Best Cordless Fingerprint Smart Locks by Battery Spec

The best cordless fingerprint smart lock is the eufy Security Smart Lock C220, a Wi-Fi deadbolt that runs roughly 8 months on 8 AA batteries and offers six unlock methods. If you want a rescue port instead of a spare battery drawer, the Wyze Auto-Lock Bolt v2 adds USB-C emergency power to a nearly identical 8-month claim. Get this wrong and the failure is specific: a lock that dies with no backup, on a door you're standing outside of, in the rain.

Best cordless fingerprint smart lock at a glance

How I screened these five cordless fingerprint smart lock picks

I set three criteria before looking at any listing, and weighted them in this order.

1. Battery independence, weighted heaviest. Cordless means the lock carries its own power. A published battery figure, a cell count or a recharge method had to be in the listing, not implied.
2. A named backup path, weighted second. Fingerprint sensors get wet, dirty and cold. Physical keys, a USB-C port or a keypad all count. Nothing counts more than something.
3. A published fingerprint capacity or speed figure, weighted third. It's the one biometric number these listings actually state, so it's the only one I can compare.

Those weights come from the failure mode, not from spec-sheet neatness. A lock that never gets power fails once every eight months. A lock with no backup fails permanently the first time it fails at all.

Worth saying plainly: "cordless" is only partly a real constraint here. Every one of these five runs on batteries, so nothing in the set is hardwired, but Amazon's results also crossed category lines. Two of these five are bike locks, not door locks. I've kept them because they're genuinely good at what they do, and labelled them so you don't buy a U-lock for a front door.

What actually decides a cordless fingerprint smart lock?

Most guides to the best cordless fingerprint smart lock compare unlock speed. Every listing here claims sub-second recognition. The eufy C220 says under 1 second, Wyze and Evanshow both say 0.5 seconds, and Anweller claims a fraction of a second too. When four of five products claim the same thing, that number has stopped being a differentiator.

The real deciding criterion is what happens when the battery is flat and your finger doesn't read.

That splits this field cleanly:

• eufy C220: 8 AA cells plus a physical key plus a keypad plus the app. Four fallbacks.
• Wyze Bolt v2: 8 AA cells, a USB-C port that takes any power bank, backup keys and a code.
• Evanshow knob: 2 mechanical keys and 4 IC cards, plus a keypad.
• Anweller U-lock: keys included, on a lock rated IP67.
• eLinkSmart cable: app access and a battery indicator, no key.

Second criterion: form factor, which is really a question about what you're locking. A deadbolt goes in a prepped door bore. A knob replaces a knob. A U-lock secures a frame to a rack. Nobody mounts a U-lock on a front door, but plenty of people buy one thinking they've bought a smart lock.

1. eufy Security Smart Lock C220 — Best overall

The C220 is the most complete cordless fingerprint smart lock here because it combines built-in Wi-Fi with four separate ways in when the fingerprint reader says no.

Best for: an exterior front door that needs remote control Skip it if: your door already has a knob-only bore

Six unlock methods is the headline, and eufy lists them: fingerprint, the app, the keypad, a physical key, and integration with an Apple device. That breadth matters more on a front door than on any other lock in this set, because a front door is the one you get locked out of. The Wi-Fi radio is built in, so eufy says there's no bridge to buy or plug in, which is the difference between one purchase and two.

At 4.41 x 7.67 x 4.49 in this is the bulkiest of the two deadbolts by exterior footprint, and it's the one with the taller keypad face. eufy claims around 8 months from 8 AA batteries and describes self-learning recognition that sharpens with each touch.

It's also the second-most expensive pick here, and it's the one buyers choose most often among the door locks in this group. Against the Wyze, the trade-off is real: no USB-C rescue port and no published weight figure, so you're relying on the AA drawer and the key. Two sellers list it, which is one more than any other pick here.

Pros:

• Six unlock methods, more than any pick here
• Built-in Wi-Fi with no bridge required
• 8 AA cells, around 8 months claimed
• Works with a eufy doorbell for keyless routines
• Two sellers list it

Cons:

• No USB-C emergency power port
• Bulkiest exterior footprint of the two deadbolts
• Second-highest price position in this set
• No published weight or warranty

2. Wyze Auto-Lock Bolt v2 — Best upgrade

The Bolt v2 is the only lock here with a USB-C port that turns any power bank into a door key.

Best for: anyone who wants a USB-C rescue port on a deadbolt Skip it if: you avoid app accounts entirely

That USB-C port is the single most useful spec in this whole roundup. Wyze says flat batteries no longer mean a flat door: plug in a power bank, unlock, then swap cells at your leisure. Everything else here answers a dead battery with a key you may not be carrying.

The listing adds two ratings the other locks don't publish: BHMA2 and IP53. It's a 2025 release, the newest product in this set. At 3.25 lb it's substantial, though its 1.41 x 7.09 x 2.93 in profile is slimmer front-to-back than the eufy's. Wyze claims 0.5-second fingerprint recognition, AI learning that improves over time, an anti-peep keypad, auto-lock, and unlocking straight from a Wyze Video Doorbell feed.

So why isn't it first? Breadth of fallback. eufy lists six unlock routes to Wyze's four, and only one seller stocks the Bolt v2. It also sits in the middle price position here, so it's cheaper than the C220 while giving up the ecosystem depth. If your priority is never being locked out, this is arguably the smarter buy.

Pros:

• Only pick with USB-C emergency power
• Published BHMA2 and IP53 ratings
• 0.5-second recognition claim with AI learning
• Auto-lock plus anti-peep keypad
• Newest release in the set, 2025

Cons:

• Four unlock methods, fewer than the eufy's six
• Only one seller lists it
• 3.25 lb is heavy for a retrofit deadbolt
• Doorbell unlock needs a second Wyze device

3. Evanshow Fingerprint Door Lock Biometric Door Knob with — Best budget pick

This is the cheapest pick here and the only knob-style lock, which makes it the one that fits interior doors the deadbolts can't touch.

Best for: interior bedroom, office or rental room doors Skip it if: you need phone access or remote codes

Form factor is the whole argument. Bedroom, office and storeroom doors usually have a knob bore and no deadbolt, and a C220 won't help you there. Evanshow says this fits wooden doors 1.18 to 1.97 in thick, left or right swing, with no drilling and no wiring. At 1.2 lb it's the lightest pick in this roundup by a wide margin.

The capacity figures are the strongest in the set: up to 100 fingerprints and 50 passwords, plus 2 mechanical keys and 4 IC cards. That's four access types on the cheapest product here. Evanshow claims recognition in under 0.5 seconds.

One line in the listing deserves your attention. Evanshow states you must register an administrator fingerprint before first use, because until an admin exists, any fingerprint opens the door. Do that step on day one.

The trade-offs are clear. The size field reads "None APP", so there's no phone control, no remote codes and no Wi-Fi. No battery figure is published either, which is a notable gap in a cordless lock. It sells faster than any other pick here, but it's an interior-door product wearing smart-lock clothes.

Pros:

• Cheapest pick in this set
• 100 fingerprints and 50 passwords supported
• Lightest at 1.2 lb, fits 1.18–1.97 in doors
• No drilling or wiring claimed
• Four access types including 4 IC cards

Cons:

• No app, no Wi-Fi, no remote access
• No published battery life figure
• Knob format, not a deadbolt for exterior doors
• Any fingerprint works until you set an admin

4. Anweller Fingerprint Bike U Lock with 5ft Security Steel — Best minimal setup

A 24-month standby claim and an IP67 rating make this the pick you can mount outdoors and forget about.

Best for: an e-bike, scooter or gate left outdoors Skip it if: you need a door lock

Nothing else here is built for weather like this. Anweller lists IP67 waterproof and dustproof protection, anti-rust and anti-corrosion treatment, and a protective cover over the reader. The Wyze deadbolt publishes IP53, which handles splashes. IP67 handles immersion.

The battery figure is the other reason it earns a place: a 320mAh lithium-ion cell that Anweller says gives 24 months of standby and around 4,000 unlocks per full charge. That's the longest interval any pick here claims, and it's rechargeable rather than a bag of AA cells.

Build is zinc alloy for crack resistance, and the package includes a 5ft steel cable so you can loop a wheel or a rack. It weighs 4.1 lb, the heaviest pick in this roundup, and measures 8.2 x 6.5 x 5.2 in. Keys are included as a backup, which the cable lock below can't match.

The trade-off is unavoidable and it's a big one: this is a U-lock. It secures bikes, scooters, gates and fences. It does not go on your front door. It also carries the highest price position in this set, and it's the slowest seller among the products here.

Pros:

• IP67 rating, highest weather protection here
• 24-month standby, 4,000-unlock charge claim
• Zinc alloy body with 5ft steel cable included
• Rechargeable, no AA batteries to buy
• Physical keys included as backup

Cons:

• Not a door lock in any form
• Heaviest pick at 4.1 lb
• Highest price position in this set
• No app or remote management at all

5. Cord Padlock Waterproof Fingerprint Cable Lock eLinksmart — Most versatile

A 38cm flexible cable and 1,000+ app users make this the one pick that locks things with no bore, no shackle gap and no fixed shape.

Best for: fridges, cabinets and travel bags Skip it if: you want serious theft resistance

The cable is the feature. At 38cm it wraps around French door refrigerator handles, cabinet knobs, folding bike frames, helmets and luggage. eLinkSmart notes it fits most French doors and cabinets except those with very wide handles. If you're child-proofing a fridge or locking a cupboard, no deadbolt or U-lock in this set can help.

Access management is unexpectedly deep for the second-cheapest pick here. eLinkSmart lists 20 fingerprint users plus 1,000+ app users, with an admin able to set unlock windows and schedules and review access history. That's the only scheduling feature in this entire roundup. The steel cable sits inside PVC rubber for rust resistance, and there's a battery indicator with USB-C charging.

At 0.95 x 6.3 x 3.5 in it's the smallest body here, which is why it travels well.

The honest limits: a flexible cable is inherently easier to defeat than a zinc alloy U-lock or a deadbolt, no battery duration figure is published beyond a low-consumption claim, and there's no physical key backup. It's also the slowest-selling pick in the set by a wide margin.

Pros:

• 38cm cable fits fridges, cabinets and frames
• 20 fingerprint users plus 1,000+ app users
• Only pick with scheduled access and access logs
• USB-C charging with battery indicator
• Smallest body here for travel

Cons:

• Cable offers less resistance than a U-lock
• No physical key backup at all
• No published battery duration figure
• Slowest seller of the five

Deadbolt, knob, U-lock or cable: which shape fits your door?

This is the question the search results blur, so check your door before you check anything else.

• A prepped exterior door with a deadbolt bore. The eufy C220 or the Wyze Bolt v2. Both are deadbolt replacements and both carry keypads and keys.
• An interior door with a knob and no deadbolt. Evanshow, and only Evanshow. It's the sole knob-format pick, sized for wooden doors 1.18 to 1.97 in thick.
• A metal door, a fire door or a door thinner than 1.18 in. None of these five publish a fit spec for that, so measure and check the listing yourself.
• A bike, scooter, gate or fence. Anweller, for the IP67 rating and the 5ft cable.
• A fridge, cabinet, bag or helmet. eLinkSmart, for the 38cm flexible cable.

The threshold that matters most: 1.18 in. Below that door thickness, the Evanshow knob is out of spec, and neither deadbolt publishes a compatibility range at all.

How long does the battery really last?

The published figures split into two camps, and they aren't directly comparable.

AA-powered deadbolts. eufy and Wyze both claim about 8 months from 8 AA batteries. That's 16 cells a year between the two of them if you run both. Wyze includes the 8 cells in the box and adds the USB-C port, which is the difference between an inconvenience and a lockout.

Rechargeable locks. Anweller states a 320mAh cell with 24-month standby and roughly 4,000 unlocks per charge. eLinkSmart states USB-C charging, a battery indicator and low power consumption, without a duration figure.

Two practical notes. First, standby is not use: 4,000 unlocks at ten a day is a little over a year, not two. Second, Evanshow publishes no battery figure whatsoever, which for a cordless lock is the gap I'd want closed before buying. Its keypad and 2 mechanical keys cover you regardless.

If you hate maintenance, the rechargeable pair win. If you hate charging cables, buy AA cells in bulk and set a calendar reminder for month seven.

What the listings do not tell you

Five gaps worth knowing about before you order.

Warranty. Not one of these five listings publishes a warranty term. Check the manufacturer's own page before you commit.

Certification, mostly. Only Wyze publishes a security grade, BHMA2. The other four say nothing about a graded standard, including the two premium-priced picks.

Weather sealing on the deadbolts. Wyze states IP53. eufy publishes no ingress rating, so a fully exposed door in driving rain is an unknown quantity.

Fingerprint capacity on the deadbolts. Evanshow says 100 prints. eLinkSmart says 20 prints plus 1,000+ app users. eufy and Wyze list unlock methods but no user ceiling.

Weight, on the eufy. The C220 lists dimensions but no weight figure, which makes it the only pick here you can't compare on that axis.

The pattern: the cheaper picks publish more capacity numbers, and the deadbolts publish more integration features. Neither group publishes warranties.

The verdict

Split this by what you're willing to spend, because the tiers buy genuinely different things.

The entry tier buys you access control without a phone. Evanshow, the cheapest pick here, hands you 100 fingerprints, 50 passwords, 4 IC cards and 2 keys on an interior door knob, with no app and no Wi-Fi. eLinkSmart, the second-cheapest, buys flexibility instead: a 38cm cable, scheduled access windows and an access log. Both are complete products at their price. Neither is a front-door lock.

The middle tier is where the best cordless fingerprint smart lock argument gets serious. The Wyze Auto-Lock Bolt v2 sits alone there, and it publishes what nothing else does: BHMA2, IP53, a 0.5-second recognition claim, auto-lock, and a USB-C port that a power bank can revive.

The premium tier buys ecosystem or weather. The eufy C220 wins overall on breadth, six unlock methods and built-in Wi-Fi with no bridge, and it's the pick I'd default to for a front door. Anweller costs the most of all and answers a different question entirely, with IP67 sealing and a 24-month standby claim on a bike U-lock.

Wyze's exact advantage over eufy is the rescue port. eufy's exact advantage over Wyze is two more ways in and a second seller.

FAQ

Is a cordless fingerprint smart lock worth it over a keypad-only lock?

A cordless fingerprint smart lock is worth it if more than two people use the door daily, because a fingerprint takes under a second and needs nothing memorised. The eufy C220 and Wyze Bolt v2 both keep a keypad anyway, so you get codes as well as prints. For a door you use alone, the extra spend buys less.

Which is the better front door pick, eufy C220 or Wyze Bolt v2?

The better front door pick depends on your bigger fear. eufy C220 lists six unlock methods including app, keypad and physical key, and two sellers stock it. Wyze Bolt v2 lists four methods but adds a USB-C port that any power bank can revive, plus published BHMA2 and IP53 ratings. Fear lockouts, buy Wyze. Want breadth, buy eufy.

How much battery life should I expect from a cordless fingerprint smart lock?

Battery life you should expect divides by chemistry. Both AA deadbolts here claim around 8 months from 8 cells. Anweller's 320mAh rechargeable cell claims 24-month standby and about 4,000 unlocks per charge, while eLinkSmart cites low consumption without a figure. Evanshow publishes no battery spec at all, so plan on its keypad and 2 mechanical keys as your safety net.

Will a fingerprint deadbolt fit my existing door?

Whether a fingerprint deadbolt fits comes down to bore and thickness. Evanshow is the only pick publishing a range, 1.18 to 1.97 in on wooden doors, left or right swing. The eufy C220 and Wyze Bolt v2 replace a standard deadbolt but publish no thickness spec, so measure your door and confirm on the listing before ordering.

What is the most common mistake buying a cordless fingerprint smart lock?

The most common mistake is buying the wrong shape. Search results mix deadbolts, knobs, bike U-locks and cable locks together, so a 4.1 lb U-lock can look like a door lock in a grid of thumbnails. Second mistake: skipping the admin fingerprint. Evanshow warns that until an administrator print is registered, any finger opens the door.

Go measure your door thickness and look at the bore, then pick from the shape that matches. If it's a standard exterior deadbolt hole, the eufy C220 is the safe default, because six ways in means the odds of standing outside your own house are as low as this set gets. If you'd rather carry a power bank than a spare key, the Wyze Bolt v2 is the smarter version of the same lock. And if you came here for a bike, buy the bike lock. The 5ft cable and IP67 rating are doing a job no deadbolt can.
