The automotive parts manufacturing enterprise has several core businesses including the production of automotive smart keys, contactor power bases, contact seats, and wiring harnesses. It has formed a dedicated R&D team for product development and technological innovation, enabling continuous breakthroughs in process optimization, automated production, cost control, and quality improvement. Chairman Chen Xinzhi stated that most of the smart car keys they sell are independently developed, and they have also combined high-end materials with advanced technologies to produce ceramic keys, which are at the forefront of the industry.

To foster long-term development, the company has invested over 6 million yuan in the past three years to update almost all of the outdated equipment in its workshop. It also plans to invest over 8 million yuan to build a new automated spraying workshop. In 2025, Guizhou Huayongxin took its independently developed car keys to the 2025 CIAAF Indonesia International Auto Accessories Exhibition and the Automotive Parts Expo in Warsaw, Poland. To date, the company has achieved sales exceeding 200 million yuan and paid over 15 million yuan in various taxes and fees.
