If your car interior has scratches, here are a few possible solutions: toothpaste repair: For minor scratches, toothpaste can be used for repair. The chemicals contained in toothpaste help to remove scratches. All you need to do is squeeze the toothpaste on the scratch and wipe it gently with a clean wet towel. white vinegar removal: Use diluted white vinegar (about half water) to spray on the scratches, let it stand for a period of time, and wipe it clean with a dry towel. This method is suitable for light scratches, and can make the plastic surface brighter and cleaner. table wax repair: If toothpaste and white vinegar are not suitable, consider using a table wax. Spray evenly on the plastic parts around the scratches, wait a few minutes and then wipe with a clean wet towel, which can restore the luster of the plastic and cover the light-colored scratches. Professional repair: If the scratches are more serious, it is recommended to go to a professional auto repair shop for processing.

The reason why car keys are expensive is mainly due to their technical content and anti-theft performance. The technical content of car keys is reflected in the anti-theft performance, especially for high-end models, whose keys usually contain chips and complex systems, which require professional technology and equipment to match and configure. In addition, the keys of some imported models are prepared in the place of origin and need to be transported over long distances, which also increases the cost. For some high-end imported models, such as Audi and BMW, the process of formulating new keys needs to be carried out at the place of production, which not only increases costs, but may also lead to longer waiting times. For some economy cars, the cost of preparing new keys is relatively low, usually in 200 or 300 yuan.

The main difference between the auto parts sub-factory and the original factory lies in quality, price, source, shelf life, safety and so on. The following is the relevant introduction: Quality.

The price of auxiliary factory parts is lower, but the quality may not be guaranteed. Security.

For some non-critical accessories, such as air conditioning filters, navigation, etc., the auxiliary factory accessories can also meet the basic needs in terms of quality. Source. The original parts are usually produced by the parts suppliers designated by the main engine factory and bear the trademark logo of the main engine factory, while the auxiliary parts may be produced by various small manufacturers without unified inspection procedures and may not have the trademark logo of the main engine factory. Shelf life. Original parts usually have a longer shelf life with warranty instructions, while auxiliary parts may have a shorter shelf life and no clear warranty commitment. After-sales service. Original parts usually enjoy the after-sales service of automobile manufacturers, while the after-sales service of auxiliary parts may not be perfect.
