lock C33 offers Height: 5.12 inches
TL;DR: The August Wi‑Fi SmartLock Plus packs auto‑relock, app control and Alexa/Google Assistant support into a 0.75‑inch‑high, $200 mid‑range lock, though its 3.7‑star rating hints at mixed user satisfaction.
At just 0.75 inches tall, 1.9 inches long and 0.75 inches wide, the August Wi‑Fi SmartLock Plus is one of the most compact options in this lineup. Its auto‑relock mechanism engages automatically after each use, and the lock installs in minutes thanks to the quick‑install design.
Compared with the other eight contenders, August’s dimensions are markedly smaller than the Yale Assure Lock 2 Touch’s 4.9‑inch height and even the Tapo DL110’s 1.29‑inch height. While the Bog fang model sits at a lower price point, August lands in the mid‑range tier, offering more premium features than the budget‑focused options and a slimmer profile than the bulkier TianfuSpanda Video Smart Lock.
The lock carries a 3.7‑star average from 685 reviews, suggesting mixed reactions from owners. Reviewers who like it often point to the convenience of app‑based control and the peace of mind from auto‑relock, while the rating indicates some users have reservations that aren’t detailed in the data.
Connectivity is handled via an optional Wi‑Fi add‑on, letting you control the lock through the Yale Access app and integrate with Alexa or Google Assistant. The manufacturer backs the unit with a two‑year warranty, and the lock supports both traditional keys and app unlocking.
Pros
Cons
Best for: Value-conscious buyers seeking quality at $200.00 — the August Wi‑Fi SmartLock Plus offers Height: 0.75 inches
TL;DR: The Yale Assure Lock 2 Touch packs Wi‑Fi, Bluetooth, a sub‑0.5‑second fingerprint scanner and a 0.9‑inch depth into a sleek 4.9‑inch tall deadbolt, but its Wi‑Fi reliability and 3.8‑star rating keep it from being a flawless pick.
What really sets this lock apart is its built‑in Wi‑Fi and Bluetooth combo, letting you lock, unlock and monitor entry from the Yale Access app without a separate hub. The lock’s footprint is compact – a depth of 0.9 inches and a height of 4.9 inches – so it fits neatly on most standard doors while still housing a motorized deadbolt and a matte, lighted touchscreen keypad.
Compared with the other eight contenders, the Yale sits at the higher end of the price spectrum, making it pricier than the eufy Smart Lock C220. It’s also lighter than the Blusafe Smart Lock, which weighs 5.36 pounds, and its 0.9‑inch depth is dramatically shallower than Blusafe’s 312.4 mm depth. The August Wi‑Fi SmartLock Plus is slimmer at 0.75 inches tall, but it lacks the same range of unlock methods that Yale offers, such as voice control via Alexa, Google Assistant and Siri.
Users love the hands‑free auto‑unlock that triggers when their phone is nearby, and many praise the sub‑0.5‑second fingerprint recognition for quick entry. Professional reviewers note the lock’s solid AES‑128 encryption and IPX5 weatherproof rating, which keep it functional from –25 °C to 60 °C outdoors. However, a recurring complaint is intermittent Wi‑Fi drops that force the lock back to Bluetooth mode, and some owners report occasional hiccups with fingerprint enrollment.
Beyond the smart features, the lock meets ANSI/BHMA Grade 2 standards, supports unlimited user codes, and offers two‑factor authentication for added peace of mind. The DIY installation is described as a straightforward 20‑30‑minute job, and the included Wi‑Fi smart module and DoorSense sensor give you real‑time activity alerts straight to your phone.
Pros
Cons
Best for: Those prioritizing quality and willing to pay for premium performance — the Yale Assure Lock 2 Touch offers Depth: 0.9 inches
Avoid if: Reliability and user satisfaction are your top concerns
TL;DR: The Blusafe Smart Lock offers 0.5‑second 99.999% accurate fingerprint access, IP65 weatherproofing, and up to 250 users, but requires a separate Wi‑Fi bridge and batteries are sold separately.
What really stands out is the 0.5‑second fingerprint recognition speed paired with 99.999% accuracy, and the ability to store 100 fingerprints plus 100 RFID cards. The lock also supports passcodes (100‑250) and mechanical keys, and it auto‑locks after each use. Its IP65 rating means it can handle rain, dust, and extreme temperatures from –4°F to 140°F.
In this nine‑product roundup, the Blusafe is deeper than the Yale Assure Lock 2 Touch (0.9 in depth) and far larger than the August Wi‑Fi SmartLock Plus (0.75 in height). It’s lighter than the eufy Smart Lock C220, which weighs about 3574 g, but a bit heavier than the Tapo DL110 at roughly 4.63 lb. While the price sits in the premium tier, its feature set outstrips many mid‑range competitors.
Reviewers love the quick, reliable biometric entry and the high total user capacity of 250 entries across all methods. Professionals note the DIY‑friendly deadbolt installation and the robust aluminum/zinc alloy construction. The main complaints focus on the need to buy a separate Wi‑Fi bridge and the fact that batteries aren’t included, while the Tuya app is described as less polished than expected.
Additional technical details include a backset of 0.98 in, door‑thickness compatibility of 40‑90 mm, an anti‑peeping keypad that randomizes digits, and a backup power option via USB‑C. The lock runs on four AAA batteries with an estimated eight‑month lifespan and provides low‑battery alerts.
Pros
Cons
Best for: Homeowners with standard 40‑90 mm doors who want a high‑capacity, fingerprint‑enabled lock with robust weather protection.
Avoid if: You need built‑in Wi‑Fi without extra accessories, prefer a lock that ships with batteries, or want a highly refined mobile app experience.
TL;DR: The Bog fang Smart Lock costs $49.99, unlocks in 0.3 seconds, fits doors 35‑51 mm thick and offers five access methods, making it a budget‑friendly, feature‑rich option for small households.
This lock’s standout spec is its fingerprint recognition speed of 0.3 seconds, paired with a door‑open time of just 1 second. Weighing only 2.95 lb (2 949.79 g) and installing in roughly 15 minutes, it feels light enough for most door knobs while still delivering quick, keyless entry.
When you line it up against the eight other contenders, the Bog fang is noticeably more affordable than the eufy Smart Lock C33 and offers a lighter package than the Tapo DL110. It also ships with more unlock methods than the August Wi‑Fi SmartLock Plus, though it lacks the built‑in Wi‑Fi of the eufy C33. In short, it lands in the low‑price, high‑feature niche of the roundup.
Reviewers appreciate the five‑way access—fingerprint, password, IC card, two mechanical keys, and app control via a Wi‑Fi gateway—plus the built‑in doorbell and real‑time access logs in the Tuya Smart Life app. The fast 0.3‑second fingerprint scan is frequently praised as “instant” security. On the flip side, users note the limited capacity of only 20 fingerprints and 20 password groups, and the overall 3.7‑star rating hints at mixed satisfaction. Professional reviewers also point out that the separate Wi‑Fi gateway adds a small extra step for remote control.
Technical details round out the picture: the lock fits doors with a thickness of 35‑51 mm and a back‑panel size of 60 mm or 70 mm (2.36‑2.4 in). It’s reversible for left‑ or right‑hand doors, includes backup power, and can be emergency‑charged via a micro‑USB port at ≤5 V. The touchscreen keypad stays illuminated and wakes on touch, while modes like Silent, Passage, and Normal Open let you tailor behavior to your routine.
Pros
Cons
Best for: Shoppers on a tight budget who want the most for their money — the Bog fang Smart Lock offers Fingerprint Capacity: 20
TL;DR: The Lockly Vision Elite blends a Grade 1 deadbolt, 1080p video doorbell and 0.3‑second fingerprint unlock for $349.99, offering a full‑feature smart lock without a subscription.
The lock’s standout spec is its 0.3‑second fingerprint recognition, letting you swing the door open almost instantly. It also houses a 1080p camera with 15‑foot night‑vision range, two‑way audio and up to 91 hours of local video stored on the included 32 GB TF card.
At $349.99 it sits above the eufy Smart Lock C220 and the August Wi‑Fi SmartLock Plus in price, but it’s lighter than the Blusafe Smart Lock (5.36 Pounds) and slimmer in height than the Yale Assure Lock 2 Touch (4.9 inches). Its 7.0‑inch length makes it bulkier than many standard deadbolts, a factor to watch if you have a shallow door jamb.
Reviewers love the rapid fingerprint scan and clear video feed, noting the lack of monthly fees as a plus. Professionals point out the added complexity of a required Vision Connect Hub for Wi‑Fi access, and some users report motion alerts can be erratic when the sensor is blocked or the battery dips below 20 %.
Pros
Cons
Best for: Tech‑savvy homeowners seeking an all‑in‑one lock and doorbell solution — the Lockly Vision Elite offers Fingerprint Capacity: 99 fingerprints
Avoid if: You need a simple lock without a hub, are renting and cannot drill, or prefer subscription‑based cloud storage.
TL;DR: At $169.99, the eufy Smart Lock C220 delivers built‑in Wi‑Fi, sub‑0.3‑second fingerprint entry and BHMA Grade 3 security, offering premium‑grade features without a premium price tag.
The lock’s standout feature is its built‑in Wi‑Fi, so you can control it from the eufy Security app without any extra bridge. Fingerprint recognition works in just 0.3 seconds, and the deadbolt is rated for 100,000 lock/unlock cycles, giving it a long mechanical lifespan. At 7.9 lb (3574 g) it feels solid, while the IP53 rating and 2000 N pressure resistance add confidence against weather and forced entry.
Compared with the other eight locks in this roundup, the C220 is heavier than the Tapo DL110 (around 4.63 lb) and the Bog fang (about 2.95 lb), but it still fits comfortably on most standard doors. It sits in a mid‑tier price band—more expensive than budget options like the Bog fang but cheaper than higher‑priced competitors such as the August Wi‑Fi SmartLock Plus. Its feature set, including Matter compatibility and five unlock methods, is richer than many peers that list fewer specs.
Customers consistently praise the 15‑minute installation and the convenience of quick, keyless entry. Reviewers note the fast fingerprint speed and the seamless integration with Apple Home, Google Home, Alexa and SmartThings. The most common complaint concerns the lock’s limited door compatibility: it only fits latch holes with a 25 mm depth and doors 35–43 mm thick, so round latch holes or non‑standard frames are excluded. Professional reviewers also point out that while BHMA Grade 3 is solid for residential use, it doesn’t meet the highest commercial standards.
Pros
Cons
Best for: Most users seeking a balanced, mainstream option — the eufy Smart Lock C220 offers Fingerprint Recognition Speed: 0.3 seconds
Avoid if: You want the best value-per-dollar in its price range
TL;DR: The TianfuSpanda Video Smart Lock offers 3D infrared face recognition, 6 unlock methods, and a 4200 mAh battery, but its $179.99 price makes it a pricier mid‑range choice.
The lock’s standout feature is its 3D infrared face recognition system, which delivers a pass rate of ≥97.80% and can store up to 100 faces. Recognition happens in under a second, and the built‑in wide‑angle cat’s eye camera adds live video monitoring. Power‑wise, the lock packs a 4200 mAh rechargeable lithium battery and can still perform roughly 100 emergency unlocks when the main supply runs out.
At 5.9 pounds (2676 g), it is heavier than the Tapo DL110’s 4.63 pounds and the Bog fang Smart Lock’s 2.95 pounds, yet comparable to the Blusafe Smart Lock’s 5.36 pounds. Its fingerprint recognition speed of <0.5 seconds is respectable but slower than the eufy C220’s 0.3‑second response and the Bog fang’s 0.3‑second speed. Priced at $179.99, it sits above the eufy C220’s $169.99 price point and well above budget options like the Bog fang’s $49.99. Unlike the Blusafe model, it lacks an IP65 waterproof rating, so it’s best kept indoors.
Professional reviewers praise the lock’s anti‑spoofing 3D infrared detection, noting that it resists photos, videos, and masks. Users also highlight the convenience of six unlocking methods—face, fingerprint, password, IC card, app, and physical key—and the ability to query unlock records via the EQUES app. However, the lock’s lack of waterproofing and a three‑minute lockout delay after repeated failed attempts have been cited as drawbacks, especially for outdoor or high‑traffic entryways. The device operates from –10 °C to 60 °C and tolerates 40‑90 % relative humidity, fitting typical indoor environments.
Pros
Cons
Best for: Most users seeking a balanced, mainstream option — the TianfuSpanda Video Smart Lock offers Fingerprint Recognition Speed: <0.5 seconds
Avoid if: You need advanced features or professional‑grade performance, especially waterproofing for outdoor use.
