PLUS LINKUpgrade your lock whenever and wherever you want

All Keyin products pursue
minimalism in nature.

This is to get rid of all unnecessary points and focus on real values that is directly linked to enhancing user experience.
But to some people, personalized values and functions are important to match their lifestyle.

• My grandmother always
  forgets our password,
  so we want to add a fingerprint option.
• Why is it not possible to add another
  option after installing the lock?
• My younger sister want to connect and control all the devices by using
  smartphone application

With 100 users, 100 situations can happen. With one single product, users may want all different functions.
And most of the needs will happen after installation.
That is why we built a platform that fixes the value of the product not when buying it, but during the whole lifecycle of the product.

With Keyin PLUS LINK, users can always upgrade the value and feature of their current products with ease. It is a platform, meaning new accessaries will come out with PLUS LINK, and they will be compatible with all PLUS LINK locks.
