What are the reasons for the Baojun 730 key authentication failure?
4 Answers
Baojun 730 key authentication failure reasons are as follows: Battery depletion: When the car battery is dead, it can lead to key authentication failure, and charging is required to solve the problem. Water damage to the central control: If water enters during windshield film installation, it may flow into the central control system along the glass. A visit to the 4S shop for repair is necessary. Therefore, it is essential to inform the technician to be cautious during film installation, and placing a towel on the central control panel is recommended. Other factors: Electromagnetic interference nearby, presence of large power equipment in the vicinity, or being in a very open area, etc. Key anti-theft system: The car ignition key contains an electronic chip, each with a fixed ID (equivalent to an identification number). The car can only start when the key chip's ID matches the ID on the engine side.
I've encountered key authentication failures several times while driving the Baojun 730, mostly related to depleted key battery. The key remote requires small battery power, and prolonged use drains it until unrecognizable. You can open the key's back cover to check the battery model and replace it. Interference is another major issue—placing keys in wallets or near metallic phone accessories can block signals, making the car fail to recognize the key. The key itself might also be damaged, like unresponsive buttons or chip malfunction, requiring professional inspection. Occasionally, the car's receiver module malfunctions, especially prone to short circuits in humid weather, necessitating a repair shop check. When parking, avoid excessive distance or proximity to metal obstacles—these daily habits matter, as repeated failures compromise safety and require prompt fixing.
As a car enthusiast, I believe the main reason for the Baojun 730 key authentication failure is the blockage of key signal transmission. Insufficient battery power in the key is the most common issue, which can be resolved by replacing it with a new battery. External interference, such as being near strong electromagnetic fields or carrying electronic devices, can disrupt frequency matching. If the key hardware is damaged, such as stuck buttons or internal circuit problems, the system will not respond. Faults in the vehicle's receiver are also common, often caused by module aging or water damage. It's recommended to check the battery level first, then compare and test with a spare key. If neither works, consult a technician to diagnose whether the key and receiver module are in sync—some minor issues can be handled yourself. Occasionally, system software errors may require a restart or firmware update. Maintaining good habits can help avoid long-term issues.
Key authentication failure may be due to a weak battery. Try replacing it with a new one to see if that resolves the issue. Also check for signal interference – avoid placing the key near mobile phones or metal objects. The key itself could be damaged, or there might be an issue with the vehicle's receiver causing recognition problems. It's recommended to seek professional inspection to confirm the cause as soon as possible.
