If your car won't start in the cold, you may need a new battery. Cold temperatures can reduce a battery's efficiency and reveal existing issues. First, check if the battery terminals are clean and tight. If the battery is more than 3-5 years old, it's often best to replace it. For an immediate fix, you can try jump-starting the car or using a block heater to warm up the engine and battery.
