Benefits & Use Cases
This smart lock is ideal for homeowners seeking enhanced security without compromising on convenience. Whether you’re tired of constantly hunting for keys, frequently hosting guests, or managing cleaning services, this lock streamlines access control. With the ability to generate temporary or permanent digital passcodes, you can grant trusted individuals—such as housekeepers, babysitters, or Airbnb guests—secure entry without needing physical keys. Real-time notifications ensure you’re always aware of who enters and when, adding peace of mind whether you’re at home or traveling.
Rental property owners will particularly appreciate the audit trail feature, which tracks every lock event—fingerprint scan, code entry, fob tap, or key use—providing transparency and accountability. In case of power outages or system glitches, the included mechanical keys offer reliable backup access. The lock’s compatibility with voice assistants like Alexa and Google Home allows seamless integration into existing smart ecosystems, enabling commands such as “Alexa, unlock the front door”—though full remote functionality requires pairing with a compatible Wi-Fi gateway.
With its rugged alloy design and long-lasting battery life, this lock performs reliably across various environments. Its intuitive touchscreen interface makes navigation simple, even for less tech-savvy users. And because installation takes under an hour using basic tools, homeowners can upgrade their security without downtime or added expense.
Important Notes
- A separate Wi-Fi gateway (not included) is required to enable internet-based features such as remote locking/unlocking from smartphones, real-time push notifications, and integration with voice assistants like Alexa and Google Assistant.
- Installation assumes compatibility with standard U.S.-style door prep; users should verify hinge orientation (left or right) before purchase. Professional installation is not recommended due to the DIY-friendly design.
- The device operates on disposable AA batteries only and does not support rechargeable power packs or USB-C charging.
- Package contents include: electronic lock unit, interior handle assembly, mounting hardware, two backup mechanical keys, user manual, and installation guide.
- While the lock is weather-resistant indoors, exposure to extreme moisture or temperature fluctuations may affect performance over time.

Helenâs excellent customer service
I bought this lock on Amazon last August. I was attracted by its beautiful appearance. It is very convenient to use and very practical. It can be unlocked in several ways, such as fingerprint, password, electronic key and ordinary key, which makes our life very convenient.Last month, I found that the lock was broken. I contacted the customer service by email. Helen responded to me quickly, replaced a new lock for me, and gave me a two-year warranty . I am very satisfied with the customer service’s ability to solve the problem quickly. I will recommend friends to buy their products.

Great technology and ease of use.
I was looking for a lock that would be easy to use for all of the people that I let into my house without handing out keys. It has been very useful because of the variety of ways you can unlock the door through fingerprint, passcode, e key or regular key. I like all of the security and the various ways you can generate a passcode. I also love that I can use the gateway and remotely lock and unlock the door in cases where I donât want to provide an access code to someone. I was having an issue getting my gateway connected to my lock and got in touch with customer service and Elaine couldnât have been more helpful. We ended up having a video call and she walked me through all of the steps and we were able to get everything working in perfect order. All in all, it has been a great purchase and would buy again.

Great customer service!
Weâve had this lock for a few months and love it.It has several options to unlock the door, and creates a sense of safety and ease getting in and out.Unfortunately, the motor in our lock went out a few months in. I reached out to customer service and April responded quickly. We had a replacement ordered within minutes of starting our conversation. I was sad to see our lock not work, but was so very pleased with the customer service of this product.

Nice Set
Installed easily and nice gold painted appearance (polished brass would be amazing) but requires attention to detail during install to ensure key lock tumbler in correct position or it will not release key when locked and interferes with deadbolt full range of motion. NOTE: Customer Service in US is third party information gathering only…Tech Support is in China and not available until after 8 p.m. EDT.I used Next Lock app and it worked flawlessly during very user friendly connecting process.

Amazing product and guest service
The door lock is very easy to use and it looks very luxurious. A guest service specialist helped me install it by walking me through the steps on FaceTime. They were very helpful and the door lock was well worth the money.
