Fellow car owners should first check their car keys. The remote key fob contains a dedicated module specifically for engine starting. Simply pry open the casing, remove the old battery and replace it with a new one.

Last time I drove the Baojun 510, I also encountered an anti-theft authentication failure. It really gave me a hard time—the car wouldn't start, and I thought the key was broken. Later, I found out it was just a dead battery in the key. A simple two-dollar coin battery replacement fixed it. If the battery is fine, then the remote key might be malfunctioning. Sometimes, electromagnetic interference from being near a phone can cause this issue. Try restarting the vehicle or using a spare key. If it still doesn’t work, the anti-theft module might be faulty. In that case, it’s best not to tinker with it yourself—take it to a professional shop for a system reset or upgrade. Don’t delay, because if the anti-theft system fails, someone might unlock and open the car door. I recommend keeping a spare key in the car for emergencies. These lessons come from several repair experiences—safety first.
