Also considered
TL;DR: The Ultraloq Bolt blends a 360° fingerprint scanner, Matter‑over‑Thread Wi‑Fi, and an IP65‑rated zinc‑alloy body at 3.4 lb, delivering high‑grade security for a mid‑range price.
What really sets the Bolt apart is its native Matter support over both Wi‑Fi and Thread, letting you lock or unlock from Apple Home, Google Home, or Alexa without a separate hub. The lock also packs a 360° fingerprint sensor, an anti‑peep keypad, and Access Codes Capacity of up to 50, plus two mechanical keys for backup. Its compact dimensions—2.96 in depth and height, and 1.35 in width—keep the exterior sleek while the zinc‑alloy case carries an IP65 rating for weather resistance.
In this nine‑product roundup, the Bolt sits at a higher price tier than the eufy Smart Lock C33 and the Ultraloq U‑Bolt, yet it’s cheaper than the Schlage Encode Plus and Yale Assure Lock. Feature‑wise, it offers Matter and Thread connectivity—a capability not listed for most peers—while the Yale Assure SL Black Suede focuses on Bluetooth and Wi‑Fi only. Compared with the Veise VE012W, the Bolt provides a stronger ANSI/BHMA Grade 1 certification and a more robust 128‑bit AES encryption suite.
Everyday users highlight the convenience of remote lock/unlock via the U‑home app and the seamless Siri voice commands that come straight out of the box. Reviewers also note the lock’s DIY‑friendly installation, though a few mention that the separate deadbolt/knob arrangement can add a step for newcomers. A recurring theme is the lock’s reliance on a 2.4 GHz Wi‑Fi network, which can be a hiccup if your router defaults to 5 GHz only. Professional reviewers praise the efficient power management through Thread, extending battery life on eight AA cells.
Beyond the smart features, the Bolt meets ANSI/BHMA A156.36 Grade 1 standards and encrypts communications with 128‑bit AES. It tolerates external temperatures from –4 °F to 149 °F and internal ranges from 14 °F to 131 °F, ensuring reliable operation year‑round.
Pros
Cons
Best for: Apple Home users seeking native Siri integration and a lock that works across major smart‑home ecosystems without a hub — the Ultraloq Bolt offers Access Codes Capacity: Up to 50
Avoid if: You need 5 GHz Wi‑Fi compatibility or prefer a lock with a snap‑on installation that requires minimal setup.
“Built-in WiFi, app remote control, and door alerts.”
TL;DR: The Ultraloq U‑Bolt 5‑in‑1 Black delivers 120‑fingerprint capacity, Matter‑over‑Thread support, and a solid $66.49 price point, all in a 3.0 lb deadbolt.
What really sets this lock apart is its 360° capacitive fingerprint sensor that stores up to 120 fingerprints, paired with an IP65‑rated housing for weather resistance. The lock also supports NFC (up to 50 keys) and a backlit anti‑peep keypad that holds 50‑60 PIN codes, giving you many ways to get in without a traditional key.
At 3.0 lb, the U‑Bolt is heavier than the Philips Smart Lock’s 1.4 lb body but lighter than the Schlage Encode Plus’s 3.4 lb construction, placing it in the middle of the weight range for this roundup. Its $66.49 list price lands it well below premium models like the Yale Assure SL Black Suede, making it a budget‑friendly alternative that still packs a full feature set.
Users consistently praise the hands‑free unlock experience, especially when juggling groceries, while professional reviewers note the improved auto‑unlock geofencing and configurable auto‑lock timer (10 seconds to 5 minutes). The main drawback is that remote door‑status alerts and smart auto‑lock often require an optional Wi‑Fi or Z‑Wave bridge, and battery configurations can differ between 4 and 8 AA cells.
From a technical standpoint, the lock runs 128‑bit AES encryption, offers Alexa, Google Assistant, and SmartThings voice integration, and provides a 1‑year battery life for up to 8,000 accesses via its 8 × AA alkaline pack. A micro‑USB backup port ensures you won’t be locked out if the batteries die.
Pros
Cons
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 additional bridge, or you prefer a lighter lock for a narrow door frame.
TL;DR: The Yale Assure SL Black Suede blends a premium suede‑finished zinc body with up to 250 user codes, integrated Wi‑Fi/Bluetooth, and a slim 0.69‑in depth, making it a top‑tier smart deadbolt for tech‑savvy homes.
What really sets this lock apart is its capacity to store up to 250 unique access codes and an adjustable backset of 60‑70 mm, giving you plenty of flexibility for families or short‑term rentals. The lock sits just 0.69 in deep, 3.56 in tall and 2.56 in wide, so it fits neatly on most standard doors without protruding into the entryway.
Compared with the other eight contenders, Yale’s height (3.56 in) is taller than the Ultraloq Bolt’s 2.96 in but shorter than the eufy Smart Lock C33’s 5.12 in. Its depth of 0.69 in is far shallower than Ultraloq Bolt’s 2.96 in, meaning it sits closer to the door surface. The user‑code capacity dwarfs the Ultraloq Bolt’s 50 codes and even exceeds the Schlage Encode Plus’s 100 codes. While the base model includes Wi‑Fi and Bluetooth, Z‑Wave and ZigBee require separate modules, unlike some peers that ship with those radios built in.
Everyday owners love the keyless touchscreen and the convenience of voice control through Amazon Alexa, Google Assistant or Siri. Reviewers repeatedly mention the straightforward retrofit installation that only needs a screwdriver, and they appreciate the 24/7 activity logs that keep them informed. On the flip side, users flag the need to monitor four AA batteries and the extra cost of optional Z‑Wave/ZigBee add‑ons. Professional reviewers also note the lock’s durability, citing a stress‑test rating of over 2,000 operational cycles and its RCM compliance (EN 61000.6.3 2012 & EN 55032 2016).
Pros
Cons
Best for: Those prioritizing quality and willing to pay for premium performance — the Yale Assure SL Black Suede offers Backset: Adjustable 60-70mm
Avoid if: Reliability and user satisfaction are your top concerns
TL;DR: The Schlage Encode Plus is a premium Wi‑Fi deadbolt that blends Apple Home Keys NFC access, 100 user codes and a lifetime mechanical warranty for $319.00, but its price and six‑month battery life may deter budget‑focused buyers.
What really sets the Encode Plus apart is its built‑in 2.4 GHz Wi‑Fi, meaning you get remote lock control straight from the Schlage Home app without a separate hub. It also supports Apple Home Keys, letting you unlock the door with an iPhone or Apple Watch by tapping within a few inches. The lock stores up to 100 access codes and runs on four AA alkaline batteries that the manufacturer says last about 6 months.
Compared with the eight other locks in this roundup, the Encode Plus sits at the higher end of the price spectrum and is heavier than the Philips Smart Lock (1.4 pounds) and the Veise matte‑black model (1.68 pounds), but it matches the Ultraloq Bolt’s 3.4 pounds. It also offers more access codes than the Ultraloq U‑Bolt (up to 50) and the Philips lock (no code count listed), though the Yale Assure SL Black Suede can hold up to 250 codes. In short, you’re paying for a richer feature set and a sturdier build.
Consumer chatter highlights a smooth installation experience guided by the Schlage app, and many users applaud the instant NFC unlock via Apple Home Keys. On the flip side, reviewers repeatedly point out the $319.00 price tag as steep compared with Bluetooth‑only alternatives, and the need to replace batteries every six months is seen as a maintenance hassle. Professional reviewers also note the lack of an IP rating, which could be a concern for exposed exterior doors.
From a technical standpoint, the lock uses 128‑bit AES encryption and meets ANSI/BHMA Commercial Grade 3 (AAA) standards, giving it strong security credentials. Its backset is universal (adjustable to 60‑70 mm), and it fits doors 35‑45 mm thick, covering most residential entryways. The deadbolt also features a built‑in alarm with selectable sensitivity, low‑battery alerts, and auto‑lock functionality.
Pros
Cons
Best for: Those prioritizing quality and willing to pay for premium performance — the Schlage Encode Plus offers Access Codes Capacity: 100
Avoid if: You’re not an Apple ecosystem user or you need a lower‑cost lock without frequent battery changes
TL;DR: The Philips Smart Lock delivers built‑in Wi‑Fi and Bluetooth, fast 0.3‑second fingerprint entry, and a lightweight 1.4‑lb deadbolt for under $80, making keyless home access simple.
The standout feature is its integrated Wi‑Fi plus Bluetooth, so you never need a separate hub. Fingerprint access works in just 0.3 seconds and hits a 99% recognition rate, letting you unlock the door with a quick touch. The lock also supports PIN codes, a mechanical key, voice commands, and remote control through the Philips Home Access app.
At 1.4 pounds, the Philips lock is noticeably lighter than the Ultraloq U‑Bolt (which tips the scales at 3.3–3.5 lbs) and the Veise VE012W (about 1.68 lb). Its 6‑inch length makes it longer than the Ultraloq U‑Bolt’s 2.95‑inch profile, giving it a more substantial feel on the door edge while still staying compact enough for most standard doors.
Reviewers appreciate the hub‑free Wi‑Fi setup and the rapid fingerprint response, calling the lock “quick and reliable.” Professional reviewers highlight the AES128 encryption and the flexible auto‑lock window of 10‑180 seconds as solid security touches. The main complaints focus on the need for eight AA batteries (which aren’t supplied) and the lack of an emergency power backup, while the ANSI/BHMA Grade 3 rating is noted as suitable for residential use but not for heavy‑duty commercial settings.
Pros
Cons
Best for: Budget-conscious buyers seeking a reliable entry-level option — the Philips Smart Lock offers Backset: 2-3/8 or 2-3/4 inch
Avoid if: You need advanced features or professional‑grade performance
TL;DR: The eufy Smart Lock C33 delivers integrated Wi‑Fi, adaptive fingerprint access and a compact 5.12‑inch height for $99.99, making it a solid mid‑range pick for families, renters and small‑business owners.
What really sets the C33 apart is its built‑in Wi‑Fi that talks straight to the eufy app – no bridge or hub needed. The lock runs on eight AA alkaline batteries that the manufacturer says last 8‑12 months, and its IP53 rating protects it from light rain or splashes. At 5.12 inches tall, 7.24 inches long and 6.06 inches wide, it’s a fairly compact deadbolt, and the back‑lit anti‑peeping keypad together with a privacy‑mode red‑light indicator adds a layer of visual security.
Compared with the other eight contenders, the C33 is taller than the Ultraloq U‑Bolt’s 2.95‑inch height and the Philips Smart Lock’s 1.5‑inch profile, while still shorter than the Yale Assure Lock’s 6.06‑inch height. Its width of 6.06 inches dwarfs Ultraloq’s 0.99‑inch width but is comparable to the Yale models that sit around 2.5‑2.75 inches. In the connectivity arena, eufy’s integrated Wi‑Fi matches the Veise VE012W and Yale Assure SL, both of which also list built‑in Wi‑Fi, and it outpaces the Ultraloq U‑Bolt and Ultraloq Bolt that rely on Bluetooth or separate hubs. Feature‑wise the C33 offers fingerprint, keypad, NFC card, physical key and remote app control – a broader mix than many peers that list only a few unlock methods.
Users consistently praise the lock’s “one‑handed” fingerprint entry, noting that the adaptive sensor learns the grip of each family member for quick access. Installation is described as a “15‑minute, no‑drill” job, which renters and Airbnb hosts love because it leaves the door untouched. On the downside, reviewers mention occasional hiccups when fingers are wet, faster battery drain in high‑traffic homes, and occasional keypad lag in low‑light conditions. Professional reviewers echo these points, calling the biometric integration “seamless” but flagging the BHMA Grade 3 rating as a step down from premium Grade 1 locks.
Additional technical details include a 18‑month warranty, a countdown auto‑lock timer, and support for Amazon Alexa and Google Assistant voice commands. The lock works on both left‑ and right‑hand doors, and its matte anodized aluminum finish gives it a sleek, low‑profile look that blends into most door styles.
Pros
Cons
Best for: Most users seeking a balanced, mainstream option — the eufy Smart Lock C33 offers Height: 5.12 inches
TL;DR: The Ultraloq U‑Bolt delivers hub‑free Wi‑Fi, 8‑in‑1 entry and solid build at $79.99, making it a versatile, mid‑range smart lock for tech‑savvy homes.
What really sets the U‑Bolt apart is its built‑in 802.11 b/g/n (2.4GHz) Wi‑Fi, so you get remote access and auto‑unlock without a separate hub. The lock measures a compact 2.95 inches in height and length, and weighs between 3.3 lb and 3.5 lb, giving it a sturdy feel while still fitting standard door jambs.
Compared with the other eight contenders, the U‑Bolt lands in the mid‑price tier – cheaper than the Yale Assure SL Black Suede but pricier than the Veise VE012W. It’s heavier than the Philips Smart Lock (1.4 lb) and the Veise (1.68 lb), yet comparable to the Ultraloq Bolt (around 3.4 lb), so it feels solid without being overly bulky.
Everyday users praise the intuitive app, reliable remote control, and instant door‑status alerts, especially noting the IP65 rating and ANSI/BHMA Grade 1 certification for durability. Professional reviewers highlight the configurable auto‑lock timing from 10 seconds to 5 minutes and the geofencing improvements over earlier models. Some users do report that the lock’s reliance on 2.4 GHz Wi‑Fi can limit connectivity in crowded networks, and the constant Wi‑Fi draw may shorten the life of the eight AA alkaline batteries.
Technical details add further confidence: the lock uses 128‑bit AES encryption, supports up to 50 fingerprints, 50 NFC keys and 50 passcodes, and offers an adjustable backset of 2‑3/8" or 2‑3/4". It fits doors 1‑3/8" to 1‑3/4" thick, with a face‑hole size of 2‑1/8". The included door sensor and micro‑USB backup charging port round out its feature set.
Pros
Cons
Best for: Value-conscious buyers seeking quality at $79.99 — the Ultraloq U‑Bolt offers Backset: 2-3/8" or 2-3/4" (adjustable)
Avoid if: You need advanced features or professional‑grade performance
“Engineering excellence”
TL;DR: The Yale Assure Lock blends a premium oil‑rubbed bronze finish with fingerprint, keypad and voice entry, but its $319.99 price and need for a separate Wi‑Fi module keep it in the high‑end niche.
The lock’s standout dimension is its depth of 1.38 Inches, giving it a substantial feel that matches the heavy‑duty 4.5 pounds weight. Inside, the 6.06 Inches tall, 2.75 Inches wide body houses a fingerprint sensor, a touchscreen keypad, and a traditional key cylinder, all protected by advanced encryption and tamper alarms.
Compared with the eight other smart deadbolts in this roundup, the Yale sits at the top of the price ladder and is noticeably heavier than the Schlage Encode Plus (3.4 pounds) and Ultraloq Bolt (3.4 pounds). Its 1.38 Inches depth also exceeds the Yale Assure SL Black Suede’s 0.69 Inches depth, making it one of the bulkier options. While its 4.1/5‑star rating from 800 reviews trails the 4.3‑plus scores of several peers, users still praise its robust feature set.
Consumer sentiment highlights the lock’s “approximately 1 year” battery life on four AA alkaline cells and the convenience of hands‑free auto‑unlock via Bluetooth (range ~15 feet). Professional reviewers note the “advanced encryption and tamper alarms” as a strong security advantage, and many families appreciate the ability to share up to 250 guest codes when the Wi‑Fi module is installed. However, the requirement for a separate Wi‑Fi module to unlock remotely can be a stumbling block for users without reliable home Wi‑Fi.
Pros
Cons
Best for: Those prioritizing quality and willing to pay for premium performance — the Yale Assure Lock offers Depth: 1.38 Inches
Avoid if: You're on a tight budget, need a lightweight lock, or lack reliable Wi‑Fi for remote access
TL;DR: For just $49.98, the Veise VE012W Matte Black delivers Wi‑Fi‑direct control, built‑in fingerprint access, and a sturdy zinc‑alloy body in a compact 3.0‑inch depth package.
The lock’s standout feature is its built‑in Wi‑Fi, which lets you control the deadbolt from the KK Home app without any extra hub. It also houses a fingerprint sensor that unlocks the door in a flash. Physically, the unit measures 3.0 inches deep, 5.1 inches high, and 1.3 inches wide, while weighing a modest 1.68 pounds—light enough for most standard door preparations.
Compared with the other eight contenders, the Veise is lighter than the Ultraloq U‑Bolt 5‑in‑1 Black (3.0 pounds) but a touch heavier than the Philips Smart Lock (1.4 pounds). Its height of 5.1 inches exceeds the Philips model’s 1.5‑inch profile, giving it a more robust presence on the door. Price‑wise, it lands well below many premium options, making it one of the most affordable choices in the lineup while still packing a full suite of access methods.
Professional reviewers praise the fingerprint scanner for its speed and the Wi‑Fi connectivity for enabling remote lock management. However, they also note that the initial Wi‑Fi setup can require some troubleshooting, a sentiment echoed by several user comments. The lock runs on eight AA batteries, which isn’t included and may add to long‑term upkeep costs—something buyers should keep in mind. Still, the IP55 rating and an operating temperature range from –4°F to 131°F mean the unit can handle outdoor exposure without issue, and its BHMA/ANSI Grade 3 certification assures a baseline level of security.
Pros
Cons
Best for: Entry-level buyers or those on a tight budget — the Veise VE012W Matte Black offers Depth: 3.0 inches
Avoid if: You need high‑security certifications beyond Grade 3 or a hub‑centric smart‑home ecosystem
