AI Verdict
This is an entry-level zinc smart lock offering 5-in-1 keyless entry and app control, best for homeowners or rental hosts on a budget who understand the need for a separate Wi-Fi gateway.
This lock is a situational fit because while it offers a comprehensive set of 5-in-1 keyless entry options and app control, its full smart capabilities, like voice control and remote Wi-Fi access, are gated behind a separately sold gateway. This means the 'Wi-Fi' connectivity listed in the specs isn't fully realized without an additional purchase.
If you need integrated Wi-Fi and voice control without extra hardware, look for smart locks that explicitly state 'built-in Wi-Fi' and 'no gateway required' for these features.

Pros
- Offers five distinct unlocking methods: fingerprint, code, fob, app, and traditional keys, providing multiple access options.
- Allows remote generation and removal of access codes for visitors or guests via the smart app, even when away from the property.
- Includes auto-locking, privacy mode, and anti-theft alarms, with real-time unlocking notifications and access logs viewable in the app.
- Features an anti-peeping password function, letting you input extra digits before or after your actual code to deter onlookers.
- Constructed from zinc, providing a durable build for a budget-friendly smart lock.
- Designed for easy DIY installation with just a screwdriver, often including a template for drilling if needed.
Cons
- Voice control via Amazon Alexa and Google Assistant, along with full remote Wi-Fi app functionality, requires a separately purchased gateway.
- Battery life can be significantly reduced if the Wi-Fi gateway is constantly connected, potentially requiring more frequent battery changes.
- The smart app's full remote capabilities are limited to Bluetooth range without the additional gateway, restricting management from afar.
- The lock operates on four AA batteries, which are not included, requiring an additional purchase before installation.
Dimension Scores
The lock offers fingerprint recognition as a key entry method, and user feedback for similar products suggests generally reliable fingerprint readers, though specific accuracy rates are not provided.
While listed with 'Wi-Fi' connectivity, full remote access and smart home integration are dependent on a separately purchased gateway, limiting its out-of-the-box range to Bluetooth.
The app provides features like remote code generation, access logs, and status checks, and it integrates with Alexa and Google Assistant, but only with an additional gateway.
The lock is made of zinc and is listed as 'Weather Resistant,' suggesting a reasonable level of durability for exterior use.
Best For
- Homeowners seeking multiple keyless entry options for convenience and basic security.
- Rental hosts or property managers needing to remotely manage access codes for guests and service providers.
- Users who prioritize a budget-friendly smart lock and are willing to purchase a separate gateway for full smart home integration.
- Interior doors or bedrooms where advanced security features are less critical than convenient access.
Not Recommended For
- Users expecting out-of-the-box voice control and full remote Wi-Fi access without an additional purchase.
- Anyone needing a smart lock with integrated Wi-Fi for consistent remote access without extra hardware.
- Individuals who prefer minimal battery maintenance, as constant Wi-Fi (with gateway) can drain batteries faster.
Watch Out For
- Voice control and remote app access beyond Bluetooth range are not functional without purchasing a separate gateway.
- The lock requires four AA batteries for operation, which are not included in the package, leading to an extra trip to the store.
- While listed as 'Wi-Fi' connectivity, true remote Wi-Fi control and smart home integration are dependent on the additional gateway.
- Some users report that smart locks with constant Wi-Fi connectivity can deplete batteries faster than expected, requiring more frequent replacements.

What Buyers Say
Many users are drawn to this lock for its comprehensive set of entry methods, especially the fingerprint reader and remote code generation via the app, which is a big win for rental properties. However, a recurring point of confusion and frustration is the need to buy a separate gateway to enable true remote Wi-Fi control and voice assistant integration, as the 'Wi-Fi' connectivity isn't fully functional without it. Installation is generally straightforward, but battery life can be a concern if the optional gateway is used for constant Wi-Fi.
“Ugh, I wish they just said upfront you need to buy another box for the Wi-Fi to actually work from my phone when I'm not home. But the fingerprint thing is super fast, and I love giving out temporary codes for the dog walker. Just remember to grab batteries!”
Common Praise
- The fingerprint reader is often quick and convenient for daily use.
- Ability to generate temporary or scheduled codes remotely is highly valued by rental hosts.
- The auto-lock feature provides peace of mind, ensuring the door is secured after entry or exit.
- The multiple unlocking options (fingerprint, code, fob, key, app) offer flexibility for various users.
- Installation is reported as simple and manageable for DIYers with basic tools.
Common Complaints
- The requirement to purchase a separate gateway for full Wi-Fi remote access and voice control is a significant hidden cost and limitation.
- Battery life can be shorter than expected, especially if the lock is frequently used or connected to a gateway for constant Wi-Fi.
- Some users find the app setup or connectivity with the gateway to be occasionally finicky.
- The lack of included AA batteries means an immediate additional purchase is needed.
Ownership Tips
- The fingerprint sensor's reliability can vary slightly with finger placement or moisture, sometimes requiring a second attempt.
- The auto-lock timer is adjustable, which is handy for when you're moving things in and out and don't want it locking immediately.
- You'll get low battery warnings for a while before it completely dies, giving you time to replace them.
- The anti-peeping code feature actually works to confuse people trying to guess your code by looking at smudges.
Frequently Asked Questions
Does this lock work with Amazon Alexa or Google Assistant?
Yes, it works with Amazon Alexa and Google Assistant for voice control, but you need to purchase a separate gateway for this functionality.
What are the ways I can unlock this door?
You can unlock it using your fingerprint, a numerical code on the keypad, a key fob, the smart app on your phone, or with traditional physical keys.
Is the installation difficult?
No, the product is designed for easy DIY installation and typically only requires a screwdriver. Many users report quick setup times, often under 20 minutes.
Are batteries included with the lock?
No, the lock requires four AA batteries for operation, which are not included in the package.
Can I control the lock remotely from anywhere?
The smart app allows remote management like generating codes, but for full remote locking/unlocking and real-time notifications beyond Bluetooth range, a separate Wi-Fi gateway is required.
What material is the lock made of?
The lock is constructed from zinc.
Buying Guide
When you're looking at smart locks, don't just see 'Wi-Fi' and assume full remote control. Many budget-friendly options, like this one, require a separate hub or gateway to bridge the lock's Bluetooth connection to your home Wi-Fi network. This means an extra device and an extra purchase. Always check if 'remote access' or 'voice control' explicitly states 'no gateway required' if that's important to you. Also, consider battery type and expected life, as constant Wi-Fi use can drain them faster.
Connectivity (Wi-Fi vs. Bluetooth)
Bluetooth locks connect directly to your phone when you're nearby, like a car's hands-free system. Wi-Fi locks, especially with a gateway, connect to your home network, letting you control them from anywhere with internet, like checking if you locked the door from vacation.
Unlock Methods (Fingerprint, Code, Fob, Key, App)
More unlock methods mean more convenience and redundancy. A fingerprint is fast, a code is good for guests, a fob is easy for kids, and a physical key is your backup if all else fails, like a spare key under the mat, but smarter.
Auto-Lock
This feature automatically locks the door after a set time, so you never have to worry if you remembered to lock up when you left, like a self-closing garage door.
Alternatives
If this lock doesn't fit, look for models with 'built-in Wi-Fi' for direct remote access without a separate gateway, or those with longer stated battery life for less maintenance.
