Why Can't the Car Key Unlock or Start the Engine?

[LeNoah]

The reason the car key cannot unlock or start the engine is due to the activation of the steering wheel's auto-lock function. Here are additional details: 1. Steering Wheel Lock: The steering wheel lock is a simple anti-theft feature. When the car is turned off, if the steering wheel is turned left or right or if the wheels are not aligned properly, external force can cause the steering wheel to rotate, triggering the auto-lock function. This engages the steering lock pin with the steering column, preventing the steering wheel from turning. Even inserting the key and applying force will not work, as the vehicle's anti-theft system interprets this as a potential theft risk and locks the steering wheel to prevent unauthorized use. 2. Car Key Precautions: Avoid placing smart keys near mobile phones or computers. Keeping smart keys close to mobile phones, laptops (or portable radios) is not advisable. The frequencies emitted by computers and phones can interfere with the smart key, potentially causing it to malfunction in extreme cases. Additionally, prolonged exposure to high-intensity radio waves can lead to excessive battery drain in the smart key.
