Fantastic Lock - Use video Instructions – by Jane Ha on October 25, 2019

Very well-made lock, and works great so far. Using the video instruction will definitely shorten your installation time. It took me about 15-20 min after watching the video demo. Easy to program, set master code, and guess code.

Overall, Great product! Easy to install and easy to program. Highly recommended


Great upgrade and easy to understand instructions – on February 29, 2020

The installation was very simple and easy to follow. (If you have ever swapped a door handle there isn’t much of a difference). Setting up the code and additional codes was very easy as well. My mother in laws is a bit older and like the idea of it always being locked and can’t accidentally unlock it.


Great lock with features – by James Ting

Although it is not a wifi / app connected device, but it is really easy to install and it comes with clear instructions,

I put this to inner door inside the garage, and it well serves the purpose.

The screen is easy to clean, however, you need to tap it on to activate the screen then you may enter the code.

For now, I am happy with the purchase
