Why can't the key turn when starting the car?
2 Answers
The reason why the key can't turn when starting the car is due to the automatic steering wheel lock, a feature present in most passenger cars primarily designed for anti-theft purposes. The solution is to first insert the key into the ignition, then turn the steering wheel left and right with your left hand while simultaneously twisting the key with your right hand until the key can turn, indicating successful steering wheel unlocking. Below are the reasons for a car's automatic lock: 1. Reason for automatic lock: The car automatically locks because the steering wheel was turned when removing the key after the last shutdown. 2. Purpose of the lock: The car's security and anti-theft system perceives a risk of theft, prompting it to lock the steering wheel system to prevent vehicle theft.
I've had experience with the key not turning, and it's quite common for the steering wheel to be locked by the anti-theft system. Try gently shaking the steering wheel, both left and right, while turning the key to see if it unlocks. Another possibility is that there's dust or debris stuck in the keyhole—carefully clean it with some force or try blowing into it. For automatic transmission cars, make sure the gear lever is in the Park position; otherwise, the key won't turn at all. Another potential issue is that the key itself is too worn and needs replacement, or the battery is low, affecting the electronic system—sometimes this can appear to be key-related. Never force the key to turn, as this can damage the ignition switch, leading to higher repair costs. During regular maintenance, pay attention to checking the lock cylinder and key condition, and straighten the steering wheel when parking to reduce the chance of locking. If these methods don't work, it's recommended to visit a professional auto repair shop to check for deeper mechanical issues.
