Last night when I parked my car, it was just fine. This morning when I woke up to start the days busines, my car's neck refused to move The ignition too was stiff.

I wondered what could have happened. I was scared it could be the alternator but on a second thought, I decided to try other option

Then I performed How to Unlock a Toyota Steering Wheel with key and it began moving again

Owners with key-based ignition systems will notice their steering wheel is locked if the steering wheel only moves a few inches and the key won’t turn in the ignition. To unlock the steering wheel, turn the steering wheel from left to right while turning the key in the ignition. This should unlock the wheel and the vehicle should start as normal.
