Why is the key difficult to turn?

[LailaDella]

Key difficulty in turning is caused by steering wheel lock. You can try turning the steering wheel slightly in its original position with one hand while simultaneously turning the key with the other hand until the key can rotate, which will release the locked steering wheel. It's important to note that when encountering a situation where the car key won't turn, avoid forcing it. The steering wheel lock primarily occurs when the steering wheel was turned while removing the key after the last engine shutdown. At this point, the vehicle's security anti-theft system perceives a theft risk, thus locking the steering wheel to prevent vehicle theft. The function of the steering wheel is to convert the force applied by the driver on the steering wheel edge into torque and transmit it to the steering shaft. It mainly consists of a frame, foam, and mounting clips or screw holes corresponding to the driver airbag (DAB).
