A good lock for a lifetime 

A good lock, a business, a lifetime of pursuit

Since the establishment. YiF has been committed to making high quality locks as the original intention and mission of the company's development.

Little Lock, Big Difference

The lock looks small but not simple. Based on the pain points and usage habits of travel users, the R&D team is committed to research and development, so that the smallest 40 or 100 parts are arranged and rotated with precision in a limited space.

We firmly believe that a little more thorough preprocessing, a little more rigorous design details, and a little more stringent quality control standards will result in a better user experience.

We believe that doing everything to the best of our ability is the way to make a good lock.
