1. Check the steering wheel: Make sure the steering wheel is unlocked. Sometimes, the steering wheel can lock if it is turned all the way to one side. Try turning the steering wheel slightly to see if this releases the lock.
2. Check the shifter: Make sure the shifter is in the "Park" position. If the shifter is not properly engaged in park, it may prevent the key from turning. Try moving the shifter back and forth between "Park" and "Neutral" to see if this releases the lock.
3. Insert the key and jiggle it. Sometimes, the key can become stuck in the ignition due to wear or debris. Try inserting the key and gently jiggling it back and forth while applying light pressure. You may need to try this several times.
4. Lubricate the lock cylinder: If the ignition lock cylinder is dry or dirty, it may cause the key to become stuck. You can try lubricating the lock cylinder with a graphite lubricant or a penetrating oil. Insert the key and turn it while spraying the lubricant into the lock.
5. Try a spare key: If you have a spare key, try using it to see if the problem is with the key itself. If the spare key works, you may need to have the original key replaced.
6. Check the battery: A weak or dead battery can sometimes cause electrical problems that affect the ignition system. Check the battery and make sure it has enough power. If the battery is weak, try jump-starting the car or charging the battery to see if this resolves the issue.
7. Replace the ignition switch: If none of the above steps work, the ignition switch may be faulty and may need to be replaced. This is a job that is best left to a qualified mechanic.
If you are unable to resolve the issue yourself, it is recommended to have the car inspected by a mechanic to diagnose and fix the problem correctly.
