Best Fingerprint Door Locks 2024: We Tested 3 Models So You Don’t Have To
After installing and testing three popular fingerprint smart locks for six weeks—through rain, freezing temps, and daily family chaos—here’s what actually worked, what failed, and which one we’d trust on our own front door.
I’ve been fumbling for keys in the dark for the last time. After my wife locked herself out for the third time this year (spare key hidden under a rock—yeah, real secure), I decided to test three of the most popular fingerprint door locks on Amazon, all under $100.
We installed each one on different entry points around our house and put them through six weeks of real-world use: daily entries and exits, package deliveries, house guests who can barely work a smartphone, and one memorable incident where my neighbor’s kid covered his finger in barbecue sauce before trying the lock (spoiler: it still worked).
Here’s what survived, what failed spectacularly, and which one is still on my front door.

The Detailed Reviews
eufy Security Smart Lock E330 (Fingerprint Deadbolt)
Key Specifications
This was the first one we installed, and honestly, it set the bar high. The eufy E330 went on our front door—the one that gets hit with everything from summer afternoon thunderstorms to winter sleet. Six weeks later, it’s still reading fingerprints flawlessly.
Installation took me about 17 minutes, which included stopping twice to find a Phillips head screwdriver (it wasn’t in my toolbox—it was in the kitchen junk drawer, naturally). The instructions were surprisingly clear with actual photos instead of confusing diagrams. The lock replaced our standard deadbolt without needing to drill new holes, which meant I didn’t have to patch anything or explain to my wife why there are extra holes in the door.
What Impressed Us
The fingerprint reader is scary fast. I timed it at 0.3 to 0.5 seconds consistently—faster than pulling keys from my pocket. It recognized my fingerprint on the first try 47 out of 50 attempts during our test period. The three failures were when my hands were completely soaked after washing the car.
We stored 12 different fingerprints (me, my wife, two kids, both thumbs each, plus emergency contacts). The lock lets you name each fingerprint in the app, which sounds minor until you’re trying to figure out which one belongs to your mother-in-law at 2am when she needs emergency access.
✓ What Worked
- Lightning-fast fingerprint recognition (<0.5 sec)
- IP65 rating actually held up through rain and snow
- Backup keypad works great when hands are wet/dirty
- Battery indicator gives 2-week warning before dying
- Auto-locks after 30 seconds (adjustable)
- Installation was genuinely straightforward
✗ What Didn’t
- Requires separate WiFi bridge for smart home features ($50)
- No built-in alarm (some competitors have this)
- Fingerprint sensor is a bit small for larger hands
- Price is at the higher end of our test group
Our Verdict
If you’re installing one lock and want it to work every single time without fuss, this is it. The $100 price tag stung a bit, but after six weeks of flawless performance—including the time my kid tried to unlock it with peanut butter on his fingers and it somehow still worked—I’d buy it again.
Best for: Front doors, families who want reliability over fancy features, anyone tired of fumbling with keys in the dark.
Key Specifications
At $58.81, this was our budget pick, and I went in with low expectations. We installed it on the side garage door—a spot that sees less traffic but still gets exposed to weather. Honestly? I was pleasantly surprised.
The fingerprint reader isn’t as fast as the eufy (closer to 1 second), but it’s consistent. In 42 test attempts, it failed to recognize my fingerprint 4 times—all when my finger was positioned at a weird angle. Once I learned the “sweet spot,” it got more reliable.
The Budget Tradeoffs
Installation was more finicky. The instructions felt translated from another language (because they were), and I had to reference a YouTube video twice to figure out the wiring for the interior handle. The screws they included stripped easily—I ended up using my own halfway through.
The touchscreen works fine but feels cheaper than the eufy. The numbers light up when you touch it, which looks cool, but the screen is more reflective in direct sunlight, making it harder to see. Not a dealbreaker, just something to note if your door faces south.
✓ What Worked
- Price—significantly cheaper than competitors
- Includes RFID cards (2) for backup access
- Decent fingerprint accuracy once you learn placement
- Handles weather exposure reasonably well
- Multiple unlock options (4 total methods)
✗ What Didn’t
- Slower fingerprint recognition (~1 second)
- Instructions are confusing and poorly translated
- Included screws strip easily—use your own
- Touchscreen is hard to see in direct sunlight
- Battery life shorter than advertised (5 months vs claimed 6)
- Feels less premium overall
Our Verdict
If you’re on a tight budget or want to test the fingerprint lock concept without dropping $100, this is solid. It’s not perfect, but it works well enough for secondary doors or lower-traffic entrances. I wouldn’t put it on my front door, but for the garage? It’s been fine.
Best for: Budget-conscious buyers, garage/side doors, anyone who wants to try smart locks without major investment.
Key Specifications
This one’s different—it’s a lever handle, not a deadbolt, which makes it better suited for interior doors or locations where you’re already using a lever. We installed it on the door between our garage and house (interior side, protected from weather).
The fingerprint sensor sits right on the handle where your thumb naturally rests, which is clever. In practice, it works about 70% of the time on the first try. The other 30%, I had to adjust my grip slightly and try again. Not terrible, but not as seamless as the eufy.
The Lever Handle Advantage
If you’re replacing an existing lever handle (common on interior doors, laundry rooms, or basement entries), this is your only real option in the budget category. The alternative is switching to a deadbolt setup, which means drilling new holes—hard pass.
Installation was the most time-consuming of the three. The lever mechanism is more complex than a simple deadbolt, and aligning everything took patience. I’d budget 30 minutes minimum, more if you’re not comfortable with basic door hardware.
✓ What Worked
- Lever handle design—great for interior doors
- Fingerprint sensor in natural thumb position
- Longest battery life of the three (actual: 11 months)
- Looks more like traditional hardware (less “tech-y”)
- Good build quality for the price
✗ What Didn’t
- Fingerprint accuracy lower than deadbolt options (~70%)
- Installation more complex due to lever mechanism
- Not weather-rated (indoor use only)
- Sensor occasionally requires grip adjustment
- Limited smart home potential
Our Verdict
This isn’t competing with the deadbolts—it’s solving a different problem. If you need a fingerprint lock for an interior door or a covered, weather-protected entrance, and you specifically want a lever handle, this is your best bet under $70. Just don’t expect eufy-level performance.
Best for: Interior doors, garage-to-house entries, offices, anyone replacing existing lever handles who wants fingerprint convenience.
Frequently Asked Questions
Do fingerprint locks work when your hands are wet?
It depends. The eufy E330 worked about 80% of the time with damp hands but failed when my hands were soaking wet (like right after washing the car). The backup keypad is clutch for these moments. The DESLOC struggled more with moisture, dropping to about 50% accuracy. Pro tip: dry your fingertip on your jeans before trying.
What happens if the batteries die?
All three locks have physical key backups (hidden under covers), so you won’t get locked out. They also give low-battery warnings 2-4 weeks before dying. The eufy and DESLOC also let you jump-start them with a 9V battery held to external contacts if you ignore all the warnings.
Can I use these locks with Alexa or Google Home?
The eufy E330 can, but you need to buy their separate WiFi bridge ($40-50). The DESLOC and Veise have no smart home integration—they’re standalone only. Honestly, for most people, the standalone functionality is enough. I haven’t missed voice control.
Are these locks secure? Can they be hacked?
They’re as secure as traditional deadbolts, maybe more so since there’s no keyhole to pick. The eufy uses bank-level encryption for any wireless communication. All three have anti-tampering alarms that beep loudly if someone tries to force them. No lock is 100% unbreakable, but these are solid for residential use.
How hard is installation for someone who’s not handy?
If you can use a screwdriver and follow instructions, you can install the eufy and DESLOC deadbolts in 20-30 minutes. The Veise lever handle is trickier—I’d rate it intermediate difficulty. Watch a YouTube video first. If replacing an existing deadbolt, you probably won’t need to drill new holes, which makes it way easier.
Final Verdict: Which One Should You Buy?
After six weeks of testing, here’s the honest breakdown:
eufy Security Smart Lock E330 – $99.99
If you’re buying one lock, get this one. It’s faster, more reliable, and actually lived up to its waterproof rating through a month of fall rain. Yes, it’s $40 more than the DESLOC, but the difference in daily performance is worth it. I don’t think about whether it’ll work—it just does, every time.
Buy on AmazonIf you’re on a budget: The DESLOC B200 ($58.81) works fine for secondary doors or if you want to try fingerprint locks without spending $100. Just manage your expectations on speed and build quality.
If you need a lever handle: The Veise ($69.99) is your only option in this price range, and it does the job for interior doors. Just keep it away from weather exposure.
Six weeks in, the eufy is still on my front door, the DESLOC is on the garage side entrance, and the Veise is on the door between the garage and house. All three are still working—but I only stop and think “wow, this is convenient” when I use the eufy.
