What does the keyless entry function mean?

Keyless entry function is an unlocking feature of a car, which means the car key has remote sensing capability. When the key is brought close to the car door, the vehicle can detect the key within a certain distance and automatically unlock. When the key moves away from the car body, the doors automatically lock and enter an anti-theft alert state. This product utilizes RFID radio frequency technology and a vehicle identity code recognition system, pioneering the development of a miniaturized, low-power RF antenna solution. It integrates the remote control system with the keyless system while maintaining traditional vehicle circuit protection, achieving dual RF systems and dual anti-theft protection, providing convenience and security for car owners.

How to reset the engine fault light?

Engine fault light reset method: Simply pull out the fuse. Solutions for engine fault light illumination: Clean the engine: Once the engine fault light comes on, the owner should promptly clean the carbon deposits in the engine. Improve fuel quality: Domestic fuel currently cannot meet the requirements of high-performance engines, so owners can take steps to improve fuel quality themselves. Use higher-octane gasoline: After cleaning the engine, since most cars that comply with the National IV emission standards have an engine compression ratio of 10.0 or higher, these vehicles are not suitable for long-term use of gasoline below 95 octane. To maintain the engine in good working condition, owners can choose to use 95 or 97 octane gasoline, which usually resolves the engine fault light issue.

Can the 2020 Inspection Sticker Be Omitted?

2020 Inspection Sticker cannot be omitted. Starting from March 2020, many cities have piloted the digitalization of motor vehicle inspection qualification marks, eliminating paper stickers. Electronic certificates can be downloaded online, but this does not mean that inspection stickers can be omitted in all regions—only that electronic verification is available, which is important to note. The new policy combines the vehicle inspection and environmental protection test marks into one. Vehicles that pass the inspection no longer need to obtain a separate environmental protection mark. Motor vehicles only need to display the inspection qualification mark and compulsory insurance mark. Driving a motor vehicle without displaying the inspection qualification mark will result in a fine of 50 yuan and 1 penalty point. In severe cases, the traffic management department of the public security authority may impound the vehicle and require the owner to provide the corresponding license, mark, or complete the necessary procedures.

How to Transfer a License Plate Number to Someone Else?

License plate numbers cannot be transferred to someone else. The transfer or resale of license plate numbers is strictly prohibited. The original license plate number can only be applied for use on a new vehicle after the transfer or scrapping of the original vehicle. In essence, what is referred to as a "license plate transfer" is actually the binding of the license plate to the vehicle registration, making them inseparable. The transfer is achieved by changing the ownership of the vehicle and updating the vehicle information under the new owner's name. For license plate number transfers, a common method is allowing transfers between spouses. According to regulations, if one spouse transfers a locally registered vehicle under their name to the other spouse, who owns no vehicles and has no valid vehicle quota, the transfer can be processed directly with valid documents such as a marriage certificate, without the need to apply for a new quota. In other words, as long as the other party has no vehicle and has not applied for a quota, the vehicle can be transferred to their name at any time.
