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

It is because the steering wheel lock is jamming the key. Detailed Explanation: 1. Steering Wheel Lock: Most car steering wheels come with a steering wheel lock function, which is one of the basic anti-theft designs of a vehicle. When the steering wheel is locked, the steering wheel cannot be turned, the key cannot be rotated, and the car cannot be started, thereby achieving the anti-theft function. 2. Locking Mechanism: The locking mechanism of the steering wheel lock works similarly to a door latch. If it is used frequently over time, requiring repeated movement of the steering wheel to unlock, the locking mechanism can become excessively worn or even fail to engage properly, ultimately affecting driving safety. This is especially true for vehicles equipped with engine immobilizers, where the steering wheel locking mechanism is an electronically controlled lock. The electronic lock tongue is more prone to damage when subjected to repeated forceful movements.
Last time my car had the same issue, the key wouldn't turn no matter what and it wouldn't start. I suspect the steering wheel was locked—this often happens if the wheel isn't straightened when parking. Try gently wiggling the steering wheel left and right while slowly turning the key—if it unlocks, then it's no big deal. It could also be that the key itself is severely worn or there's debris stuck in the slot; try taking out the key and cleaning it. The electronic ignition system might also be at fault, such as the anti-theft system being activated or a weak battery—replacing the battery should fix it. Never force it, as you could damage the ignition switch or other components. When parking daily, make sure the steering wheel is straightened before turning off the engine to prevent this minor hassle. If you really can't figure it out, it's best to take it to a professional repair shop for inspection.
