What Tips the Decision
A hands-free lock lives or dies on two specifications a spec sheet barely surfaces, namely whether the biometric still recognizes you on an unlit porch and how many backup methods recover the entry when a scan misreads. In roundups from outlets like TechRadar and Tom's Guide, infrared face cameras and palm-vein readers retracting the bolt within 0.6 seconds keep working in darkness because they perceive beneath the skin, whereas a flat 2D camera fails once the porch light extinguishes. Three of the 7 locks in this roundup read your actual face, and the rest interpret the vein pattern in your palm.
The Lockly Visage Zeno consequently leads our weighted SHE Hands-Free Reliability Score, with SwitchBot's structured-light Lock Vision Pro second, the eufy FamiLock S3 Max the palm-vein selection, and the TCL D1 Pro reading your hand in 0.3 seconds. Every lock complements our

The
Lockly Visage Zeno Series Facial Recognition Deadbolt
earns 8.8 on the weighted SHE Hands-Free Reliability Score, the highest composite here, the dual-IR face lock you approach without raising a hand and back with the deepest fallback stack. That 8.8 rests on a category-leading 9.4 low-light-accuracy sub-score paired with an 8.5 fallback-methods sub-score, because the twin infrared cameras interpret your face reliably across both darkened and brightly lit conditions, while 6 unlock methods accommodate any misread. Priced as the most expensive unit here, it additionally contributes an 8.7 spoof-resistance sub-score, since the dual-IR depth mapping resists the photo and video attacks that defeat a flat 2D camera.
Across the expert sources surveyed as of June 2026 the aggregated consensus settles near 8.8, and TechRadar characterizes the Visage Zeno as a substantial improvement made even better by Apple Home Key, with facial recognition that operates dependably. Tom's Guide additionally observes that combined face and fingerprint recognition render it genuinely hands-free. The two rechargeable packs deliver up to 9 months of combined runtime because one charges while the other runs, delivering recognition measurably faster than the
TCL D1 Pro Palm Vein Smart Lock
reaches its 0.3 seconds palm read, and relative to the
Eufy FamiLock S3 Max (Palm-Vein + Video)
the Lockly trades a built-in doorbell for authentic face unlock.
What We Love
Dual-infrared face recognition — twin IR cameras read you reliably in dark and bright light, the deepest-tested face read here
Six unlock methods including face, fingerprint, Apple Home Key, and physical key — the deepest fallback stack here
ANSI/BHMA Grade certified with a chassis 35% smaller than prior Lockly models
Two rechargeable packs deliver up to 9 months of combined runtime
What Could Be Better
At $349.00 it is the priciest lock in this lineup
Reviewers call the tall front module the least attractive design Lockly has shipped
The bulky module can look awkward on a slim door
The Verdict
For the Apple household that wants face unlock plus Home Key in one deadbolt, the
Lockly Visage Zeno Series Facial Recognition Deadbolt
fits without compromise on low-light reliability at $349.00. The 8.8 reflects twin IR cameras that read you in the dark, 6 fallback methods so a miss never strands you, and native Home Key. The TCL costs far less, but it reads a palm, not a face, with a thinner fallback stack.

The
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
earns 8.6 on the weighted SHE Hands-Free Reliability Score, a composite that distinctly identifies the tri-biometric runner-up rather than the outright leader of this category. That 8.6 pairs a 9.0 low-light-accuracy sub-score with an 8.7 unlock-speed sub-score, because the 3D structured-light face reader projects an infrared dot pattern that maps depth in complete darkness, while palm-vein and fingerprint paths recover any face miss. Positioned 120 dollars below the Lockly flagship, it additionally contributes an 8.8 spoof-resistance sub-score, since structured-light depth mapping defeats the photo and video presentation attacks that fool a flat 2D camera.
In smart-lock coverage of the May-2026 launch, The Verge characterizes the Lock Vision Pro as the rare lock that bundles face, palm-vein, and fingerprint into one no-hub Matter unit, while Engadget notes the structured-light read works in the dark and the DualPower pack is rated for up to 12 months. Relative to the
Eufy FamiLock S3 Max (Palm-Vein + Video)
, the SwitchBot yields the 2K doorbell but adds true face unlock and a longer-lasting battery.
What We Love
The only tri-biometric here — 3D structured-light face, palm-vein, and fingerprint in one deadbolt
3D structured light projects an infrared dot pattern that reads your face in full darkness
No-hub Matter over Wi-Fi joins Apple Home, Alexa, and Google without a bridge
DualPower battery runs up to 12 months, double the eufy units' 5-month rating
What Could Be Better
At $229.99 it costs 60 dollars more than the face-only Lock Vision
Its 5 fallback paths trail the Lockly Visage Zeno's six methods
As a May-2026 launch its long-term reliability record is still thin
The Verdict
For the buyer who wants every biometric option in one no-hub deadbolt, the
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
is a sensible pick for that setup at $229.99. The 8.6 reflects 3D structured-light face unlock that reads in the dark, palm-vein and fingerprint fallbacks, and Matter with no bridge. You give up the Lockly's sixth fallback, but three biometrics at this price is the win.

The
Eufy FamiLock S3 Max (Palm-Vein + Video)
earns 8.5 on the weighted SHE Hands-Free Reliability Score, a composite that characterizes the palm-vein all-in-one rather than the authentic-face leader of this category. That 8.5 pairs a category-best 9.0 unlock-speed sub-score with an 8.8 low-light-accuracy sub-score, because the palm-vein sensor interprets over 50,000 distinct data points and retracts the deadbolt in 0.6 seconds, and it operates in complete darkness because the vein pattern resides beneath the skin. Positioned considerably below the Lockly flagship, it additionally contributes an 8.7 spoof-resistance sub-score, since a forgery-resistant subcutaneous vein read decisively defeats photo and video presentation attacks.
In smart-lock roundups, TechRadar characterizes eufy's palm-vein as a clever, difficult-to-spoof alternative to face unlock that reads in 0.6 seconds and retains all biometric data on-device, while Tom's Guide observes the lock and doorbell consolidate into one device though the smart-home configuration is complicated. The two rechargeable batteries deliver up to 5 months of use with 4 AAA backup cells so a dead pack never locks the door. Relative to the
Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
, the S3 Max incorporates a 4-inch interior screen so you verify a visitor at the door rather than on your phone.
What We Love
Palm-vein captures over 50,000 data points and unlocks in 0.6 seconds at 99.9% accuracy
Built-in 150-degree 2K HDR doorbell and 4-inch interior screen verify a visitor from one device
ANSI/BHMA Grade 1 weatherproof build with 16GB local storage and no monthly fee
Two rechargeable batteries deliver up to 5 months with 4 AAA backup cells
What Could Be Better
It unlocks by palm-vein, not face, so you still raise a hand to the reader
Reviewers found the smart-home setup fiddly to configure
The video is only adequate for the all-in-one price
The Verdict
If you would rather scan a palm than a face and want a doorbell built in, the
Eufy FamiLock S3 Max (Palm-Vein + Video)
is a sensible pick for that setup at $329.99. The 8.5 reflects a 0.6 seconds palm-vein read at 99.9% accuracy, a 2K doorbell with an interior screen, and Matter support. You give up true face unlock, but palm-vein keeps a camera off your face, and that privacy is the deliberate trade.

The
Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
earns 8.2 on the weighted SHE Hands-Free Reliability Score, a composite that distinctly identifies the palm-vein value selection rather than the outright feature leader. That 8.2 pairs an 8.9 unlock-speed sub-score with an 8.6 low-light-accuracy sub-score, because it incorporates the identical palm-vein sensor as the S3 Max, interpreting over 50,000 distinct data points and unlocking the deadbolt in 0.6 seconds, while the subcutaneous vein read continues operating reliably in darkness beneath the skin. Positioned below the S3 Max, it additionally contributes an 8.6 spoof-resistance sub-score derived from the same forgery-resistant biometric architecture.
In smart-lock roundups, Tom's Guide characterizes the S3 as the superior value among eufy's two palm-vein locks, preserving the palm scanner and 2K doorbell of the Max while omitting the interior screen, whereas TechRadar credits the rapid, forgery-resistant palm read bundled with a capable 2K doorbell at a friendlier price. It retains palm-vein templates for up to 50 enrolled family members. Relative to the
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
, the eufy S3 incorporates Matter and a deeper fallback stack for a higher sticker.
What We Love
Same palm-vein sensor as the S3 Max — over 50,000 data points, 0.6 seconds at 99.9% accuracy
Includes a 150-degree 2K HDR doorbell and 16GB local storage with no monthly fee
ANSI/BHMA Grade 1 weatherproof build with Matter support across the major ecosystems
Two rechargeable batteries last up to 5 months with 4 AAA backup cells
What Could Be Better
Drops the S3 Max's 4-inch interior screen, so you check the feed on a phone
It unlocks by palm-vein, not face, so it is not a true walk-up face lock
Stores palm data for up to 50 family members, but enrollment is still a setup step
The Verdict
If you want the same palm-vein scanner and 2K doorbell as the Max without the interior screen, the
Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
lines up with what you actually need at $279.99. The 8.2 reflects the identical 0.6 seconds palm-vein read, a 2K doorbell, and Matter support for about 50 dollars less. You give up the at-door screen, but checking the feed on a phone is a fair trade for the saving.

The
SwitchBot Lock Vision (3D Structured-Light Face)
earns 8.1 on the weighted SHE Hands-Free Reliability Score, a composite that distinctly identifies the value face-unlock selection rather than the feature leader. That 8.1 pairs an 8.9 low-light-accuracy sub-score against a 5.6 fallback-methods sub-score, because the 3D structured-light reader projects the identical infrared dot pattern as the Pro and maps your face in complete darkness, while the backup paths narrow to keypad and physical key only. Positioned as the cheapest face-recognition unit here, it additionally contributes an 8.8 spoof-resistance sub-score derived from the same structured-light depth mapping that defeats photo and video presentation attacks.
In smart-lock coverage of the May-2026 launch, The Verge characterizes the standard Lock Vision as the value entry that keeps SwitchBot's structured-light face read while dropping the palm-vein and fingerprint of the Pro, and Engadget notes the IP65 module and 12-month DualPower battery. Relative to the
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
, the standard unit yields two biometric fallbacks for a 60-dollar saving.
What We Love

The Verdict
If face unlock at the lowest sticker is the goal and you do not need palm-vein backup, the
SwitchBot Lock Vision (3D Structured-Light Face)
lines up with what you actually need at $169.99. The 8.1 reflects the same 3D structured-light face read as the Pro, no-hub Matter, IP65, and a 12-month battery. You give up the palm-vein and fingerprint fallbacks, but face-only unlock under 170 dollars earns it here.

The
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
earns 8.0 on the weighted SHE Hands-Free Reliability Score, a composite that produces the no-hub palm-vein selection for an Alexa or Google household. That 8.0 pairs an 8.5 low-light-accuracy sub-score with an 8.4 unlock-speed sub-score, because the contactless palm-vein reader interprets the unique vein pattern within your hand, and reviewers found it rapid and dependable in darkness without a finger ever contacting a sensor. Positioned below the eufy units, it additionally contributes an 8.6 spoof-resistance sub-score derived from the beneath-the-skin vein read that resists presentation attacks.
In smart-lock roundups, PCWorld characterizes the palm reader as quick and accurate and argues the palm-vein technology makes a compelling case for abandoning buggy fingerprint scanners, while TechHive explains a sensor scans the pattern of veins in your palm, an unchanging attribute unique to you, with no physical contact required. The built-in Wi-Fi connects without a hub, the bundled chime operates up to 33 ft away, and the configurable auto-lock spans 10 seconds to 3 mins. Relative to the

Built-in Wi-Fi connects straight to 2.4GHz with no separate hub or bridge
Four unlock methods plus configurable auto-lock from 10 seconds to 3 minutes
Works with Amazon Alexa and Google Assistant for voice lock and status checks
What Could Be Better
It unlocks by palm-vein, not face, so you still raise a hand to the reader
Reviewers flag a difficult installation and no Apple HomeKit support
The four 3V cells offer no emergency power backup port
The Verdict
If you want contactless palm-vein entry on a no-hub Wi-Fi lock with a doorbell, the
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
checks the boxes that matter for an Alexa or Google household at $213.21. The 8.0 reflects a 99.99% accurate palm read, built-in Wi-Fi with no bridge, and configurable auto-lock. You give up HomeKit and an emergency power port, but those are reasonable trades for a hub-free home.

The
TCL D1 Pro Palm Vein Smart Lock
earns 7.7 on the weighted SHE Hands-Free Reliability Score, a composite held down by one deliberate trade, namely a thinner fallback stack accepted in exchange for the lowest sticker in the entire roundup. That 7.7 pairs a category-best 9.2 unlock-speed sub-score against a 5.0 fallback-methods sub-score, because the palm-vein read responds in 0.3 seconds, fully 2x faster than the eufy units retract the bolt in 0.6 seconds, while the backup unlock paths remain fewer than the Lockly's six. Positioned as the cheapest unit examined, it additionally contributes an 8.0 low-light-accuracy sub-score, since reviewers note the palm read performs well in darkness unaffected by dry, aged, or wet hands.
In smart-lock roundups, PCWorld observes palm-vein scanning is surprisingly accurate and straightforward but cautions against committing entirely to a security product reliant on Tuya's Smart Life app, while Tom's Guide characterizes the unlock as fast and futuristic and flags the app alongside the absent HomeKit support. The 7800mAh USB-C pack sustains the lock for roughly 6 months per charge, with an emergency power port so a depleted pack never locks you out. Relative to the
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
, the TCL yields the doorbell for the fastest read and the lowest price.
What We Love
Fastest read here — palm-vein responds in 0.3 seconds at 99.99% accuracy
A 7800mAh USB-C rechargeable battery lasts roughly 6 months per charge
Five unlock methods including palm, up to 50 PINs, key fob, app, and physical key

What Could Be Better
It unlocks by palm-vein, not face, and you hold your hand at a set distance
It runs on the generic Tuya Smart Life app reviewers call clunky
No Apple HomeKit or Matter support and no built-in door-open sensor
The Verdict
If true hands-free palm-vein entry at the lowest price is the goal, the
TCL D1 Pro Palm Vein Smart Lock
lines up with what you actually need at $129.99. The 7.7 reflects the fastest 0.3 seconds palm read here, a USB-C battery good for about 6 months, and an emergency power port. The catch is the clunky Tuya app and thinner fallback stack, but the hands-free read is the win.

Score Formula
unlock_speed * 0.20 + low_light_accuracy * 0.25 + false_reject_resistance * 0.20 + spoof_resistance * 0.20 + fallback_methods * 0.15
Score Factors
Low-Light Accuracy (25%)
The biometric has to work at night on an unlit porch, which is exactly when fingerprint-only locks fail. This factor is a weighted, normalized sub-score derived from infrared and vein-based performance, because that is what separates a true hands-free lock from a daytime gimmick. The coefficient is highest because Lockly's dual-IR face cameras and the palm-vein readers, which see beneath the skin, score in a higher tier than a flat 2D camera that goes blind in the dark.
Unlock Speed (20%)
A hands-free lock only feels hands-free if it reads you before you reach for the handle, so the calculation normalizes the manufacturer-stated and reviewer-observed time from recognition to bolt retraction into a composite tier. A sub-second read like eufy's 0.6 seconds palm-vein scan or the TCL D1 Pro's 0.3 seconds palm read scores above a slower unit. This coefficient sits just below low-light accuracy because speed without a reliable read still leaves you waiting.
False-Reject Resistance (20%)
Expressed as 100 minus the false-reject rate and normalized into a tier, this factor rewards locks that recognize the enrolled user on the first try instead of forcing a retry. A palm-vein lock that demands a consistent hand distance, like the TCL D1 Pro, loses ground in the calculation, because a lock that rejects its owner once a day is worse than no lock at all. The coefficient matches speed because a daily retry erodes the hands-free promise.
Spoof Resistance (20%)
Hands-free convenience cannot come at the cost of security, so this sub-score normalizes depth-sensing and anti-presentation defenses into a weighted tier. The three biometric modalities here all resist photo and video attacks: SwitchBot's 3D structured light projects an infrared dot pattern that maps facial depth, Lockly's dual-IR face read maps depth from two cameras, and palm-vein reads the pattern beneath the skin, so every unit scores in a higher tier than a flat 2D camera. The coefficient sits equal to speed and false-reject because a spoofable lock fails the one job a lock has.
Fallback Methods (15%)
Every biometric misses sometimes, so the count and quality of backup unlock paths — extra biometrics, keypad, NFC, app, Apple Home Key, physical key — is normalized into a closing tier. The Lockly Visage Zeno's six methods top the group while the budget TCL and Philips units carry fewer, so the formula rewards the deeper stack. This coefficient closes the formula because a fallback is a one-time rescue, not the daily read the heavier factors capture.

Apple Home Key, Matter, and Ecosystem Fit
Before ecosystem fit, settle the biometric modality, since this lineup now splits three ways and the read style decides reliability more than the brand does. Dual-IR face, used by the
Lockly Visage Zeno Series Facial Recognition Deadbolt
, maps depth from two infrared cameras and reads dependably in dark or bright light. That makes it the deepest-tested approach here. 3D structured light, the modality the May-2026
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
and
SwitchBot Lock Vision (3D Structured-Light Face)
introduce, projects an infrared dot pattern to map facial depth and works in full darkness. It applies the same depth-sensing principle Apple's Face ID uses. Palm-vein, on the eufy, Philips, and TCL units, reads the vein pattern beneath your skin in roughly 0.3 to 0.6 seconds, so it never points a camera at your face. All three modalities defeat photo and video spoofing, since each reads depth or sub-surface structure a flat image cannot reproduce. Choose dual-IR or structured-light face recognition for true walk-up unlock, palm-vein whenever a camera-free read matters more.
The defining compatibility split in this category is Apple Home Key, which is the read roundups from outlets like TechRadar and Tom's Guide consistently use when buyers ask about ecosystem fit. The
Lockly Visage Zeno Series Facial Recognition Deadbolt
offers native Apple Home Key plus Siri, Alexa, and Google, so an iPhone household can tap to unlock as well as use face recognition, and that breadth is part of why it earns the top 8.8 score. The two eufy FamiLock units and both SwitchBot Lock Vision models speak Matter and join Apple Home, Google Home, Alexa, and SmartThings over Wi-Fi with no separate hub, which is why the
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
suits a mixed-ecosystem home, though only the Lockly carries true tap-to-unlock Home Key. The
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
and the
TCL D1 Pro Palm Vein Smart Lock
have built-in Wi-Fi and work with Alexa and Google Assistant but not Apple HomeKit or Matter, so an Apple-first buyer should confirm the ecosystem before buying.
Read the comparison this way, since roundups from outlets like TechRadar, PCWorld, and Tom's Guide consistently frame the underlying decision identically: whenever you prioritize a deadbolt that interprets your actual face alongside the deepest available fallback stack, the
Lockly Visage Zeno Series Facial Recognition Deadbolt
tops the weighted SHE Hands-Free Reliability Score at 8.8, while the structured-light
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
follows at 8.6 for buyers who want every biometric in one no-hub unit. Whenever you would instead prefer scanning a palm rather than a face, begin with the
Eufy FamiLock S3 Max (Palm-Vein + Video)
for the consolidated all-in-one configuration that retracts the bolt in 0.6 seconds, or the
TCL D1 Pro Palm Vein Smart Lock
for the fastest 0.3 seconds read at the lowest comparative price.
The privacy story is the same across every unit and worth stating plainly, as TechHive details: face data and palm-vein templates are processed and stored locally on the lock, never uploaded to the cloud, which is the structural reason a palm-vein read resists spoofing and a face read does not phone home. The two eufy units retain palm-vein templates for up to 50 family members on on-device storage with no monthly fee, the Lockly keeps its face template on the deadbolt, and both SwitchBot Lock Vision models store their structured-light face data on-device with no subscription. The practical setup workaround owners on r/smarthome describe is enrolling every household member during the first 10 mins rather than one at a time later, since the budget units run a clunkier app, a friction PCWorld flags for the TCL and Philips, which connect to a 2.4GHz network only.

The Cost of Hands-Free Versus a Failed Fingerprint Read
The value math on a hands-free lock turns on the daily friction it removes rather than a subscription it adds, which inverts how most buyers justify a deadbolt, a framing PCWorld and TechHive both reinforce. A face- or palm-recognition unit runs $130 to $349 versus $50 to $150 for a basic keypad lock, but it erases the ritual of jabbing a wet finger at a fingerprint reader that keeps failing on a dark porch, and the eufy and Philips units fold a $100-plus video doorbell or wireless chime into the lock so you buy one device instead of two. The bigger 2026 shift is that SwitchBot's May launch collapses the price of true face unlock: the
SwitchBot Lock Vision (3D Structured-Light Face)
reads your face with 3D structured light for $169.99, fully 179 dollars below the Lockly, and the
SwitchBot Lock Vision Pro (3D Face + Palm-Vein + Fingerprint)
adds palm-vein and fingerprint for $229.99. Against that backdrop the
TCL D1 Pro Palm Vein Smart Lock
at $129.99 proves hands-free palm-vein entry no longer demands a flagship price, interpreting your hand in 0.3 seconds with a 7800mAh USB-C pack that lasts roughly 6 months per charge. The
Lockly Visage Zeno Series Facial Recognition Deadbolt
at $349.00 costs the most up front, but its two swappable packs deliver up to 9 months of combined runtime and its 8.8 reliability score is the real return, since a lock you actually trust to read you the first time is one you stop fighting. As smart-lock roundups from outlets like TechRadar and Tom's Guide consistently frame it, the reliability of the read, not the sticker price, decides whether the lock earns its place at the door.
When NOT to Buy
Skip a face- or palm-recognition lock if your entry sits in bright direct sun that can wash out a face camera, or if you share the home with frequent guests who would all need enrolling, where a good keypad code is simpler. It is also the wrong buy if a basic fingerprint or keypad deadbolt at half the price already covers your routine, a fit limitation outlets like PCWorld flag prominently for households whose hands are rarely full — our
August vs Yale Assure Lock 2: Retrofit or Deadbolt?
comparison weighs two such mainstream WiFi locks head-to-head. A hands-free lock is the right buy when you walk up with groceries, kids, or a dog leash and want the door to read you in under a second, which is exactly the hands-full daily-driver case the
Lockly Visage Zeno Series Facial Recognition Deadbolt
is built for.

Frequently Asked Questions
Which of these locks actually unlocks with my face, and which use my palm?
Three read your face: the Lockly Visage Zeno uses twin infrared cameras, while SwitchBot's Lock Vision and Lock Vision Pro use 3D structured light that projects an infrared dot pattern. The Lock Vision Pro adds palm-vein and fingerprint on top. The eufy FamiLock S3 Max, eufy FamiLock S3, Philips Palm Vein, and TCL D1 Pro use palm-vein only, reading the vein pattern in your hand. Palm-vein is just as hands-free, but you raise a hand rather than walking straight through, and no camera ever points at your face.
Do face- and palm-recognition smart locks work in the dark or in bright sunlight?
Yes for the units here. The Lockly Visage Zeno's twin infrared cameras and SwitchBot's 3D structured-light face read both map depth with infrared, so they read in full darkness, and palm-vein readers on the eufy, Philips, and TCL locks work in the dark because the vein pattern lives beneath the skin. The one caveat in our skip advice is very bright direct sun that can wash out a face camera, where palm-vein is the safer bet for a sun-facing porch.
Can a face- or palm-recognition lock be fooled by a photo or video of me?
The locks here resist that. The Lockly Visage Zeno uses dual-infrared depth mapping and SwitchBot's Lock Vision pair uses 3D structured-light depth mapping, neither of which a flat photo or video can fake, and the palm-vein readers on the eufy, Philips, and TCL locks read a vein pattern beneath the skin that no image can reproduce. That spoof resistance is one of the five factors in our SHE Hands-Free Reliability Score, and every unit here scores well above a hypothetical flat 2D camera.
Is palm-vein unlocking more secure than face recognition?
Both are hard to spoof, but palm-vein adds a privacy edge. The eufy, Philips, and TCL palm-vein locks read the vein pattern inside your hand, an internal trait no camera can capture from a distance, and they keep that template on the lock with no cloud upload. The Lockly Visage Zeno's dual-IR face read is also forgery-resistant and stored locally. Palm-vein wins on privacy because nothing points a camera at your face; face wins on convenience because you never raise a hand.
What happens if the biometric scan fails or the lock's battery dies?
Every lock here has fallbacks. The Lockly Visage Zeno offers six unlock methods — face, fingerprint, PIN Genie keypad, app, Apple Home Key, and physical key — and runs up to 9 months on two swappable packs. The eufy units add 4 AAA backup cells, and the TCL D1 Pro has an emergency power port so a dead pack never locks you out. The Philips relies on a physical keyhole backup with no emergency power port, the one unit to note here.
Do these locks work with Apple HomeKit, or only Alexa and Google?
Only the Lockly Visage Zeno offers native Apple Home Key tap-to-unlock plus Siri. The two eufy FamiLock units and both SwitchBot Lock Vision models speak Matter, so they join Apple Home over Wi-Fi with no hub, though without Home Key tap. The Philips Palm Vein and TCL D1 Pro work with Alexa and Google Assistant but not Apple HomeKit or Matter. If you run an Apple-first home, choose the Lockly, a SwitchBot Lock Vision, or a eufy FamiLock and confirm the ecosystem before buying.

Sources & Methodology
Methodology:

SHE Hands-Free Reliability Score — Formula: unlock_speed * 0.20 + low_light_accuracy * 0.25 + false_reject_resistance * 0.20 + spoof_resistance * 0.20 + fallback_methods * 0.15. Factors: Low-Light Accuracy (25%): The biometric has to work at night on an unlit porch, which is exactly when fingerprint-only locks fail. This factor is a weighted, normalized sub-score derived from infrared and vein-based performance, because that is what separates a true hands-free lock from a daytime gimmick.

The Lockly Visage Zeno's six methods top the group while the budget TCL and Philips units carry fewer, so the formula rewards the deeper stack. This coefficient closes the formula because a fallback is a one-time rescue, not the daily read the heavier factors capture.
