Why is there no response when turning the key to start the car?

No response when inserting and turning the car key to start could be caused by a drained car battery or issues with the car's ignition system. Here are the relevant explanations: 1. Check the car battery: It's likely that the car battery has been completely discharged. In this case, you'll need to find an external power source for a jump start. If the car can start through jump-starting, it indicates a drained battery. After charging the battery, check its lifespan. 2. Inspect the car's ignition system: Check whether there's power in the live wire entering the ignition switch. If there's power, the ignition switch is functioning normally; if not, the ignition switch is faulty. 3. The car's steering wheel might be accidentally locked: This situation can also prevent the car from starting. In this case, place one hand on the steering wheel while using the other hand to turn the car key back and forth. The car should start quickly. This isn't a malfunction but simply a locked steering wheel.
A few days ago, my car suddenly wouldn't start either. After struggling for a while, I realized it was due to a dead battery. If turning the key gives no response at all, first listen for the clicking sound of the starter. If there's no sound at all, it's most likely a battery issue. If the battery has been used for three or four years, it's time to replace it, especially in winter when it's more prone to losing charge. You can try turning on the headlights to check their brightness; if the lights are dim, it's definitely time for a jump start. It could also be that the key's battery is dead, as many cars now use keyless entry. Other possibilities include a blown fuse, a faulty starter, or the steering wheel being locked and jamming the ignition switch—these are harder to fix on your own. It's recommended to first try jump-starting the car with a friend's help, and if that doesn't work, you'll have to call a tow truck.
If you encounter a situation where the key won't turn, don't panic. Most of the time, it's because the steering wheel is locked. Try turning the steering wheel forcefully while twisting the key to unlock it. If the dashboard remains completely dark after turning the key, it's likely that the battery terminals are loose. Open the hood and check if there's white powder on the two metal posts. Tighten them with a wrench that's been boiled in hot water. The ignition switch itself might also have poor contact—sometimes repeatedly turning the key a dozen or so times can coincidentally start the car. My own car is an older model, and when the starter motor's carbon brushes wear out, it won't respond at all. In such cases, find a rubber mallet and tap the motor housing—it works wonders in emergencies. If you smell burning, cut the power immediately.
