What are the reasons for the car showing locked and unable to start?

[DerekLee]

The reasons for the car showing locked and unable to start are as follows: 1. Low temperature: In winter, the battery's power consumption significantly increases while its capacity decreases in low temperatures, easily leading to insufficient battery power. If the car's starter operates very slowly, it indicates a weak battery. When jump-starting, be sure to pay attention to the positive and negative terminals. 2. High oil viscosity: The higher the oil viscosity, the lower its fluidity, increasing the engine's operating resistance and making cold starts difficult. The solution is to promptly replace the oil used in low temperatures. Car owners must refuel at reputable gas stations and can carry a gauze wrap to filter impurities when refueling outside.
