Why does the car key light flash and the car won't start?

[DelDakota]

If the car won't start, it indicates that the car's anti-theft function has been activated, preventing the vehicle from starting. You can tow the vehicle to a 4S shop to deactivate the anti-theft system and reset the password. Here are the reasons why the car won't start: Battery depletion: Forgetting to turn off a certain electrical device for a long time can drain the battery's power. Blocked fuel line: Starting the vehicle requires fuel consumption. When the fuel line is blocked, gasoline cannot be consumed, resulting in the car not starting. Poor ignition system performance: This is more likely to occur in winter when the intake air temperature is low, causing excessive fuel accumulation in the cylinder beyond the ignition limit concentration, leading to failure to start.
