Why does the car key sometimes not turn?
2 Answers
The reason why the car key sometimes does not turn is: the steering wheel is automatically locked or the automatic transmission is not fully returned to the P position. The purpose of the steering wheel lock is anti-theft. The solution is to first insert the key into the keyhole, turn the steering wheel left and right with your left hand while turning the key with your right hand until the key can be turned. If the gear is not returned, the solution is to start the car, shift the gear again, and make sure it is completely returned. The working principle of the car key is that the key first emits a weak electric wave, which is received by the car antenna. The electronic control unit identifies the signal code, and then the actuator of the system performs the action of opening and closing the lock.
A few days ago I also encountered the issue of the key not turning. A common reason is the steering wheel lock being engaged, especially if the steering wheel was turned too hard when parking, triggering the anti-theft lock. Try gently wiggling the steering wheel left and right while turning the key—this usually works. Another possibility is the key itself being worn or bent, making it hard to insert into the lock cylinder. Try using a spare key. If there’s dust buildup or dryness inside the lock cylinder, applying specialized graphite powder can help, but avoid using oil as it can clog things up. For smart keys, low battery levels might cause unstable signals, preventing the key from turning—replacing the battery should fix it. With over 30 years of driving experience, my advice is not to force it, as you risk breaking the key or damaging the ignition switch, leading to bigger problems. Instead, visit a repair shop for cleaning or replacement parts—simple maintenance can save you major headaches. Regularly check the steering wheel position and key condition to develop good habits and avoid issues.
