Why can't the car key be turned when starting the car?

[AllieFitz]

When the car key can't be turned while starting the car, it is because the steering wheel lock function is activated, which is part of the car's anti-theft system. How the steering wheel lock function is activated: After the car is turned off, turning the steering wheel from the centered position in one direction (usually to the left) by a certain angle will cause a "click" sound, locking the steering wheel. Phenomena when the steering wheel is locked: In the locked state, the steering wheel cannot be turned, the key cannot be turned, and the car cannot be started, thereby achieving the anti-theft function. How to unlock the steering wheel: Hold the steering wheel with your left hand and gently shake it while simultaneously turning the key with your right hand to unlock it.

I've been driving for many years and have encountered several instances where the key wouldn't turn. The most common reason is the steering wheel locking up—if the wheels aren't straightened after parking, the anti-theft system can jam the key to prevent theft. Don't force the key, as it can easily break or damage the ignition switch. Try gently turning the steering wheel left and right while turning the key, and it usually unlocks. Another possibility is the key itself: it might be too old and worn, have debris stuck in it, or the battery might be low, affecting the steering lock's strength. In short, if this issue arises, don't mess around—take it to a professional repair shop to check the ignition system. Safety first, to avoid any mid-drive accidents. Regular maintenance of the key's condition and wheel position can prevent a lot of trouble.

As a new driver, I was often scared when the key wouldn't turn when I first started driving. That time I parked by the roadside, the key got stuck and wouldn't turn no matter what, which really stressed me out. Later, a friend told me it was probably the steering wheel lock, as the safety mechanism gets triggered when the wheels are crooked. I learned to try unlocking it by slowly turning the wheel, and it really worked! It could also be due to a worn-out key or low car battery. My advice to new drivers facing this situation is not to panic, do a simple self-check, and if that doesn't work, just call for roadside assistance instead of struggling with it. Driving safety is crucial, and these small issues help build experience—it's good to learn some basic car knowledge.

A key that won't turn is often due to issues with the ignition switch or steering wheel lock. Internal jamming in the ignition mechanism, excessive dust accumulation, or an unreleased locking device can prevent the key from turning. Parking with wheels straightened can reduce the chance of locking; keep the key clean and rust-free. If attempting to unlock by turning the steering wheel doesn't work, it might be an electrical fault or a broken switch, requiring professional repair. Address simple issues yourself, but avoid overconfidence.
