2022 year BYD Qin PLUS EV all key lost using KD-X4

BYD offers two matching methods. The DMI model from 21 years ago can be directly matched, whether it's by add key or all key lost. For other model years, whether it's add key or all key lost, data collection is necessary. This video demonstrates the process of BYD collecting data to add a key in the event of all key lost. The steps are: 1. Generate the initial data collection original vehicle key ID; 2. Write the data back to the key, then collect five sets of data, and upload them for calculation. 3. After calculating the data, generate the emergency key and perform the key matching.
