AI Verdict
This is a zinc-material handle lock with 5 keyless entry methods, Bluetooth app control, and optional Wi-Fi for remote access, designed for DIY installation on standard doors.
This lock is a situational fit because its core functionality (fingerprint, keypad, app control via Bluetooth) is strong for its price band, especially for DIY installation. However, its advertised remote access and smart home compatibility are contingent on purchasing an optional Wi-Fi gateway, which isn't clearly stated upfront in all marketing. Without the gateway, it's a local smart lock.
If remote Wi-Fi access is a must-have, look for models with integrated Wi-Fi or clearly bundle the necessary gateway.

What Buyers Say
The biggest takeaway is how many users praise the fast and accurate fingerprint reader, often unlocking in under 0.3 seconds, which is a huge convenience for daily use. Many also found the DIY installation surprisingly simple, often taking less than 30 minutes, even for those not experienced with smart locks. However, a recurring point of confusion is the Wi-Fi functionality; remote access and voice control are not built-in and require an extra, optional gateway. The app itself is generally well-received for its user-friendliness and ability to manage access locally.
“Okay, so I got this thing because I'm always losing my keys, and the fingerprint thing is actually super fast, like, no joke, it just works, but seriously, why isn't the Wi-Fi built in, I had to buy another box for that!”

Frequently Asked Questions
Does this lock have built-in Wi-Fi for remote access?
No, the lock primarily uses Bluetooth for app control when you are in range. For Wi-Fi remote access, Alexa, or Google Assistant compatibility, you need to purchase the optional Sifely WiFi Gateway separately.
What type of batteries does this lock use and are they included?
The lock requires four AA batteries. These batteries are not included with the lock, so you will need to purchase them before installation.
How many ways can I unlock this door?
You can unlock the door in five different ways: using your fingerprint, a keypad code, the mobile app via Bluetooth, a key fob, or a traditional physical key.
Is the installation process difficult for a DIYer?
Many users report that installation is straightforward and can be completed in 10-30 minutes with just a Phillips screwdriver, without requiring extra drilling for most standard doors. The handle is also reversible for left or right-handed doors.
Can I disable the auto-lock feature?
Yes, the auto-lock feature is customizable and can be disabled if you prefer the door not to lock automatically after a set time.
Buying Guide
When you're looking at smart locks, you need to decide how 'smart' you actually need it to be right out of the box. Many locks, like this one, offer a ton of keyless entry options locally, which is fantastic for convenience. But if you want to unlock your door from your phone when you're not home, or tell Alexa to do it, that's where you often hit a hidden cost: an extra Wi-Fi bridge. Always check if 'remote access' means built-in Wi-Fi or if it's an add-on. Also, consider battery life; constant Wi-Fi drains batteries much faster than Bluetooth.
Connectivity (Bluetooth vs. Wi-Fi)
Bluetooth lets you control the lock with your phone when you're nearby, like standing at your door. Wi-Fi (often via a separate gateway) lets you control it from anywhere in the world, like checking if you locked up after leaving for vacation. Think of Bluetooth as a short-range walkie-talkie and Wi-Fi as a global phone call.
Entry Methods (Fingerprint, Keypad, Fob, Key)
More entry methods mean more flexibility for different users. Fingerprint is fast for you, a keypad code is easy for guests, a fob is simple for kids, and a physical key is your backup if batteries die. It's like having multiple ways to get into your house, ensuring you're never locked out.
Auto-Lock
This feature automatically locks your door after a set time, so you don't have to remember to do it. It's like having a helpful robot that always double-checks your door, giving you peace of mind that your home is secure even if you're in a rush.
Alternatives
If you need integrated Wi-Fi for remote access without an extra purchase, look for models explicitly stating 'built-in Wi-Fi' or 'no hub required'. If you prioritize maximum battery life and only need local control, a Bluetooth-only model might be sufficient.
