【3-in-1 Smart Access】Our Smart Door Knob provides fingerprint recognition (0.5s fast unlock), encrypted app control via WiFi/Bluetooth, and a hidden mechanical keyhole – triple security layers adapt to your lifestyle while maintaining 24/7 home protection. 【Stylish and Durable Construction】This smart door handle features a 500-pound impact-resistant stainless steel and aluminum alloy frame to resist violent attacks. The tamper-proof design combines a classic round door handle shape with a modern LED indicator and successful unlock confirmation. 【Biometric Security System】The door lock has biometric capabilities and supports App control, which allows for easy fingerprint management.

Remotely create/delete fingerprints, set temporary access codes for guests, and receive intrusion alerts through the companion app. (Wi-Fi settings require purchasing a gateway for networking). Suitable for Airbnb hosts and property managers, create time codes that expire automatically (12 hours/3 days/1 week options). Monitor real-time access through the app’s encrypted activity log – perfect for verifying cleaner schedules or tenant compliance. 【Convenient Charging & Easy Installation】Designed for 1.18″-2.17″ thick US standard doors (wood/steel/fireproof). No wiring required – just replace the existing door handle with the included template and tools. Refer to the instructions for installation and follow the “UP” sign. The fingerprint door lock has a built-in 400mAh rechargeable battery, which takes 3 to 4 hours to fully charge (USBA-TypeC cable required). Automatic low battery warning activates at 15% capacity.

Awesome security knob. It’s great to keep inside doors secured.
If you love safety gadgets, this is definitely one to purchase. This door knob was charged via USB C before use. Don’t fret, it comes with keys to unlock in case the knob goes dead. The install was super easy. Had the old hardware uninstalled and the new one installed within 15 minutes. I’m a visual person and really didn’t require instructions only to make sure the lock squares lined up on both sides. I love that I was able to set up 2 users fingerprint access. Also, the app reviews speak for itself. I’m in love and will definitely purchase more locks for my home.

Love it
This lock was easy to install and I love the design of it. It has different functionality, is durable and fits standard doors. It is definitely worth the money.

The Jetsons family home door knob
This door knob makes me feel like I’m living in the future with George Jetson. It allows me to use my finger print or a code to lock and unlock my bedroom door. Great addition for a front door, back door, garage door or bedroom. Any door that uses a typical door handle can make you feel futuristic as well. Technology has come a long way! Door includes hardware, keys and instruction manual for set up and use. Really is a great addition to any new home, and an awesome way to show off to friends and family.

Lock it up
When moving into my new unit I was met with something similar for my front door and my landlord explain to me the features of it and how it worked I’ve seen something like the key fob you would have you and other locations but not necessarily the fingerprint door lock when I came across this I thought hey I’ve been going to secure some access so I’m certain areas of my home so why not give it a try the shipping of course came very quickly no problems with that at all upon opening the box there is a manual that is very self-explanatory by the instructions that are fold and clear there’s also pictures there to Aiden assist with complete setup the downloading of the app it was very quick and easy Bluetooth capability to sync my device with the smart system also very easy to set up I love the fact that it has four different lock and unlock functionalities from the app itself, or the code you set up yourself , the fingerprint, and it doesn’t have to just be the thumbprint it can be any finger as long as you properly set it up. lastly you have a manual key if all else fails however I’m really happy with this purchase and definitely recommend it if you’re looking for some modern security.

Loving This Door Knob
The Hei Liang doorknob is a well-constructed, solid biometric doorknob. Installation was very simple, and the design is straightforward for what I need. The app does a good job of allowing you to manage functionality of the knobs operation.The one star missing is also tied to the app as I have had a few situations where I lost connectivity and had to log back in to perform commands and/or check statuses. This – however – does not take away from the main function of the device (which you can still control from the doorknob itself).Overall, a great buy.

Smooth operation
Love this new lock. It works great. Nice for recording when door is opened and a special feature to have text messages of you pay the fee. Love not having to use a key and only needing a finger print. Feels solid and very easy to open.

I recently installed this Smart Door Knob with Keypad in my Airbnb, and it’s been a fantastic upgrade. The fingerprint sensor and app control make check-ins super convenient for guests, and the keypad ensures easy access without needing physical keys. Installation was straightforward, and the sleek design adds a modern touch to the door. Highly recommend it for any rental property or home!

Amazing lock, you can leave it in a mode where its like a regular knob without a lock or set it for fingerprint or only app unlock and it works with your Alexa or Google Home!!! Great product but definitely worth the steep cost.
