2. Try moving the steering wheel. Sometimes, the steering wheel can become locked, which can prevent the key from turning. Try moving the steering wheel back and forth while turning the key.
3. Check the ignition switch. The ignition switch may be damaged or worn out, which can prevent the key from turning. If you can, try jiggling the ignition switch while turning the key.
4. Use a lubricant. Applying a lubricant to the key and ignition switch may help to loosen it up and allow the key to turn.
5. Call a locksmith. If you are unable to start your vehicle, you may need to call a locksmith. A locksmith will be able to diagnose the problem and get your vehicle started.
