Eight batteries, double the signal, and a matte black body rated for full weather exposure.

Here is the one for hosts and landlords who never want to hear a low-battery complaint. Where the VE017G above ships with an external gateway, this VE027 puts Wi-Fi inside the lock itself and pairs straight to a 2.4GHz network, so there is nothing extra to plug in. It runs on eight AA batteries instead of the usual four, and the maker states this delivers double signal strength, up to 95% more stable connectivity, and 98% longer battery life than standard four-battery Wi-Fi locks. The IP65 rating is the highest weatherproofing in this roundup, and BHMA and ANSI Grade 3 certification sits underneath it.

Functionality is the aspect that stands out most in owner feedback — it is mentioned more than any other trait by a wide margin — and the depth of the feature set backs that up. Seven ways to open up, an AI self-learning fingerprint sensor reading in 0.2 seconds at a stated 99.8% accuracy, and 20+ stored prints handled through the app. The code vault is generous too: 100+ codes created or deleted remotely across four types covering permanent, recurring, scheduled, and unlimited one-time use. Privacy-minded owners get AES local encryption storing logs and user data on the lock chip itself, plus anti-peep code entry and a three-minute lockout after ten wrong attempts.

The honest gap is a door-position sensor. This lock does not know whether the door is actually shut, so the bolt can extend against an open door and report “locked” when the frame is empty. A magnetic or hall sensor is the workaround some owners rig themselves, and it is the single improvement the details call out. Pair it with lithium batteries rather than standard alkaline, as owners who have run it a while advise, because the eight-battery design behaves noticeably better on them. The matte black finish is also a visual step up from standard nickel hardware on a modern front door.

The lock that skips the internet on purpose and still refuses to hand you a key.

Everything here is deliberate about what it leaves out. No Wi-Fi, no app, no fingerprints — just a keypad and a bolt. On paper that looks like a step backward, but the trade works in its favor: because the lock never reconnects to a network, the batteries last longer. Four AA alkaline cells power it for at least 12 months, and the reduced feature set is exactly why. The build is BHMA Grade 2 certified, which the maker states is stronger than a Grade 3 set, so it stands up to more force. The SmartKey system lets you re-key the lock yourself in seconds to any KW1 key after a move or a lost key, saving you a locksmith call. Hardware is treated with Microban (an antimicrobial coating), which the manufacturer says delivers a surface 99.9% cleaner than an untreated one.

Code management is where this punches above its weight. You get 50 user codes, 10 one-time codes for guests or cleaners, and one programming code to edit or delete them. Auto-lock is configurable at 30 seconds, 1 minute, 3, 5, or 10 minutes, and the intrusion alert sounds an alarm and freezes the keypad for a minute after three wrong entries. Flip on Vacation Mode and the keypad goes dark entirely while you are away. Buyers who wanted a no-nonsense lock report it feels like high-end hardware with no phone setup required.

The honest limits: there is no Wi-Fi, so nothing here gives you remote open up, notifications, or a log of who came through, and that is by design rather than a defect. If you want to open up for a delivery driver from your office, this lock has no remote access. Owners do flag one physical quirk — the battery cover can sit loose and rattle when the door shuts, which is a fit concern rather than an electrical one. For houses with multiple entry doors where you just want to stop juggling keysets, this is the straightforward answer.

A talking keypad walks you through setup, then a fingerprint gets you in for good.

For a first-time smart deadbolt buyer who dreads a manual full of small print, this is the friendliest on-ramp. The lock speaks its setup steps out loud in English, French, or Spanish, so you can program it standing at the door without holding a guide. The fingerprint scanner reads in 0.3 seconds with a stated accuracy rate of up to 99.99%, so you get in almost instantly. There is one honest caveat straight from the manufacturer: recognition may be less effective for children under 6 and adults over 65, so keep fingers clean and dry. What makes the fingerprint attractive is how often it works for people whose prints never register on other readers — one buyer notes their finger “never registers on anything,” yet this pad reads it fine.

The code side is built for hospitality. You get unlimited one-time PIN codes, so you can hand a delivery person or a housecleaner a single-use pass that evaporates the moment it is used. Auto-lock is adjustable from 30 to 180 seconds, and a one-touch lock engages instantly if you press and hold any keypad number for two seconds. Note that the lock cannot detect whether the door is actually closed — the bolt will extend against an open door — and auto-lock ships disabled, so you must switch it on in the settings. It takes 1.5V AA alkaline batteries, and the maker explicitly warns against rechargeable and carbon types, which can stop the lock from powering on.

The profile here is intentionally offline. There are no connection protocols at all, so no Wi-Fi, no app to fight, and nothing phoning home — which is exactly what some owners want from their front door. Installation runs with a screwdriver and fits doors 1-3/8 inches to 1-3/4 inches thick, with a recommendation to check your door type before buying. The wire management is the fiddly part; owners mention the connector cable being long and tricky to tuck under the cover. Two keys and an adjustable latch come in the box.

One box replaces the deadbolt and both door handles, which landlords will appreciate.

What makes this different from the other Veise locks in this roundup is that it does not stop at the deadbolt. The set includes two lever handles to match, so a tired entry door gets a full refresh in one purchase rather than two. It is built in solid zinc alloy with IP54 weatherproofing and a BHMA and ANSI Grade 3 certification, with an expected lifespan exceeding 10 years from the maker. open up options run wide: app, codes, web portal, IC cards with 1,000+ capacity, e-keys, authorized admin, physical key, and Apple Watch. Auto-lock adjusts across a huge range from 5 to 900 seconds, and a # hold for two seconds locks instantly.

For someone running a rental, the management tools are the point. The DDlock app and web portal let you change tenant access in minutes without a locksmith, remotely generate and share passcodes, set e-keys with user permissions, and pull the access log. Codes run 250+ deep across permanent, scheduled, recurring, one-time, and erasable types, each deleteable remotely. Privacy Mode, Silent Mode, and Passage Mode cover the day-to-day — quiet late entry, undisturbed evenings, and free-swinging during a move or party. All lock data is stored locally with AES encryption. The catch on remote features is the G2 gateway needed for Wi-Fi, which is sold separately, so budget for that if you want to control this lock from offsite.

One pattern keeps showing up in owner feedback: the printed instructions are weak, and the phone support saves the install. Multiple buyers describe calling in when the manual left them stuck — one notes that without the rep walking them through, they would have returned the lock. The keys and code cards that ship in the box are also a nice touch for guests; the IC card system lets you hand a sitter a physical fob rather than sharing a code. A professional install is worth considering if you are not handy with door hardware, and the app-run setup makes code changes a phone job once it is on the door.

If you already own a eufy doorbell, this is the deadbolt that finishes the set.

Owners who have eufy cameras running already get the best of this lock: it joins the same app, so your doorbell and your deadbolt share one screen and one routine. The lock skips the bridge and connects straight to Wi-Fi, so remote control and event notifications work from anywhere without extra hardware. Eight AA batteries in the box drive around eight months of use, and the battery level shows in the app so you are not caught mid-week with a dead lock. It is BHMA Grade 3 certified after being locked and open up more than 100,000 times, and it keeps working through a wide temperature range while carrying an IP53 water-resistance rating.

The fingerprint sensor is self-learning, which means each touch teaches it your print a little better, so accuracy improves over the first weeks instead of degrading. Installation is 15 minutes with no drilling on most standard deadbolts, and it fits bores under 54mm just by removing the spacer. The deadbolt will also fire an alarm on an unusual attempt to open the door, which is a nice safety net.

Two honest limits to weigh. First, there is no dedicated lock button on the exterior, so if you want to lock without pulling out a phone you will do it with a fingerprint or on the keypad. Second, the fingerprint reader carries mixed feedback among owners — the majority find it smooth and fast, and a smaller set run into inconsistency with cold or damp fingers. With an eufy doorbell or camera, the shared app adds real value; without one, the lock works fine but you lose that ecosystem bonus.

Thread-powered battery life that runs 18 months, with Apple Home support for the smart home crowd.

If you live inside Apple Home or a Matter ecosystem (a smart-home standard that lets devices talk to each other), this is the deadbolt that speaks the native language. Thread’s low-energy mesh network (a wireless system where devices relay signals to each other) is why the battery stretches to 18 months rather than the eight or twelve months you see on standard Wi-Fi locks in this roundup, and the mesh self-heals by rerouting around a device that drops offline. Seven open up methods are covered: fingerprint ID storing up to 50 prints, 50 passcodes, the ULTRALOQ app on iOS and Android, a web portal, eKey and code sharing, voice through Siri, Alexa or Google, and two mechanical keys. An AI-driven fingerprint scanner and a glove-friendly, fingerprint-resistant keypad round out the hardware.

App control runs over built-in Wi-Fi so you can lock, open up, share permanent or temporary eKeys, and see activity history without a hub, and a self-healing mesh helps keep the connection steady. Keep your router within 70 feet of the lock, per the manufacturer, and note that the Wi-Fi radio only speaks 2.4 GHz. The optional Matter over Thread route needs a compatible Thread Border Router to work, so this is a lock that rewards buyers with an existing smart home hub and frustrates buyers hoping to skip one. Rated ANSI BHMA certified with zinc alloy construction and IP65 weather resistance, this is one of the few in this roundup that goes all-in on the protocol side.

The honesty is necessary here because owner feedback waves in more than one direction. Functionality and installation both land solidly positive. The fingerprint reader and auto-open up features carry mixed reviews — some owners find them flawless, others hit inconsistency and occasional Bluetooth drops. Connectivity draws the loudest skepticism: customers note trouble connecting to Wi-Fi and HomeKit, and a few mention battery drain when the lock is constantly trying to reach the network. This is a lock for someone who wants native Matter integration and will accept the setup work that comes with it. If you want plug-and-play remote access without a Thread Border Router, the eufy C220 is the simpler pick.

Hover your palm. No finger pressing, no key, no code — and a backup battery when things go wrong.

Palm vein scanning is the standout here, and it solves a problem that some people never knew they had: cold, dry, or fussy fingertips that fail a sensor. The Wyze Palm Lock reads the vein pattern under your hand without requiring a touch, so you simply wave a palm and the door opens. It is not a fingerprint reader at all, so capacity counts are different from the rest of this list. It stores up to 50 guest codes for the illuminated keypad, and voice control runs through Alexa or Google. The lock can also be controlled from the live feed of a Wyze Video Doorbell if you have one, which is the natural pairing.

The mechanical choices here are smart. A 6-month main battery is backed by a 2-week secondary cell, so you have a two-week cushion before anything dies, and if both drain the integrated USB-C port takes a power bank for an emergency charge. That means you are never locked out. The lock carries IP53 weather resistance and BHMA3 certification, and a built-in gyroscope detects the door angle and movement so it locks only after the door actually shuts — no false locks against an open frame. A millimeter wave radar, the kind used in a car’s self-driving sensors, checks for a person nearby and wakes the lock only then, which is why the battery holds up better than always-on models.

A few honest notes emerge from owner use. Palm recognition is fast for most, but a small set find it hit-or-miss with the exact hand angle, and initial palm setup needs to match your real approach to the door. Charging is slow, per buyers who have timed it, though the backup battery keeps the lock functional while the main one tops up. Set-up is app-only, so you will want a phone available. Once running, users describe switching to the Super Battery Saver mode when a screen door was pressuring the sensor and draining the cell faster than a plain wood door would.
