Best Budget Smart Lock Controllers Under $150

TL;DR: The Sifely Smart Lock packs 200+ fingerprint slots, 150+ passcodes and a 200‑plus fob capacity into a lever‑style lock that installs without drilling for $67.97.

What really sets the Sifely apart is its depth of access options. It stores more than 200 fingerprints, over 150 passcodes and supports 200+ wireless key fobs or cards, all protected by white‑box cryptography and an anti‑peeping code overlay. The lever‑handle design fits a 2 1/8‑inch bore and the unit measures 1.12 inches high, 7.0 inches long and 3.0 inches wide, weighing 3.6 lbs.

Compared with the six other locks in this roundup, the Sifely is heavier than the Ultraloq U‑Bolt 5‑in‑1 (3.0 lbs) but lighter than the Kwikset SmartCode 917 (about 4.14 lbs). Its fingerprint capacity of 200 dwarfs the Wyze Bolt’s 50 slots, and its passcode storage exceeds the 30‑code limit of the Kwikset SmartCode. Installation time of 10–20 minutes matches the Wyze Bolt’s 20‑minute claim and is quicker than many deadbolt‑style units that require drilling.

Users consistently praise the lock’s straightforward setup and the convenience of multiple unlock methods for kids, seniors or guests. Professional reviewers note the sub‑0.3‑second fingerprint read under ideal conditions, while everyday owners flag slower or failed reads when fingers are wet or greasy. The lock also lacks an explicit weather‑proof rating, so it’s best kept on sheltered entryways rather than fully exposed doors in harsh climates.

Technical highlights include a 1‑year battery life powered by four AA cells, Bluetooth connectivity for iOS and Android apps, and voice‑assistant control via a separate Wi‑Fi gateway. The zinc‑alloy construction gives a solid feel despite the modest $67.97 price, and the included two physical keys provide a reliable emergency override.

Best for: Families or households that need many easy‑to‑manage unlock methods – the Sifely Smart Lock offers Fingerprint Capacity: 200.

Avoid if: You need a lock for a fully exposed exterior door in harsh climates or require a completely waterproof solution.

TL;DR: The Yamiry Smart Knob offers 100‑fingerprint slots, five keyless entry methods and DIY setup for $64.50, making it a solid budget pick, though it needs a separate Wi‑Fi gateway for remote access.

At just 5.5 inches long, 0.79 inches high and 2.95 inches wide, the Yamiry Smart Knob packs a 100‑fingerprint capacity into a compact matte‑black form factor. It supports six unlock methods—fingerprint, keypad (6‑9 digit codes), IC card, smartphone app, mechanical key and Alexa voice—plus a low‑battery indicator and privacy mode that blocks non‑admin access from the outside.

Compared with the seven‑product field, Yamiry’s $64.50 price lands it below the Kwikset SmartCode’s $90.92 tag and in line with the Ultraloq U‑Bolt’s $66.49 price point. Its 100 fingerprint slots outnumber Wyze Bolt’s 50 but fall short of Sifely’s 200‑slot offering. In length, Yamiry’s 5.5‑inch body is shorter than Sifely’s 7.0‑inch unit and lighter‑looking than the 3.6‑pound Sifely, though weight isn’t listed for Yamiry. It also includes the same two mechanical keys as Ultraloq’s key‑override option.

Users repeatedly praise the convenience of five distinct entry methods and note that the fingerprint scanner works reliably for kids and teens. Professional reviewers highlight the privacy mode and the fact that installation only requires a screwdriver—no extra drilling. However, several owners report Bluetooth pairing hiccups that sometimes demand a reset, and the need for a separate Wi‑Fi gateway to unlock the door when you’re away.

Battery life stretches 6‑9 months on four AA alkaline cells, and the lock offers an emergency micro‑USB 5 V input for power‑bank backup. Remote access works through the TTLock or Nice DiGi apps, while Alexa integration arrives via a Wi‑Fi gateway. The DIY installation fits standard American wooden doors with a 40‑50 mm thickness range and a 60 mm backset, making it a straightforward upgrade for most homes.

Best for: Budget‑conscious buyers seeking a reliable entry‑level option — the Yamiry Smart Knob offers Fingerprint Capacity: 100

Avoid if: You need native Wi‑Fi connectivity or are securing a high‑security exterior door where a lever‑style lock is preferred

TL;DR: The Wyze Bolt delivers a 16‑ft Bluetooth range, 20‑minute DIY install, and space for 50 fingerprints at a modest $79.98, making keyless entry surprisingly affordable.

The standout spec is its 16‑ft Bluetooth range, which lets you lock or unlock from across most rooms without a hub. Coupled with a 20‑minute installation time, the lock replaces an existing deadbolt without wiring, and its 2.75‑lb body keeps the hardware light enough to handle without extra support.

Compared with the six other smart locks in this roundup, the Wyze Bolt is lighter than the Sifely Smart Lock (3.6 lb) and the Ultraloq U‑Bolt (3.0 lb), yet a touch heavier than the eufy Smart Lock C30 (about 2.09 lb). It also undercuts the Kwikset Home Connect 620’s weight of roughly 3.4 lb, positioning it in the middle of the pack while offering a longer Bluetooth reach than many peers that don’t list a range at all.

User sentiment consistently praises the quick 20‑minute install and the reliable fingerprint storage of up to 50 users. Reviewers also note the backlit anti‑peep keypad and the customizable auto‑lock as convenient daily features. Professional reviewers highlight the BHMA and UL 20‑minute fire‑rated certification, confirming that the lock meets recognized durability standards. The only recurring complaint is the Bluetooth‑only limitation, which caps remote access to the 16‑ft range and can cause occasional app sync delays when you step outside that radius.

Best for: Buyers willing to invest in a proven, high‑quality option — the Wyze Bolt offers Installation Time: 20 minutes

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

TL;DR: The Ultraloq U‑Bolt 5‑in‑1 Black delivers 5‑way keyless entry, 128‑bit AES encryption, and a 3 lb design for $66.49, making it a solid budget smart deadbolt.

What really sets this lock apart is the breadth of entry options. It supports fingerprint, PIN, NFC/Apple Home Key, app control, and voice assistants, with a 360° capacitive sensor that can store up to 120 fingerprints. The auto‑lock timer is configurable from 10 seconds to 5 minutes, and the unit carries an IP65 rating for rain and dust protection. Matter‑over‑Thread compatibility means you can link it directly to Apple Home, Google Home, or Alexa without a separate hub.

Compared with the six other locks in our roundup, the Ultraloq sits in the middle of the weight range—heavier than the Kwikset SmartCode 917 (2.5 lb) but lighter than the Sifely Smart Lock (3.6 lb). Its fingerprint capacity of 120 is lower than Sifely’s 200 but higher than Wyze Bolt’s 50. The lock also offers more connectivity options than the eufy Smart Lock C30, which lacks fingerprint support altogether, and it provides Matter‑over‑Thread where most peers list only Bluetooth or Z‑Wave.

User feedback highlights the convenience of hands‑free unlocking when carrying groceries, and reviewers praise the anti‑peep backlit keypad for added security. A recurring theme is that remote status checks and smart auto‑lock often need an optional Wi‑Fi or Z‑Wave bridge, which adds a small extra cost. Battery life is listed as up to one year or 8 000 accesses, and the lock uses a micro‑USB backup power port—both points that users appreciate for peace of mind.

Best for: Budget‑conscious buyers seeking a reliable entry‑level option — the Ultraloq U‑Bolt 5‑in‑1 Black offers a compact 3.0 lb design.

Avoid if: You want the best value‑per‑dollar in its price range.

TL;DR: The eufy Smart Lock C30 packs built‑in Wi‑Fi, a 5‑month AA‑battery life and a compact 65.28 mm depth for just $54.99, making it a solid budget pick for standard doors.

The lock’s standout feature is its built‑in Wi‑Fi, which lets you control access from the eufy Security app without a separate bridge. Physically, it measures 65.28 mm deep, 153.67 mm tall and weighs only 949.9 g, so it sits neatly on most door frames while staying lightweight.

Compared with the six other locks in this roundup, the C30 is noticeably lighter than the Ultraloq U‑Bolt (3.0 lb) and the Sifely Smart Lock (3.6 lb), and even lighter than the Kwikset Home Connect (1,539 g). It’s also slimmer than the Kwikset SmartCode’s 3.87‑inch depth. Price‑wise it lands at the lower end of the group, while offering Wi‑Fi support that the Ultraloq advertises only via Thread and Matter. However, the C30 lacks Apple HomeKit, IFTTT and Matter compatibility, which the Ultraloq and some peers list.

Professional reviewers highlight the 15‑minute, no‑drill installation and the auto‑lock timer that activates after the door closes. Users repeatedly praise the five‑month battery life on four AA cells and the wrong‑try protection that temporarily locks the unit after repeated errors. The lock’s IPX3 rating and operating temperature range from –22 °F to 158 °F reassure homeowners that it can handle outdoor exposure. On the downside, the battery pack isn’t included, and the 4.1 / 5 star rating sits a notch below many competitors.

Best for: Shoppers on a tight budget who want the most for their money — the eufy Smart Lock C30 offers Depth: 65.28 mm

TL;DR: The Kwikset SmartCode 917 blends a sturdy metal build with 30 user codes, SmartKey rekeying and a three‑year battery life, but it lacks the wireless hub features of many rivals.

The lock’s standout spec is its 30 programmable user codes plus a one‑time code capacity, all managed from a backlit keypad. Its metal housing measures 9.49 inches high, 4.11 inches wide and 3.87 inches deep, and it weighs a solid 4.14 pounds, giving it a premium feel on the door.

Compared with the six other models in this roundup, the SmartCode 917 is the heaviest – heavier than the Wyze Bolt (2.75 lb), eufy C30 (≈2.09 lb) and Ultraloq U‑Bolt (3.0 lb) and even the Sifely Smart Lock (3.6 lb). It also offers fewer built‑in smart‑home connections; while the Wyze Bolt and Ultraloq include Bluetooth or Z‑Wave, the Kwikset base unit provides only limited Alexa/Google integration and no native hub support.

Homeowners consistently praise the lock’s solid metal construction and the ease of rekeying with SmartKey, noting that the battery lasts up to three years on a single 9 V cell. Reviewers do point out that every user code must be entered manually during setup, which can feel tedious, and the lack of native Z‑Wave or Wi‑Fi means remote access isn’t available out of the box.

Additional technical details include a UL‑rated 20‑minute fire protection, auto‑lock intervals ranging from 30 seconds to 10 minutes, a low‑battery indicator, and an adjustable backset of 2‑3/8 or 2‑3/4 inches to fit most doors. The lock also features an intrusion alarm that disables the keypad for one minute after three incorrect attempts.

Best for: Buyers willing to invest in a proven, high‑quality option — the Kwikset SmartCode 917 offers One-Time Code Capacity: Yes

Avoid if: You're on a tight budget, need native Z‑Wave or Bluetooth hub integration, or prefer a lighter, lower‑priced lock.

TL;DR: The Kwikset Home Connect 620 offers Z‑Wave long‑range connectivity, 250 user codes, SmartKey re‑keying, and an illuminated keypad for $149.05, but its premium price and hub requirement may deter budget‑focused buyers.

The standout spec is its Z‑Wave 700 Long Range module, delivering a mesh range of up to 320 ft and a line‑of‑sight reach of up to 1 mile. Combined with S2 encryption and 128‑bit AES, the lock secures remote commands while supporting up to 250 programmable user codes and a 10‑digit illuminated keypad.

Compared with the six other locks in this roundup, the Home Connect 620 is heavier than the Wyze Bolt (2.75 lb) and Ultraloq U‑Bolt (3.0 lb) but lighter than the Kwikset SmartCode 917 (4.14 lb). Its user‑code capacity of 250 far exceeds the 30 codes of the SmartCode 917 and the 150+ codes listed for the Sifely Smart Lock, positioning it as the most flexible option for larger households. At $149.05, it sits at a higher price tier than the sub‑$80 competitors, but it also packs more advanced Z‑Wave features than the Bluetooth‑only Wyze Bolt.

Everyday owners repeatedly mention the reliable keypad response and the convenience of SmartKey re‑keying, which lets you match the deadbolt to existing house keys without a locksmith. Professional reviewers highlight the lock’s long‑range Z‑Wave reach and the “Excellent” battery efficiency that comes from the Z‑Wave‑optimized design. Users also appreciate voice‑assistant integration with Alexa and Google Assistant, as well as the auto‑relock and one‑touch locking functions.

Technical details reinforce its security pedigree: the lock carries an ANSI/BHMA Grade 2 rating, a UL 20‑minute fire rating, and a bump‑guard‑enabled SmartKey mechanism. It operates from –40 °F to 150 °F outdoors and supports SmartStart for a smoother setup with compatible hubs.

Best for: Buyers willing to invest in a proven, high‑quality option — the Kwikset Home Connect 620 offers User Code Capacity: 250

Avoid if: You're shopping on a tight budget — it's priced at $149.05
