Great upgrade and easy to understand instructions – by Wh0M3 bought on February 29, 2020:
I got this for my Mother-in-law. I have a similar door lock and love it. She wanted one too so I got this one for her. 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.
Fantastic Lock – by Jane Ha on October 25, 2019:
Very well made lock, and works great so far. Use the video instruction will definitely shorten your installation time. It took me about 15-20 min after watching the video demo. Easy to program, to set master code and guess code.
Overall, Great product! Easy to install and easy to program. Highly recommended.

Perfect fit – by MAREK M. on December 7, 2019:
If this lock will work on my outside gate ( already installed ) at least 2 years I am going to give big 10 for this lock, is very solid made easy to installed and I did not have problem with programming as someone said ( just please read slowly but surely !!! )

Enhanced function

We have made many efforts on the security function of this touchscreen door handle.
You must be awkward to type the password when there is other people nearby. The anti-peep password function allows you to type in random digits, but can still access as long as the 1 correct password is embedded in the longer set of numbers.
And you might worry that others will copy your password by its tonal features. So we added a mute feature to this lock. Just press # to enable the function.

High-quality with lifetime support

No need to worry about the quality. The ST-668 Plus lock is solid and durable enough to be certified by FCC and CE certification. No afraid of rainy days. It has IP44 waterproof protection and is dustproof to withstand and function normally even in rainy days. So you can rest assured to use it outdoors.
If you have encounter any questions of installation or others, feel free to ask us by service@signstek.com, we are very willing to solve your problems and will reply in one day.
