Best Wi‑Fi Smart Door Locks

TL;DR: The Ultraloq U‑Bolt Pro packs eight entry methods, 360° fingerprint sensor and built‑in 2.4 GHz Wi‑Fi into a robust ANSI Grade 1, IP65‑rated lock that weighs 3.3 lb and ships for $135.99.

The standout spec is its 8‑in‑1 access suite—fingerprint, keypad, smartphone app, auto‑unlock/lock, eKey sharing, Apple Watch, voice control and a mechanical key—combined with a 360° live capacitive fingerprint sensor that stores up to 100 fingerprints. The front panel measures just 2.95 × 2.95 × 1.22 inches, and the lock runs on four AA alkaline cells with a 6 V working voltage.

Compared with the other ten locks, the U‑Bolt Pro weighs more than the SimpliSafe model (0.95 lb), the August Wi‑Fi lock (0.399 lb), Kucacci (1.0 lb) and Yale (1.0 lb) units, but its weight gives it a solid feel. It also offers more entry methods than the SimpliSafe (PIN pad, key fob, app, voice, physical key) and August models, which rely on fewer options and often need an external bridge for Wi‑Fi. While its price point sits above many peers, the built‑in Wi‑Fi eliminates the extra hub cost that some competitors require.

Users consistently praise the rapid fingerprint unlock and the convenience of granting remote eKeys to guests. Professional reviewers note the ANSI Commercial Grade 1 certification and IP65 weather resistance as strong security and durability markers. On the downside, owners report occasional Wi‑Fi hiccups on congested 2.4 GHz networks and a reduced battery lifespan of 3–6 months when Wi‑Fi is active, versus longer intervals on Bluetooth‑only models. Some also mention fingerprint failures in wet or cold weather.

Additional technical details include 128‑bit AES encryption with a dynamic key, a door sensor that enables auto‑lock and status detection, and a micro‑USB backup power port for emergencies. The lock supports up to 50‑60 user codes (4‑8 digits) and integrates with Amazon Alexa, Google Assistant, SmartThings and IFTTT, giving you a flexible smart‑home ecosystem.

Best for: Tech‑savvy homeowners, renters, or property managers who want a hub‑free Wi‑Fi smart lock with biometric options.

Avoid if: You need a slim, low‑profile lock for tight door clearance or prefer longer battery intervals on Wi‑Fi.

TL;DR: The Veise VE017 offers a lightning‑fast 0.2‑second fingerprint sensor, 8‑in‑1 keyless access and built‑in Wi‑Fi for just $49.99, making it a solid budget smart lock.

An on‑device AI chip powers the 0.2‑second fingerprint recognition speed, the standout spec. Combined with Bluetooth and native Wi‑Fi, you can unlock the door via fingerprint, the Veise KK Home app, PIN code, two NFC cards or the included mechanical keys. The lock measures 68.6 mm deep, 76.2 mm high and 147.3 mm wide, and weighs 2.25 pounds (1021 g), fitting most standard deadbolts.

Compared with the other ten finalists, the VE017 is heavier than the Kucacci (1.0 pound) and the August Wi‑Fi Silver (0.40 pound) but lighter than the Ultraloq U‑Bolt Pro (2.8 pounds). Its fingerprint sensor is quicker than Kucacci’s 0.3‑second speed, and unlike Kucacci, Veise’s Wi‑Fi builds in rather than requiring a separate gateway. The lock also offers more access methods than the SimpliSafe Series 2 (which lists only PIN, app, key fob and voice) and the Yale Assure (which relies on a single‑cylinder deadbolt design). In the weight department, it sits between the lighter August 2nd Gen (0.87 pound) and the bulkier Ultraloq, giving it a solid middle ground for sturdy installation.

User feedback highlights the quick and straightforward installation, the convenience of near‑instant fingerprint entry, and the value‑for‑money feel at $49.99. Reviewers appreciate the included mechanical keys and NFC cards, as well as the IP55 rating that protects against dust and water. However, some note the scarcity of long‑term durability reports and wish for more independent durability testing. The manufacturer lists battery life as 12 months on four AA alkaline cells, and the lock includes a USB‑C emergency power port for backup.

Best for: Budget-conscious buyers seeking a reliable entry-level option

Avoid if: You need proven long‑term durability or prefer a lock with all voice‑assistant features built in without extra hardware

TL;DR: The August Smart Lock Pro + Connect Silver installs in under 10 minutes, weighs just 0.87 lb, offers a 15‑ft wireless range and DoorSense sensor, but needs a separate Wi‑Fi bridge for remote control.

This lock’s standout spec is its 15 ft (4572 mm) wireless range, which lets the August Connect bridge communicate reliably within a typical entryway. The DoorSense sensor adds open/closed detection, and the whole unit tips the scales at only 0.87 lb (395 g), making it a lightweight retrofit. Installation takes under 10 minutes with just a Phillips screwdriver, so you won’t need a professional.

Compared with other options in the roundup, the Pro + Connect is heavier than the ultra‑light August Smart Lock + Connect (0.175 lb) but noticeably lighter than the Schlage Encode Plus (around 3.0 pounds) and Level Lock+ (about 2.76 pounds). It also sits at a higher price point than the basic August model while still under $300, placing it in the premium tier of Wi‑Fi smart locks.

Users rave about the lock’s ability to keep existing keys and the simplicity of the retrofit, calling the app experience “effortless.” Professional reviewers highlight the deep integration with Z‑Wave, HomeKit, Alexa and Google Assistant, calling it a top‑selling automation choice. The main friction point is the need for the separate Connect bridge, which adds bulk and must stay within the 15‑ft range, and the manufacturer hasn't disclosed the battery lifespan.

Technically, the lock runs on Bluetooth v4.0, supports 2.4 GHz Wi‑Fi via the bridge, and includes a 908.42 MHz Z‑Wave radio for broader smart‑home ecosystems. Its physical profile is 3.4 in (86.4 mm) deep and high, 2.22 in (56.4 mm) wide, and it clears the door by 4.75 in (120.65 mm) when the latch is extended. Power comes from four AA batteries, with an optional AC adapter for the bridge.

Best for: Buyers willing to invest in a proven, high‑quality option.

Avoid if: You're on a tight budget, only need basic functionality, or have a multi‑cylinder deadbolt that can't accommodate a retrofit lock.

TL;DR: August Smart Lock + Connect adds Wi‑Fi remote access and voice control to August Bluetooth locks via a compact 2.8‑oz bridge, weighing just 0.175 lb, and earns a 4.4‑star rating from 2,700 reviewers.

The standout hardware piece is the August Connect Wi‑Fi Bridge, which measures just 38.9 mm deep, 59.9 mm high and wide, and tips the scales at 2.8 oz. Paired with the lock itself, which is only 0.175 lb, the whole system stays remarkably lightweight and unobtrusive on the door.

At 0.175 lb, this lock is lighter than the August Smart Lock 2nd Gen (0.87 lb), August Smart Lock Pro + Connect (0.87 lb), Yale Assure Lock 2 (1.0 lb), Schlage Encode Plus (3.0 lb), Ultraloq U‑Bolt Pro (2.8 lb) and SimpliSafe Series 2 (0.95 lb). While several peers need a separate hub, the Connect package bundles the bridge, giving you out‑of‑the‑box Wi‑Fi capability without an extra purchase.

Professional reviewers praise the bank‑grade AES‑128 encryption and TLS security, and they note the activity‑feed that logs each entry in real time. Everyday users love granting remote guest access and the smooth Alexa or Google Assistant voice commands. The downside, echoed by many, is that each lock requires its own bridge, which can add up for multi‑door homes, and the bridge only works on 2.4 GHz networks, so a congested Wi‑Fi environment may cause hiccups.

The lock pairs to the bridge over Bluetooth LE, then the bridge connects to a 2.4 GHz 802.11 b/g/n network that runs off a standard outlet. Power for the lock itself comes from four AA batteries, and the bridge draws no batteries. Editors also point out the quick 10‑minute installation, making the upgrade feel almost plug‑and‑play.

Best for: Existing August Bluetooth lock owners who want Wi‑Fi remote access without replacing the deadbolt, and renters looking for a simple upgrade.

Avoid if: You've got several doors that would need multiple bridges, rely on 5 GHz Wi‑Fi, or need a Windows‑only app.

TL;DR: The Kucacci Smart Door Lock Black offers seven entry methods, 0.3‑second fingerprint scans, and a DIY‑friendly 10‑minute install for $79.99, making it a solid budget Wi‑Fi‑ready choice.

The lock’s standout feature is its seven distinct access methods—fingerprint (recognition speed 0.3 seconds), PIN, smartphone app, key fob, mechanical key, Alexa voice (via Wi‑Fi gateway), and remote unlock. Auto‑unlock fires in just 1 second, and the unit carries an IP66 rating, so rain or snow won’t stop it from working.

At 1.0 pound, Kucacci sits in the middle of the pack: it’s heavier than the August Wi‑Fi Silver (about 0.4 pound) and SimpliSafe (0.95 pound), but lighter than Veise (over 2.2 pounds) and Ultraloq (2.8 pounds). Installation takes 10 minutes, matching SimpliSafe’s install time and faster than many bolt‑on solutions that require drilling. Wi‑Fi connectivity needs the optional KUCACCI gateway, a setup similar to August’s Connect Bridge but unlike SimpliSafe’s built‑in Wi‑Fi.

Reviewers love the flexibility: families and Airbnb hosts appreciate having fingerprint, PIN, and voice options all in one lock. Users note the voice‑alert for low battery and the 50‑unlock limit when power runs low as handy safety nets. AES256 encryption adds a layer of security that many budget‑tier locks don’t mention.

Technical extras include a door‑thickness compatibility of 35 mm – 55 mm, a reversible handle for left‑ or right‑hand doors, and an operating temperature range from –20 °F to 122 °F. If the power goes out, a USB power bank can serve as an emergency source.

Best for: Budget-conscious buyers seeking a reliable entry-level option

Avoid if: You need built‑in Wi‑Fi without purchasing an additional gateway

TL;DR: The Schlage Encode Plus Satin Nickel costs $292.79, offers built‑in Wi‑Fi, a 4.1‑star rating from 2,306 reviewers, and a Grade 1 security rating for premium residential use.

The lock’s exterior depth lists at 22.6 mm, giving it a relatively slim profile for a deadbolt, and it weighs 3.0 pounds (assembled weight 1360.8 g). Its fingerprint‑resistant touchscreen can store up to 100 user codes, and it includes a built‑in door‑movement alarm plus time‑delayed relocking.

At $292.79, it sits above the August Smart Lock Pro + Connect Silver ($268.98) but below the Level Lock+ Wi‑Fi ($345.99). Weighing 3.0 pounds, it outweighs the August models (0.87 lb and 0.175 lb) yet remains lighter than the Ultraloq U‑Bolt Pro (2.8 lb). The price point exceeds most of the eleven‑product lineup, which many reviewers note as a premium trade‑off.

Users consistently praise the native Wi‑Fi that removes the need for a separate bridge and the direct Apple Home Keys integration for tap‑to‑unlock on iPhone or Apple Watch. Professional reviewers highlight its ANSI/BHMA Grade 1 and Residential AAA certifications as commercial‑grade durability for a home door. However, several owners mention the exterior depth of 0.89 in (≈22.6 mm) can be too deep for a fully flush installation on thinner doors.

Best for: Those prioritizing quality and willing to pay for premium performance

Avoid if: You're shopping on a tight budget — it's priced at $292.79

TL;DR: For $119.99, the SimpliSafe Smart Lock Series 2 adds Wi‑Fi keyless entry and auto‑lock to a single‑cylinder deadbolt in about 10 minutes, but you’ll need a SimpliSafe Gen 3 system and a subscription for full remote features.

The lock’s most distinctive spec is its quick, drill‑free install: the package lists a 10‑minute installation time, and the unit measures just 32 mm in height, 195 mm in length, and 70 mm in width, weighing 0.95 pounds (431 g). Those dimensions let it sit neatly on most standard deadbolts while staying low‑profile enough to blend with the door.

Compared with the other ten contenders, the SimpliSafe unit is heavier than the August Smart Lock Wi‑Fi Silver at 0.399 lb, yet far lighter than the Ultraloq U‑Bolt Pro, which tips the scales at 2.8 pounds. Its 195 mm length exceeds the Ultraloq’s back‑panel length of 125 mm, while the 431 g weight is a shade lighter than the Kucacci Smart Door Lock’s 453.6 g. In the dimension department, it’s shorter than the Yale Assure Lock 2 Wi‑Fi’s 123.8 mm height, but its retrofit design matches the single‑cylinder compatibility of many peers.

Everyday owners repeatedly praise the lock’s straightforward setup and the auto‑lock that triggers when the SimpliSafe system arms; professional reviewers highlight it as a solid security boost. Users also appreciate the backlit PIN pad, key fob, and voice‑assistant support for Alexa and Google Assistant. However, the requirement of a SimpliSafe Gen 3 hub and a roughly $30‑per‑month subscription for full remote control is a common complaint, as is the need to replace four AA batteries and two CR2450 coin cells periodically.

The lock runs on 4 × AA and 2 × CR2450 batteries, offers storage for up to 20 unique 4‑digit PIN codes, and provides a low‑battery indicator via a blinking light, keypad message, and app notification. Auto‑lock can be set to engage on system arming, after a timer, or after multiple failed PIN attempts, giving you layered protection without extra hardware.

Best for: Existing SimpliSafe Gen 3 users who want a budget‑friendly retrofit lock with quick DIY installation.

Avoid if: You want the best value‑per‑dollar in its price range or need a lock that works across many smart‑home ecosystems without a subscription.

TL;DR: The Yale Assure Lock 2 Wi‑Fi retails for $198.94, offers built‑in 2.4 GHz Wi‑Fi, a 250‑code touchscreen keypad and auto‑lock, but its 3.8‑star rating and premium price may give pause.

The lock’s standout spec is its integrated 2.4 GHz Wi‑Fi, letting you lock or unlock from anywhere via the Yale Access app, Apple Home, Alexa or Google Assistant—no bridge required. Coupled with a 250‑code keypad and auto‑lock timer, it covers most remote‑access scenarios straight out of the box.

At 1.0 pound, the Yale is heavier than the August Smart Lock 2nd Gen Silver (0.87 pound) and the August Smart Lock Wi‑Fi Silver (0.40 pound), but lighter than the Ultraloq U‑Bolt Pro (2.8 pounds). Its depth of 22.2 mm is notably slimmer than August’s 86 mm depth, while its height of 123.8 mm sits between the shorter August Smart Lock Wi‑Fi Silver (69.85 mm) and the taller August Smart Lock Pro + Connect Silver (86.4 mm). In terms of dimensions, it’s comparable to the SimpliSafe Smart Lock Series 2 (width 70 mm) but narrower than the August Smart Lock 2nd Gen Silver (86 mm width).

Users consistently praise the convenience of the included four AA alkaline batteries and the reliable Alexa voice control. Families like the generous 250 user‑code capacity for sharing access. However, many report a tricky Wi‑Fi setup during the first install and note that the AA cells need periodic replacement. Professional reviewers also point out that you’ll need to buy a separate Z‑Wave or Zigbee module if you want those protocols, and the base model lacks a built‑in fingerprint sensor. It isn’t Matter‑compatible, which could limit future smart‑home expansion.

Technically, the lock carries an ANSI/BHMA Grade 2 rating, a door‑position sensor that reports open/closed status, and an audible alarm for added security. It operates from 14 °F up to 131 °F and stores safely down to –40 °F. The auto‑lock feature can be set to engage after a configurable delay, and a low‑battery indicator alerts you via the app and keypad.

Best for: Most users seeking a balanced, mainstream option

Avoid if: Reliability and user satisfaction are your top concerns, especially if you need built‑in biometric authentication or cannot install a retrofit deadbolt.

TL;DR: The August Smart Lock 2nd Gen Silver retrofits onto a single‑cylinder deadbolt for $199.99, weighs 0.87 lb, installs in under 10 minutes, and adds Bluetooth, voice control and auto‑lock features, but needs a separate Wi‑Fi bridge for remote access.

This lock’s most noticeable spec is its 86 mm depth, which sits on the interior side of the deadbolt while keeping the original key intact. At 0.87 lb (395 g) it’s lighter than the Yale Assure Lock 2 Wi‑Fi’s 1.0‑lb body, yet considerably deeper than Yale’s 22.2 mm depth. The retrofit design means you don’t have to replace the existing deadbolt, and the manufacturer lists the installation time as under 10 minutes.

Compared with the other ten entries, the August 2nd Gen is heavier than the August Smart Lock + Connect bridge‑only model, which weighs just 0.175 lb, but matches the weight of the August Smart Lock Pro + Connect (also 0.87 lb). It is slimmer than the Ultraloq U‑Bolt Pro’s bulkier form factor and lighter than SimpliSafe’s 0.95‑lb unit. Unlike several peers that ship with built‑in Wi‑Fi, this model requires an optional August Connect Bridge for remote control, adding an extra step and cost.

Users consistently praise the “no‑drill” retrofit that lets you keep your mechanical key as a backup, and they love the virtual guest keys that can be time‑limited. Activity tracking and DoorSense open/close alerts highlight as useful for peace of mind. Professional reviewers note HomeKit integration that enables Siri voice commands and the Auto‑Unlock feature that opens the door as you approach. The main complaints revolve around the need for a separate bridge and the $199.99 price point, which some consider high for a lock that still relies on four AAA alkaline batteries.

Best for: Apple HomeKit users, renters or homeowners who want a non‑destructive smart lock upgrade on a single‑cylinder deadbolt.

Avoid if: You need built‑in Wi‑Fi without an extra bridge, have a non‑single‑cylinder deadbolt, or are looking for a lower‑priced entry‑level lock.

TL;DR: The August Smart Lock Wi‑Fi Silver adds remote, voice‑controlled access to a single‑cylinder deadbolt for $114.99, weighs just 0.399 lb and installs in under 10 minutes, though its 3.9‑star rating signals mixed user experiences.

The August Smart Lock Wi‑Fi Silver adds remote, voice‑controlled access to a single‑cylinder deadbolt for $114.99, weighs just 0.399 lb and you can install it in under 10 minutes, though its 3.9‑star rating signals mixed user experiences.

What really sets this lock apart is the built‑in Wi‑Fi that works on both 2.4 GHz and 5 GHz bands, so you don’t need an extra bridge to reach it from anywhere. The unit is compact – only 46 mm deep, 2.75 in high and 2.8 in wide – and at 0.399 lb it feels almost weightless on the inside of your door. August also bundles Bluetooth 4.0 for local control and supports Alexa, Google Assistant and Siri, letting you lock or unlock with a simple voice command.

Compared with the other ten locks in this roundup, the August Wi‑Fi model is lighter than SimpliSafe’s 0.95‑pound lock and slimmer than the Ultraloq U‑Bolt Pro, whose back‑panel dimensions are noticeably larger. It also undercuts the Veise VE017’s heft of over 2 lb and is a bit lighter than the August 2nd Gen Silver at 0.87 lb. While Kucacci and Yale both tip the scales around 1.0 lb, the August Wi‑Fi’s 0.399 lb footprint makes it the most unobtrusive retrofit option for tight door jambs.

Users consistently praise the remote lock and unlock capability – the ability to grant access from a smartphone while keeping the original exterior deadbolt intact is a frequent highlight. Voice‑assistant integration also receives positive mentions, especially for hands‑free entry. However, the 3.9‑star average from 11,362 reviews points to occasional connectivity glitches and a desire for more robust battery life. The lock runs on two CR123 batteries, which some owners find less convenient than the AA packs used by several competitors.

From a technical standpoint, the lock’s warranty lasts one year and the installation time lists “less than 10 minutes,” making it a solid DIY candidate. The dual‑band Wi‑Fi and Bluetooth 4.0 combo give it a modern connectivity stack, while the lack of an IP rating means you’ll want to keep it away from direct moisture.

Best for: Entry‑level buyers or those on a tight budget

Avoid if: You need powerful performance or professional‑grade features

TL;DR: The Level Lock+ Wi‑Fi Satin Nickel delivers an ultra‑compact, invisible deadbolt with BHMA AAA security, Apple HomeKey support, and a 20‑minute fire rating for $345.99.

What really sets this lock apart is its size – the deadbolt measures just 3.31 in long, 2.25 in high and weighs only 1.07 lb, making it one of the smallest smart deadbolts on the market. It fits doors with a backset of 2.75 in (long) or 2.375 in (short) and a bore hole diameter of 2.125 in, while handling door thicknesses from 1.75 in to 2 in.

Compared with the other ten contenders, Level’s lock is lighter than the Schlage Encode Plus (≈3.0 lb) but heavier than the August Smart Lock Pro (≈0.87 lb) and the ultra‑light August Smart Lock (≈0.175 lb). Its price tag places it at the premium end of the range, so it’s pricier than most of the peers. In terms of weight, it sits between the heavier Ultraloq U‑Bolt Pro (≈2.8 lb) and the lighter Yale Assure (≈1.0 lb).

Users love how the lock blends into the door without a visible keypad, calling it “the most beautifully designed smart lock” and praising the BHMA AAA rating for peace of mind. Professional reviewers note the solid 440C stainless‑steel construction and smooth Apple HomeKey integration. Common complaints focus on the requirement of a separate Wi‑Fi bridge for remote access, occasional Bluetooth/Wi‑Fi hiccups, and the modest 20‑minute fire rating, which some see as a limitation for fire‑door installations.

Technically, it runs on a single CR2 lithium battery with a low‑battery indicator, and it’s compatible with Bluetooth 4.0+ (5.0 recommended). It includes an IPX4 splash‑proof rating, auto‑lock, a weather‑proof wireless keypad that works up to 30 ft, and voice‑assistant support for Apple HomeKit, Alexa, and Google Assistant. Select variants also support Matter for future‑proof smart‑home integration.

Best for: Those who prioritize a sleek, invisible design, high security, and deep Apple HomeKit integration and are willing to invest in a premium smart lock.

Avoid if: You need a low‑budget solution, a lock that works without an extra Wi‑Fi bridge, or a fire‑rating longer than 20 minutes.
