If I want to upgrade the factory halogen headlights to LED headlights myself, and it causes the vehicle's BCM (Body Control Module) to lock, can you assist in unlocking it?
It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blind electrical modifications on modern integrated circuit vehicles.
