Why can't the lock cylinder of Nissan Tiida turn?

When the steering wheel is locked and the key can'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 can't turn are as follows: Moving the steering wheel after removing the key: The cause of this situation is that the steering wheel was moved after the key was removed during the last engine shutdown. In this case, simply applying a little force while gently shaking the steering wheel left and right and turning the key can solve the problem. The principle of why it can't turn: After the key is removed, the mechanism controlled by the key no longer holds the locking pin, and the locking pin pops out under the action of the spring. At this point, if the steering wheel is turned, the locking pin will engage tightly with the locking groove on the steering column, making the key unable to turn as well.
Last time my old Nissan Tiida also encountered the issue of the lock cylinder not turning, which was really frustrating! There could be several reasons: First, the lock cylinder might have rusted, especially during rainy or humid seasons when metal tends to oxidize and get stuck; second, the key might have worn out or deformed over time, making it difficult to insert smoothly; third, there might be dust or small stones stuck inside the door lock. I tried spraying some WD-40 lubricant to loosen it up, but never force it to turn to avoid damaging the lock cylinder. Safety first—if you can't fix it easily yourself, it's best to drive to a nearby repair shop and have a technician check it to avoid compromising the anti-theft function. During regular maintenance, clean the keyhole periodically to extend its lifespan.
My Tiida's lock cylinder had a similar issue before. I think it's most often a problem with the key—either the teeth are worn down or there's dirt buildup, making it hard to insert or remove. It could also be due to aging of the lock cylinder, where metal fatigue causes deformation and jamming. I usually clean the key with a cotton swab dipped in alcohol and spray some lubricant into the keyhole, which generally helps. But if it still won’t turn, don’t force it to avoid damaging more parts—contact a professional repair service immediately, as car locks are crucial for security. Regular minor maintenance on the keyhole can help reduce this issue.
The Tiida's lock cylinder won't turn, usually due to aging or accumulated dirt causing jamming. Avoid forcing it to prevent damage. Try simple methods like spraying lubricant. If ineffective, be sure to visit a professional shop for inspection to ensure driving safety.
