Best Keyless Deadbolts with Biometric Authentication

TL;DR: The Ultraloq Bolt 5‑in‑1 smart deadbolt blends fingerprint, keypad, app, voice and key entry in a compact, IP65‑rated lock that earns 4.3‑star reviews for its ease of installation and Apple Home integration.

The lock’s standout spec is its 5‑way unlock system—fingerprint, keypad, app, voice and two mechanical keys—all backed by a 360° fingerprint sensor that holds up to 50 entries and an anti‑peep keypad that stores up to 50 access codes. It also carries an IP65 rating, 128‑bit AES encryption, and native Matter support over both Wi‑Fi and Thread, making it one of the most versatile options in the lineup.

At 3.4 pounds, the Ultraloq Bolt is heavier than budget‑friendly peers like the Lockstar Smart Door Lock (1.0 pound) and the Wyze Palm Lock (1.9 pounds), yet it’s a touch lighter than the eufy Video Smart Lock (approximately 3.6 pounds). Its 2.96‑inch depth is deeper than Lockstar’s 30 mm depth but more compact than the eufy Video’s 221 mm depth, positioning it solidly in the mid‑range of size and weight. Feature‑wise, few rivals combine Matter/Thread connectivity with an IP65 rating; the Wyze Palm Lock only offers IP53 and lacks Thread support.

Users consistently praise the seamless Apple Home integration, noting that Siri can lock or unlock the door without an extra hub. Reviewers also highlight the straightforward DIY installation and the reliability of the auto‑lock feature. On the downside, some users report that the lock only works with 2.4 GHz Wi‑Fi, which can be a snag for homes that rely on 5 GHz networks, and a few mention that aligning the deadbolt with the existing knob adds a modest amount of installation effort.

The lock meets ANSI/BHMA Grade 1 security standards and runs on eight AA alkaline batteries, with the manufacturer estimating about 10 months of battery life. It operates from –4 °F to 149 °F, and the warranty combines a lifetime mechanical guarantee with an 18‑month electronic guarantee, offering solid peace of mind.

TL;DR: For $66.49, the Ultraloq U‑Bolt 5‑in‑1 Black delivers five keyless entry methods, solid ANSI Grade 1 security and a weather‑proof IP rating in a DIY‑friendly package that weighs 3.0 lbs.

The lock’s standout feature is its five unlock methods—fingerprint, PIN, app, NFC and voice—so you can choose the most convenient way to get inside, whether you’re juggling groceries or juggling a busy schedule. Auto‑lock is built in, and the unit is rated IP65, meaning it can handle rain and dust without a problem.

At 3.0 lbs, the Ultraloq is heavier than the Sifely Fingerprint Smart Deadbolt (2.0 lbs) and the Philips Smart Lock (1.4 lbs), but it still feels solid on a standard door. Compared with the Wyze Palm Lock (1.9 lbs), it adds a bit of heft while packing more entry options. The lock’s Zinc Alloy body and ANSI Grade 1 certification put it on par with higher‑priced competitors, yet its price point keeps it firmly in the budget tier.

Users appreciate the hands‑free fingerprint and voice unlock, noting how quickly they can slip inside without fumbling for a key. Professional reviewers highlight the upgraded auto‑unlock geofencing and the anti‑peep keypad as practical security upgrades. The main trade‑off is that remote features like door‑status alerts often need an optional Wi‑Fi or Z‑Wave bridge, and battery requirements can differ between models, which some owners find inconvenient.

Best for: Budget-conscious buyers seeking a reliable entry‑level option — the Ultraloq U‑Bolt 5‑in‑1 Black offers Weight: 3.0 lbs

Avoid if: You need remote access without purchasing an extra bridge or prefer a lighter‑weight deadbolt.

TL;DR: The Lockstar Smart Door Lock offers a 30 mm depth, adjustable 60‑70 mm deadbolt, multiple entry methods and Alexa/Google Home integration for $139.97, earning 4.6/5 stars from 1,394 reviewers.

What really stands out is the lock’s compact build – a depth of just 30 mm (about 1.2 in) and a height of 164 mm (6.5 in) while still delivering a sturdy 67 mm (2.6 in) width. The deadbolt itself is adjustable between 60 mm and 70 mm, letting you match most door preparations. Weighing only 1.0 pound (454 g), it’s lighter than the Wyze Palm Lock (1.9 pounds) and far lighter than the Ultraloq Bolt (3.4 pounds), which makes it easy to handle during installation.

Compared with the nine other deadbolts in this roundup, Lockstar sits near the top for feature richness. While the Philips Smart Lock with Handle and the Wyze Palm Lock list dimensions and weight, Lockstar’s zinc‑alloy body feels more substantial than the plastic‑cased Philips Smart Lock (1.4 pounds) yet remains lighter than most aluminum options like the eufy Smart Lock C33 (2.0 pounds). Its Bluetooth connectivity is on par with peers, but remote access needs an optional Wi‑Fi gateway, a step not required by the eufy Video Smart Lock E330, which includes built‑in Wi‑Fi.

Users consistently praise the fingerprint scanner for speed and reliability, noting that the Touch ID sensor unlocks the door in a flash. The door‑sensor‑driven auto‑lock activates the moment the door closes, preventing accidental lock‑outs – a point highlighted by professional reviewers. On the downside, buyers report that the package arrives without batteries, so you’ll need to purchase four AA alkaline cells separately, and the extra gateway adds a bit of setup complexity for remote app control.

From a technical standpoint, the lock runs on 6 V supplied by four AA batteries and draws less than 30 µA in standby, keeping power draw low. It tolerates temperatures from –20 °C to 70 °C and humidity between 20 % and 80 % RH, making it suitable for most climates. Security‑focused features such as tamper alerts, anti‑drill and anti‑pick protection, plus activity logs, give extra peace of mind.

TL;DR: The Sifely Fingerprint Smart Deadbolt blends a 5‑in‑1 unlock system, 100+ fingerprint slots, and voice‑assistant support for $76.49, delivering solid security without breaking the budget.

This lock’s standout feature is its five distinct unlocking methods—fingerprint, keypad code, app, fob, and physical key—plus auto‑lock and built‑in voice‑assistant compatibility. It stores more than 100 fingerprints and 100 unique codes, and its zinc‑alloy body measures 6.3 inches deep, 1.9 inches high, and 2.6 inches wide, weighing 2.0 pounds.

Compared with the other nine entries, the Sifely sits in the middle of the weight range: it’s heavier than the Philips Smart Lock at 1.4 pounds but lighter than the Ultraloq U‑Bolt at 3.0 pounds. Its backset of 2 ⅜” or 2 ¾” matches the Wyze Bolt v2, and its door‑thickness compatibility of 1 5/16” to 2” aligns with the Philips Smart Lock’s range. Notably, Sifely’s fingerprint capacity of 100+ dwarfs the Philips model’s 20 slots, giving it a clear edge for households with many users.

Reviewers consistently praise the convenience of having five ways to get in, especially the fingerprint scanner that unlocks in seconds. The auto‑lock feature and low‑battery alerts are also highlighted as handy safety nets. On the downside, users note that remote app control requires a separate Sifely Gateway, and the lock ships without the four AA batteries it needs, adding a small extra purchase.

Additional technical details include an operating temperature range from 14 °F to 158 °F, reversible mounting for left‑ or right‑handed doors, and an anti‑peep code function. Installation is DIY‑friendly, needing only a screwdriver and no drilling, which many homeowners appreciate.

Best for: Budget-conscious buyers seeking a reliable entry‑level option — the Sifely Fingerprint Smart Deadbolt offers Fingerprint Capacity: 100+

Avoid if: You need a fully self‑contained Wi‑Fi lock without purchasing additional hardware.

TL;DR: The Philips Smart Lock packs built‑in Wi‑Fi, a 0.3‑second fingerprint scanner and five unlock methods into a 1.4‑pound deadbolt for $79.98, making it a solid entry‑level smart lock.

The standout spec is the integrated 2.4 GHz Wi‑Fi, which lets you control the lock from the Philips Home Access app without a separate hub. Combined with Bluetooth, AES128 encryption and voice‑assistant compatibility (Alexa, Google), the lock offers a truly wireless experience. Its fingerprint sensor reads a print in just 0.3 seconds with a 99 % recognition rate, and you can store up to 20 fingerprints plus 100 user PINs.

Compared with the other nine locks, the Philips model sits at the lower end of the price range and weighs 1.4 pounds—lighter than the Ultraloq U‑Bolt 5‑in‑1 (3.0 pounds) but a bit heavier than the Lockstar Smart Door Lock (1.0 pound). While the Wyze Bolt v2 shares a similar price point, Philips adds built‑in Wi‑Fi where Wyze relies on Bluetooth only. In the fingerprint arena, Sifely Fingerprint Smart Deadbolt lists a capacity of 100+ prints, so Philips’ 20‑print limit is more modest. The lock also lacks Z‑Wave support, which Ultraloq and Lockstar provide, meaning fewer protocol options but a simpler setup.

Reviewers appreciate the hub‑free Wi‑Fi setup and the quick, reliable fingerprint unlock. Professional reviewers highlight the 0.3‑second recognition speed and the convenience of remote access via the app. The main complaints revolve around the need for eight AA batteries—none are included—and the absence of an emergency power backup. The ANSI/BHMA Grade 3 rating is fine for typical home doors but isn’t meant for commercial‑grade security.

Additional technical notes include an auto‑lock timer that can be set anywhere from 10 to 180 seconds, operation in humidity from 0 % to 95 %, and a temperature range of –35 °C to 66 °C. The lock supports three modes—Manual, Auto, and Away Security—and logs entries locally, giving you a clear record of who entered and when.

TL;DR: The Wyze Palm Lock uses palm‑vein scanning for contactless entry, offers Wi‑Fi and voice‑assistant integration, and installs in about 20 minutes for $129.98.

The standout feature is the palm‑vein biometric sensor, which lets you unlock the door by simply hovering your hand. At 1.9 pounds, it’s heavier than the Lockstar’s 1.0‑pound unit but considerably lighter than the Ultraloq U‑Bolt’s 3.0‑pound design. It earned a 4.5‑star rating from 471 reviewers and ships with a BHMA Grade 3 certification, indicating it passed rigorous durability testing.

Compared with the other nine locks in this roundup, the Palm Lock sits in the mid‑weight range and matches the Ultraloq Bolt’s 50 guest‑code capacity. While the Philips Smart Lock and eufy C33 list fewer biometric options, the Wyze model adds voice‑assistant support, Wi‑Fi connectivity, and a built‑in gyroscope for true auto‑lock detection—features many peers lack or list only vaguely.

Professional reviewers praise the contactless vein scan as harder to spoof than fingerprint readers, and users appreciate the anti‑peep protection on the keypad. The lock’s IP53 rating means it can handle light rain and dust, and the main lithium battery lasts about six months with a two‑week backup reserve. A common complaint is that the USB‑C emergency charging cable isn’t included, so you’ll need to source one separately if the battery runs out.

TL;DR: The eufy Video Smart Lock E330 3‑in‑1 blends a 2K camera, 50‑fingerprint slots and auto‑lock Wi‑Fi control for $199.99, but its battery may need more frequent charging than advertised.

This lock’s headline feature is the built‑in 2K (2560 × 1440) video camera with an f/1.6 aperture and a 5.2 m motion‑detection range, turning the deadbolt into a front‑door surveillance hub. It also supports five unlock methods—fingerprint, app, keypad, voice and physical key—while the fingerprint sensor replies in just 0.3 seconds. The unit is IP65‑rated, can resist 2000 N of pressure, and runs on a rechargeable 10 000 mAh Li‑ion battery that the manufacturer claims lasts 3‑12 months.

At 3.6155810968 pounds, the eufy lock is heavier than the Ultraloq Bolt’s 3.4 pounds and considerably heavier than the Lockstar Smart Door Lock’s 1.0 pound body. Its depth of 221 mm (8.7 in) also exceeds Ultraloq’s 2.96 in depth, meaning it sits a bit farther out from the door edge than some slimmer competitors. Installation requires no drilling, matching the hassle‑free claim of the Ultraloq and offering a quicker fit than the more involved setups of the Wyze Palm Lock.

Reviewers consistently praise the all‑in‑one design, noting that the sharp 2K video and reliable motion alerts make package monitoring easy. However, many users report that the battery drains faster than the official 3‑12 month estimate, even with the large 10 000 mAh pack. The touch‑type keypad and doorbell button are also described as dim at night, which can confuse visitors after dark.

From a durability standpoint, the lock is BHMA‑certified for 100 000 lock cycles and backed by AES128 + ECC encryption, giving peace of mind for long‑term security. It operates from –22 °F to 158 °F and tolerates up to 72 hours of salt spray and 144 hours of humidity, making it suitable for harsh climates. Voice‑assistant support for Alexa and Google Assistant adds hands‑free convenience, while built‑in Wi‑Fi eliminates the need for an external hub.

Best for: Those prioritizing quality and willing to pay for premium performance — the eufy Video Smart Lock E330 3‑in‑1 offers Fingerprint Capacity: 50

Avoid if: You're shopping on a tight budget — it's priced at $199.99

TL;DR: The Philips Smart Lock with Handle costs $115.99, offers hub‑free 2.4 GHz Wi‑Fi, a 0.3‑second fingerprint scanner and up to 100 PIN codes, making it a solid mid‑range choice for tech‑savvy homes.

The lock’s standout feature is its built‑in 2.4 GHz Wi‑Fi, so you can control it from the Philips Home Access app without a separate hub. Inside, the fingerprint sensor reads a print in just 0.3 seconds and supports 20 fingerprints, while the keypad can store 100 user PINs – a handy mix for families and frequent guests.

At 1.5 inches tall and 6.0 inches long, it’s far slimmer than the eufy Smart Lock C33’s 5.12‑inch height and 7.24‑inch length, yet its 2.2‑inch width is a touch narrower than the Lockstar Smart Door Lock’s roughly 2.64‑inch width. Compared with the Wyze Palm Lock, the Philips unit’s length is comparable to the Palm’s 156 mm external dimension, but it sits a bit higher in price than the Wyze model.

Reviewers love the effortless app and voice‑assistant integration, noting that the quick fingerprint entry feels “instant” and that the auto‑lock timer (10‑180 seconds) helps prevent forgotten locks. Some users mention that the Wi‑Fi connection can drain the eight AA batteries faster than expected, and a few have run into occasional app hiccups on non‑2.4 GHz networks.

Security‑focused details include AES128 encryption stored locally and an ANSI/BHMA Grade 3 rating. The lock works with doors 1‑3/8 inches to 2 inches thick and tolerates temperatures from –35 °C to 66 °C, so it’s suited for most residential entryways.

Best for: Buyers in the mid price range seeking the best quality at that price point — the Philips Smart Lock with Handle offers Fingerprint Capacity: 20

Avoid if: You're shopping on a tight budget — it's priced at $115.99

TL;DR: The eufy Smart Lock C33 costs $99.99, fits a 5.12‑inch height, and blends adaptive fingerprint entry with built‑in Wi‑Fi for a solid, renter‑friendly deadbolt.

The lock’s most eye‑catching spec is its integrated Wi‑Fi that works straight from the lock—no bridge or hub required. Pair that with adaptive fingerprint recognition that learns the grip of each user, and you get one‑handed entry that families rave about. Physically, the unit measures 7.24 inches long, 6.06 inches wide, and 5.12 inches high, giving it a sturdy presence on most standard doors.

At $99.99, the C33 sits above the Ultraloq U‑Bolt 5‑in‑1 but well below the Lockstar Smart Door Lock, positioning it in the mid‑range price tier. It offers more unlock methods than many peers—fingerprint, keypad, NFC card, app, and a physical key—yet it lacks Matter support and video integration that premium competitors provide. In short, it delivers a richer feature set than the basic Wyze Bolt v2 while staying simpler than the higher‑priced, feature‑heavy options.

Everyday users highlight the effortless family use: the fingerprint‑handle combo unlocks quickly, the back‑lit anti‑peep keypad prevents shoulder‑surfing, and the privacy mode’s red light signals exterior lockout. Reviewers also note the 15‑minute, no‑drill installation and an 8‑12‑month battery life on eight AA cells, which suits renters and Airbnb hosts. On the downside, professional reviewers point out the BHMA Grade 3 rating—acceptable for most homes but lower than Grade 1 models—and the reliance on replaceable AA batteries, which some high‑traffic users find inconvenient. Wet fingers and occasional keypad lag also surface in consumer feedback.

Additional technical context includes an IP53 rating that guards against splashing water, an aluminum body with a matte anodized finish for durability, and compatibility with both left‑ and right‑hand doors. Auto‑lock can be set with a countdown timer, and the lock integrates with Amazon Alexa and Google Assistant for voice‑controlled access.

Avoid if: you need the highest security rating (Grade 1) or integrated video doorbell features.

TL;DR: The Wyze Bolt v2 delivers Wi‑Fi remote access, a fast 0.3‑0.5 s unlock, and a 15‑minute install for $79.98, making it a solid budget smart deadbolt.

What really sets the Wyze Bolt v2 apart is its built‑in 2.4 GHz Wi‑Fi, which lets you lock or unlock from anywhere without a separate hub, and an AI‑driven fingerprint scanner that opens the door in just 0.3‑0.5 seconds. The lock weighs 2.5 lb and fits standard US doors with a backset of 2‑3/8" or 2‑3/4".

Compared with the other nine options, the Wyze Bolt is lighter than the Ultraloq U‑Bolt 5‑in‑1 Black (3.0 pounds) but heavier than the Philips Smart Lock (1.4 pounds) and the Sifely Fingerprint Smart Deadbolt (2.0 pounds). Like the Ultraloq, it offers native Wi‑Fi, while the Lockstar Smart Door Lock needs an optional gateway for connectivity. Its backset and cross‑bore dimensions match those of Philips and Sifely, so most single‑cylinder deadbolts will accept it without drilling.

Users repeatedly praise the lock’s reliable fingerprint entry and the fact that installation usually finishes in about 15 minutes. Reviewers also note the long‑lasting 8‑month battery life, but several point out that the auto‑lock timer doesn’t detect whether the door is closed, which can lead to accidental lock‑ins. Professional reviewers highlight the tempered glass keypad’s anti‑peep and anti‑glare surface, and the BHMA Grade 2 certification adds a layer of confidence for budget‑focused homeowners.

Technical details reinforce its value: the unit carries an IP53 rating for splash resistance, stores data locally with hardware encryption, and runs on eight AA batteries with a USB‑C emergency power port. The lock’s setup range reaches 16 ft, and its compact external dimensions (156.5 mm × 72 mm × 17.3 mm) keep it unobtrusive on the door.

Best for: Entry‑level buyers or those on a tight budget — the Wyze Bolt v2 offers Installation Time: 15 minutes
