What is the reason for the car not starting and making a buzzing sound when turning the key?

[VonAdrian]

Turning the key and hearing a buzzing sound without the car starting is due to the car's battery being dead, which is a very common issue. In this situation, you need to use another car or an external power source to jump-start the battery. More details are as follows: 1. If the car is a manual transmission, you can use the push-start method to start the generator and the vehicle. It is important to note that the push-start method can cause some damage to the engine and clutch. 2. If the vehicle is completely out of power, you will need to connect an external generator to the car's generator. At the same time, attach the battery clamps to the corresponding positive and negative terminals on the battery. Then, turn on the vehicle's power switch to put it in an electrified state. 3. Once the car can start normally, promptly disconnect the external power source to avoid any adverse effects on the car's battery.
