What are the reasons for the old Mazda 6 not making any sound or responding when starting?

The reasons for the old Mazda 6 not making any sound or responding when starting are as follows: Steering wheel lock: Check if the steering wheel is crooked. The steering wheel lock is a normal anti-theft function. This situation occurs because the steering wheel was turned after the car was turned off, and the car's computer assumes a theft attempt, automatically activating the anti-theft function. The solution is to turn the steering wheel while turning the car key to start. Starter damage: The method to determine this is to listen carefully for any slight electromagnetic sound. If such a sound is present, it usually indicates starter damage or a problem with the wiring between the starter and the battery. No antifreeze added: Some car owners add water or low-quality antifreeze to their cars, which can result in the entire water circuit freezing in extremely cold winter conditions, causing the engine to freeze and crack. This leads to the car's water pump being unable to operate, preventing the car from starting and damaging other engine components.
