Reasons for Baojun 510 Engine Anti-Theft Authentication Failure
2 Answers
Baojun 510 engine anti-theft authentication failure may result in phenomena such as brake failure, heavy steering wheel, and failure to start. The following are the related reasons for authentication failure: 1. Main reasons for authentication failure: First, it could be due to a mismatch between the remote key and the engine computer; Second, water ingress from the front windshield film (a very common reason), where water flows along the glass into the center console. 2. Mechanism of action: The engine anti-theft system cannot connect with the key. When the key fails, authentication failure will be displayed. The vehicle's engine electronic anti-theft system has an anti-theft converter embedded in the car key. When the key is inserted into the ignition switch lock cylinder and turned to the "ON" position, the electronic anti-theft ECU communicates with the key via radio frequency.
I've been driving the Baojun 510 for two years and encountered an anti-theft authentication failure, which was quite scary as I thought the car was stolen. The reason is usually that the key battery is dead—the small battery loses power after prolonged use, leading to failed authentication. Or there might be strong environmental interference, such as parking near a mall with lots of electronic devices disrupting the signal. That time, my car wouldn't start outside the supermarket, and restarting the vehicle didn’t help. Later, replacing the key battery fixed the issue. I recommend fellow drivers check their keys regularly—don’t wait until there’s a problem like I did. Carrying a spare key is also a good idea. When parking, choose locations with less interference to avoid the anti-theft system acting up. If failures happen frequently, it might be a faulty antenna module, requiring a repair shop’s inspection. In short, don’t panic—try simple solutions first, and ensuring driving safety is the top priority.
