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.

Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

Handling claims with an overseas exporter works best when expectations are set before payment. Prevention: put the inspection standard, photo/video evidence requirements, and a dispute clause into the sales contract. Keep all chat records and payment receipts. Typical process if issues arise: 1) Notify the exporter within 48-72 hours of delivery with photos/videos as evidence. 2) Most disputes fall into two buckets: shipping damage (handled via marine insurance — this is why insurance matters) or undisclosed mechanical defects (handled per contract, often via partial refund, spare parts, or repair cost sharing). Realistic expectations: exporters rarely accept returns, so negotiate compensation instead. A reputable company will usually cover reasonable repair costs for defects confirmed to pre-exist shipment. Tip: for higher-value cars, hire a local third-party inspection at destination as final evidence — it strengthens any claim significantly.
