Starting a car without making noise can be challenging, but there are some tricks you can try. First, turn off all the electronic devices and accessories, such as the radio or the AC. This will reduce the load on the battery and make it easier to start the engine quietly. Second, try turning the key slowly and gently, without applying too much pressure. This will give the engine time to start up smoothly and reduce the noise. Finally, make sure to keep the car in neutral and press the clutch pedal when starting the engine, to avoid any sudden movements or loud noises.
