Why can't the ignition key of Nissan X-Trail turn?

[DelDavid]

When the ignition key of a Nissan X-Trail won't turn, many people might think there's a malfunction, but in fact, this is just the self-locking anti-theft feature of the car's steering column. The reasons why the key won't turn are as follows: Moving the steering wheel after removing the key: The cause of this situation is moving the steering wheel after removing the key the last time the engine was turned off. To solve this, simply apply a bit of force while gently wiggling the steering wheel left and right and turning the key at the same time. Principle behind the key not turning: After the key is removed, the mechanism controlled by the key no longer holds the locking pin in place, allowing the pin to pop out under the force of the spring. If the steering wheel is turned at this point, the locking pin will engage tightly with the locking groove on the steering column, making the key unable to turn.
