Why can't the ignition key be turned?

It should be caused by the steering wheel lock. When the car key is inserted, the vehicle cannot be started. Here is the relevant information: 1. Steering wheel lock: After parking, turning off the engine, and pulling out the key, if the steering wheel is rolled again, the steering lock and steering column will automatically engage, thereby locking the steering wheel. Just continue to turn the steering wheel a little in its original position while turning the key, and the locked steering wheel can be released. 2. Principle: The principle is that the rotation of the key controls a steel pin through a spring. After the key is pulled out, as long as the steering wheel is turned, the steel pin will pop into a pre-drilled hole and then lock the steering wheel to ensure that it cannot be turned. When the steering wheel is locked, the steering wheel cannot be turned, the key cannot be turned, and the car cannot be started, thereby achieving anti-theft.

This issue is quite common. Suddenly, the ignition key won't turn, which can be a bit alarming. Most likely, the steering wheel is locked—this happens when the wheel isn't straightened after parking, triggering the anti-theft feature. Try gently rocking the steering wheel left and right while slowly turning the key; this usually unlocks it. If that doesn’t work, accumulated dust in the keyhole or severe key wear could also cause it to jam, especially in humid weather or after long periods without cleaning. Another possibility is that the car isn’t in Park (P), as automatic transmissions often lock the key in other gears. Avoid forcing the key, as this could cause more damage. It’s a good idea to keep some keyhole cleaning spray handy for occasional maintenance. For a long-term fix, it’s best to visit a repair shop to check the ignition switch or electronic system—last time, it cost me 200 yuan to fix, and now driving feels much more reassuring.

The ignition key getting stuck and not turning is usually caused by several mechanical or electronic issues. Firstly, the steering wheel lock is the most common cause—when parking, if the steering isn't returned to its neutral position, the system locks. Simply jiggling the steering wheel can unlock it. Secondly, foreign objects like small dust particles or grease buildup inside the keyhole can hinder the key's rotation, which can be resolved by blowing compressed air or applying lubricant. Thirdly, the key itself might be worn or bent, making it difficult to insert at the correct angle, causing it to touch the keyhole wall and get stuck. Additionally, internal wear of the ignition switch or activation of the anti-theft system can also lock the key. Check if the gear shift lever is in the P position, as electronic system malfunctions often occur in such cases. Be cautious when handling these issues yourself, as improper operations may damage components. It's best to seek professional diagnosis early to avoid roadside breakdowns.

Don't panic if the key won't turn, first perform simple checks: Gently wiggle the steering wheel to release the steering lock; If the key won't insert or gets stuck, check for dust in the keyhole - clean with cotton swabs or use compressed air; Make sure the gearshift is in Park. If still not working, it might be key wear or internal ignition switch failure - avoid forcing it to prevent key breakage. You can find online tutorials to lubricate the keyhole yourself, but mistakes are common. Sometimes car anti-theft systems may accidentally lock the ignition. For safety, it's best to visit a mechanic ASAP - they can quickly diagnose with proper tools. Small issues left unattended often cost more later (I've experienced this firsthand).
