The reason why the steering wheel isn't locked but the key won't turn: The steering wheel is locked. After the vehicle is turned off, the steering wheel will automatically lock as a simple anti-theft feature. When the vehicle is started with the key, the steering wheel will automatically unlock. However, sometimes when parking, if the steering wheel is positioned at a certain angle where the key can be turned to ignite but not unlock the steering wheel, this phenomenon occurs. You can gently turn the key with your right hand while lightly turning the steering wheel with your left hand, and the steering wheel will naturally unlock. The steering wheel is the wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.
Having driven for so many years, I've often encountered the frustrating issue where the steering wheel isn't locked but the key won't turn. The most common reason is that the steering wheel is slightly stuck on the steering column's locking mechanism—if the wheels hit an obstacle or aren't straightened when parked, the steering wheel can easily get stuck, preventing the key from turning. Another possible issue is dirt or rust inside the lock cylinder, especially in humid weather, where dust or moisture buildup can affect smooth operation. A bent or worn key is also a frequent culprit—I once had an old key that caused the problem, and replacing it fixed the issue. Avoid forcing the key to turn, as this can damage the lock cylinder. Try gently wiggling the steering wheel left and right while slowly turning the key—this often resolves the jam. If that doesn’t work, it’s best to have a mechanic inspect the lock cylinder and apply a specialized lubricant to prevent similar issues. Regular maintenance of the steering system is also crucial.
A few days ago when parking at the mall, my car key suddenly wouldn't turn, though the steering wheel wasn't completely locked, which gave me a scare. Later I learned that even though the steering wheel wasn't fully locked, it might have gotten stuck due to uneven ground or parking position. A friend taught me to first check if the key was deformed - my car key had some wear after three years of use, and trying the spare key worked. Lock cylinder issues are also common, such as dust buildup or aging internal springs. Gently wiggling the steering wheel while slowly turning the key often helps. In cold weather, lock cylinders tend to get stickier - I've used graphite powder spray for simple maintenance. Remember not to force it, as damaging the lock cylinder can be expensive to repair. When parking normally, ensure the steering wheel is centered and straight to avoid uneven wheel stress - this reduces failure chances and protects the steering system. It's recommended to take your car key to a professional shop to assess if replacement is needed.
