Fumbling with keys is officially a thing of the past. After watching my neighbor install a smart door handle last fall, I decided it was time to upgrade my own home security system with something that didn’t involve metal keys that I constantly misplace. The SMONET Fingerprint Door Lock caught my eye not just for its sleek design, but also because it advertised itself as an eco-friendly option with lower power consumption than many competitors.
Three months and multiple house guests later, I can honestly say this smart entry solution has transformed how I think about home access. No more hiding keys under flower pots or worrying about who might have copies. But does it truly deliver on both security and environmental promises? Let’s get into the nitty-gritty of living with this tech-forward door upgrade.

This lock is perfect for homeowners who:
- Value convenience but won’t compromise on securityHave family members or regular visitors who need accessAre environmentally conscious and want energy-efficient home upgradesWant to eliminate physical keys from their daily routine
- Enjoy integrating smart technology throughout their home
However, I wouldn’t recommend this to:
- Renters without permission to change door hardwareHomeowners with extremely limited technical know-how (though the setup is fairly simple)People who experience frequent power outages and don’t want to rely on battery backups

Eco-Friendly Features That Actually Make a Difference
Let me start with what initially drew me to this particular model. The SMONET smart doorlock uses a power-efficient design that consumes significantly less energy than many competitors I researched. Here’s what makes it stand out:
Energy-Saving Sleep Mode
Unlike other smart locks that continuously pull power, this one includes an intelligent sleep mode that activates after periods of inactivity. This feature alone extends battery life by about 30% compared to my previous smart lock. I’ve been using the same set of batteries for three months now, and the app still shows 78% battery remaining.
Sustainable Materials
The packaging surprised me – minimal plastic, mostly recyclable cardboard, and even the instruction manual is printed on recycled paper. The handle itself contains some recycled aluminum components according to the manufacturer, though I’ll admit this isn’t something I can verify myself.
Low-Energy Connectivity
The Bluetooth Low Energy protocol this device uses pulls minimal power when connecting to your phone. I was skeptical this would affect real-world battery life, but after comparing notes with my neighbor’s non-eco model, there’s a noticeable difference.
I appreciate that SMONET didn’t just slap an “eco-friendly” label on the box without backing it up with actual energy-saving features. For homeowners looking to reduce their environmental footprint without compromising on security tech, this is a legitimate option.
Installation Experience: Easier Than Expected
I’ll be honest – I put off installing this smart door handle for a week because I assumed it would be a headache. I was wrong. The entire process took about 35 minutes, and that includes the time I spent looking for my screwdriver.
The package comes with detailed instructions and all necessary hardware. You’ll need basic tools (screwdriver, measuring tape), but nothing specialized. The lock fits standard door preparations, so if you’re replacing an existing deadbolt, you won’t need to drill new holes.
What impressed me was the thoughtful design of the installation process itself. The wiring connections are color-coded and can only fit together one way, preventing any potential electrical mistakes. The app setup afterward took another 10 minutes, mostly spent creating an account and connecting to my home WiFi.
One hiccup I did encounter: the template for marking screw holes wasn’t quite aligned correctly. I’d recommend double-checking measurements rather than relying solely on the provided template.
Daily Performance and Smart Features
Fingerprint Recognition
After using this lock daily for three months, I can confirm the fingerprint scanner is reliable about 95% of the time. It occasionally struggles if my fingers are wet or very cold, but the recognition speed is impressive – under half a second from touch to unlock.
I’ve registered all ten of my fingerprints plus my partner’s index fingers, and we haven’t experienced any unauthorized entries or false rejections. The system can store up to 100 unique fingerprints, which is overkill for most households but nice to have.
App Control and Remote Access
The companion app is surprisingly well-designed. I’ve used plenty of smart home apps that feel like afterthoughts, but this one is intuitive and hasn’t crashed once. I particularly value the ability to:
- Check lock/unlock status remotelyCreate and send temporary access codes to visitorsView entry logs (who entered and when)
- Receive notifications when the door is unlocked
When my in-laws visited while we were at work, I created a temporary code that expired after their three-day stay. No key exchange needed, and I received a notification when they arrived. This feature alone justified the purchase for me.
Smart Home Integration
The smart door handle connects to both Alexa and Google Assistant, though I primarily use Google in my home. Voice commands work reliably for checking lock status (“Hey Google, is the front door locked?”), but for security reasons, unlocking requires a PIN spoken aloud – a reasonable safety precaution.
It also integrates with Samsung SmartThings, allowing me to include the lock in home automation routines. I’ve set it to automatically lock at 11 PM each night, which has saved me countless trips downstairs to check the door.
Design and Build Quality
The SMONET smart lock has a clean, modern aesthetic that has actually improved the appearance of my front door. Available in three finishes (I chose matte black), it strikes a good balance between contemporary design and classic door hardware styling.
The build quality feels substantial – not flimsy like some smart home products. The metal components have a satisfying weight, and the keypad buttons provide clear tactile feedback when pressed. After three months of multiple daily uses, none of the buttons show signs of wearing out.
The fingerprint reader is subtly integrated into the handle design rather than appearing as an obvious technological add-on. This integration gives the whole unit a more sophisticated look than some competing models that look overly “techy.”
Honest Pros and Cons
What I Love:
- Genuine energy efficiency that extends battery life significantlyFast, reliable fingerprint recognitionWell-designed app with useful remote featuresMultiple entry methods (fingerprint, code, app, physical key backup)Easy installation process for average homeownersAttractive design that enhances door appearance
- Temporary access codes for visitors
What Could Be Better:
- Price is higher than basic smart locks (though justified by features)Fingerprint reader struggles with wet fingersInstallation template wasn’t perfectly alignedAuto-lock feature sometimes activates while the door is still open
- App occasionally sends delayed notifications (5-10 seconds after events)
How It Compares: SMONET vs. August Smart Lock Pro
Before choosing the SMONET, I seriously considered the August Smart Lock Pro. Both are quality products, but they differ in several key ways:
Installation
The August attaches to your existing deadbolt, making installation potentially easier but limiting its visual transformation of your door. The SMONET replaces your entire lock mechanism, requiring a bit more work but providing a complete aesthetic upgrade.
Features
The August lacks built-in keypad and fingerprint reader (though you can buy a separate keypad). The SMONET integrates all access methods into one unit, which I find more elegant and convenient.
Energy Efficiency
This is where the SMONET clearly wins. The August Smart Lock Pro typically needs battery replacement every 3-4 months according to most reviews, while the SMONET’s eco-mode extends this to 8-12 months in my experience.
Price
The August typically costs about $30 more than the SMONET, yet offers fewer integrated features. For environmentally conscious homeowners, the SMONET provides better value while consuming less power.
For homeowners primarily focused on retrofitting existing hardware without replacing visible components, the August might make more sense. But for anyone wanting an all-in-one solution with better energy efficiency, the SMONET is the superior choice.
Real Buyer Questions
Does this smart door handle work with thick doors?
Yes, the SMONET works with standard residential doors between 1-3/8″ to 2″ thick. For thicker custom doors, you might need an extension kit (sold separately). I installed mine on a 1-3/4″ door with no issues.
What happens if the batteries die while I’m out?
Two safety measures prevent lockouts: First, the app starts sending low-battery warnings weeks before depletion. Second, there’s an emergency physical key override and a hidden USB-C emergency power port on the bottom. You can connect any power bank to give it enough juice to unlock and replace batteries.
Can I still use this during power outages?
Absolutely. Since the lock runs on batteries, it continues working during power outages. The only limitation is that remote access through WiFi won’t work if your internet router is down. Local Bluetooth control via your phone still functions, as does fingerprint and keypad access.
How secure is this compared to traditional locks?
The SMONET uses 128-bit encryption for digital communications and features an ANSI Grade 2 physical lock mechanism (the standard for residential security). It’s actually more secure than many traditional locks because it prevents lock-picking and bumping techniques. Plus, you’ll know exactly who entered and when, unlike with traditional keys that can be copied without your knowledge.
Can I install this on a rental property?
Technically yes, but I’d strongly recommend getting landlord permission first. Installation requires replacing the existing lock hardware, though you can keep the original to reinstall when moving out. The good news is the installation doesn’t damage the door and uses standard door preparations.
Final Verdict: A Worthy Investment for Eco-Conscious Homeowners
After three months of daily use, the SMONET smart door handle has earned its place on my front door. The combination of convenience, security, and genuine energy efficiency makes it an excellent choice for homeowners looking to modernize their entryway without unnecessarily contributing to electronic waste or excessive battery consumption.
What surprised me most was how quickly this lock became an essential part of my smart home ecosystem rather than just a novelty. Creating temporary access codes for dog walkers, monitoring entries while on vacation, and never again worrying about lost keys has genuinely reduced small daily stresses. And knowing it consumes significantly less power than alternatives gives me that extra bit of satisfaction.
Is it perfect? No – the occasional damp-finger reading failure and the higher upfront cost compared to traditional locks are legitimate considerations. But for environmentally mindful homeowners who value both security and convenience, this smart doorlock strikes an impressive balance that few competitors match.
