The consequences of leaving car doors unlocked overnight are: the battery may be depleted, as many areas inside the car are equipped with sensors that are powered by the battery. If the car is not locked, it will not stop working, and more sensors will remain active, consuming more power. Here is some relevant information: After the car is turned off: the power is not completely cut off. Devices such as the anti-theft alarm and warning lights continue to operate. Additionally, many parts of the car have sensors, all of which are powered by the battery. If the car is not locked, it will not enter sleep mode, resulting in more sensors remaining active and consuming more power. Leaving the car doors unlocked after turning off the engine may cause exhaust fumes to accumulate and enter the car through the air intake vents. The car is not completely airtight, and the exhaust gases can seep in through small gaps or holes, leaving unpleasant odors inside the car while also producing many harmful substances and gases. Turn off all devices: Before parking and turning off the engine, make sure to turn off all electrical devices such as lights, air conditioning, reading lights, and windows. Since the engine stops generating electricity after being turned off, closing windows and other electrical devices at that time will overload the battery. Always ensure the car doors are properly closed when locking the car, otherwise, it will increase the car's power consumption. In severe cases, the battery may be completely drained overnight.
