Quanding, a subsidiary of Dalian Union, launched a solution for car keyless entry based on Qualcomm csrb31024.

After decades of evolution, the vehicle entry system has gradually changed from mechanical and remote control to passive pase system (keyless entry and start system), and pase system is simple and easy to use, convenient and fast, which has been gradually recognized by consumers. However, with the maturity of mobile communication technology and cloud services, many parts manufacturers began to layout the latest generation of smart access system.

The general assembly has launched a keyless entry system based on Qualcomm csrb31024 using ble technology. As an upgrade of the previous generation product csr1010, it can support the bt5.0 standard and facilitate the certification of new products.
