At times when the key ignition is turned off and key is no longer in the ignition barrel, if you accidentally rotated the steering wheel as you exit/enter the car, you might hear a click sound which means the steering wheel has been locked.. [ fat thighs ].
That will cause the steering lock and when you re-insert the key again, there will be a problem turning the key to position 1.
Most might use brute force to turn the key to position 1, but this will cause the ignition barrel/tumbler to fail in the long run.
To be able to turn the key smoothly to position 1, you will need to unhinge from the steering lock by wiggling the steering wheel towards the position it was accidentally rotated to.
eg, if it was rotated clockwise by a notch after engine was turned off, rotate a little bit clockwise and hold it at that position while you turn the key to position 1. That will unhinge the steering lock and the key will be able to be turned easily and once it is in position 1, the steering wheel will be freed from the lock position.
Doing this will prolong the key ignition barrel/tumbler lifespan and also prevent the unfortunate occurrence of breaking the key within the barrel.
