It should be noted that if the car's engine anti-theft light flashes once every 1 to 2 seconds, it is normal. This indicates that the car's engine has entered the anti-theft state. This is a normal phenomenon, and the owner does not need to deactivate it. Moreover, the power consumption is minimal, and it poses no problem for the battery. The vehicle anti-theft system will lock the vehicle, making it impossible to deactivate the anti-theft mode, open the doors, or start the engine using the remote control. It is necessary to open the car with a mechanical key and either recharge or replace the battery.
Encountered the situation where the theft deterrent light on the Besturn B50 keeps flashing, I had a similar issue a while ago, and it really worried me at the time. This usually indicates a problem with the anti-theft system, possibly due to the key not being recognized properly or a fault in the system itself. First, try some simple methods: use the spare key to start the vehicle and see if the light continues to flash; if that doesn’t work, turn the car off and restart it a few times, as sometimes the system needs a reset. Additionally, check if the key battery is dead—replacing it with a new one might solve the problem. If none of these methods work, it’s likely there’s a wiring issue or a faulty control module, which requires professional repair—don’t try to fix it yourself to avoid causing more damage. The anti-theft system protects your car’s security and shouldn’t be ignored; getting it fixed early can save you trouble later on.
The anti-theft light keeps flashing, let me share some insights from experience. Usually, the main culprit is poor recognition of the key chip. First, check if the key battery is worn out—try replacing it. If it's the original key, signal interference might be the issue; move away any phones or electronic devices nearby and try restarting. Alternatively, there could be a system software glitch—turn off the car and restart a few times to see if it self-corrects. If all else fails, don’t force it—a locked anti-theft system could render the vehicle inoperable, which is risky. It’s best to visit a 4S shop or repair center for a professional check on fuses and circuit modules using specialized equipment. The cost is reasonable, usually around a hundred bucks to fix.
If the anti-theft light on the Besturn B50 is flashing, I think the first thing to check is the key issue—it could be a weak battery or a damaged chip. Try using the spare key to see if it works; if not, restart the vehicle a few times. Then check if there are any strong interference sources in the car environment. If that doesn't help, it's recommended to visit a professional shop for further diagnosis, as they have the tools to check if the anti-theft module is faulty. Don't delay too long to prevent the system from locking up and affecting the startup.
