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 blindly modifying the electrical systems of modern integrated circuit vehicles.

A proper inspection covers roughly 200 checkpoints in four areas: 1. Body and paint: panel gaps, paint thickness readings, signs of accident repair. 2. Mechanical: engine health report, transmission behavior, suspension, underbody on a lift, fluid condition. 3. Electronics: full OBD diagnostic scan, airbag history, all lights and comfort features. 4. Documentation: VIN matches everywhere, no lien or seizure record. You can book directly with inspection companies in Guangzhou, Shanghai, or Tianjin (typically USD 100–250) without going through the seller—give them the yard address and car details, and they send a report with photos and video within 1–2 days. Pay the inspection fee yourself so the inspector answers to you, not the exporter.

It's extremely difficult. The security level of Chinese brand immobilizers is very high, and you must connect a specialized factory computer to the vehicle's OBD and be online with the domestic server to match it. Losing all keys usually means you need to replace the entire lock cylinder and anti-theft control module while overseas.
