What is the reason why the van key cannot be turned?

The reason why the van key cannot be turned is that the steering wheel's automatic locking function has been activated. The steering wheel lock is an anti-theft feature of the car, ensuring the vehicle's safety. The solution is to insert the key, step on the brake, and turn the steering wheel left and right. When the steering wheel is locked, it can be slightly rotated. While turning the steering wheel, turn the key to complete the steering wheel unlocking procedure. After the van is turned off, turning the steering wheel left or right or parking the wheels improperly can cause the steering wheel to rotate under force, triggering the steering wheel's self-locking function. The steering lock pin and steering column engage, preventing the steering wheel from turning. At this point, the vehicle's anti-theft system perceives a theft risk, so it locks the steering wheel to achieve the anti-theft function.

I've driven a van for ten years, and this issue is all too common. Most likely, the steering wheel lock is stuck; just turn the steering wheel slightly left and right while turning the key to unlock it. The key itself could also be the problem—if the teeth are severely worn or bent, it might get stuck when inserted. Sometimes, humid weather causes the lock cylinder to rust, leading to this issue; a bit of rust remover spray can fix it. Once, my colleague forgot to put the car in 'P' gear before trying to start it—the key wouldn't turn at all in an automatic transmission car. Honestly, these problems aren't hard to solve. Just maintain the lock cylinder by keeping it clean and avoid being too rough when inserting or removing the key. If none of these methods work, then it might be a faulty ignition switch, and it's time to visit the repair shop for a check-up.

Last time my minivan had the issue where the key just wouldn't turn. First check if the steering wheel isn't locked in position by turning it slightly left and right. If the key has been used for several years, its teeth might be worn down and not aligning properly in the lock. I've also noticed a detail: this happens more often when the car is parked on a slope. Try gently wiggling the key without using excessive force to avoid breaking it inside. Pay special attention in winter, as frozen locks can also cause this—use a hairdryer to warm the keyhole. If you've just washed the car, water might have caused rust inside. If all else fails, getting a new key made is an easy fix, usually costing around twenty bucks.

The key won't turn mostly due to mechanical issues. Steering wheel lock accounts for 80% of cases - try turning the wheel left/right. Second, check key wear, especially old keys with shallow teeth. Third, examine ignition switch aging or internal spring rust. Automatic transmissions must be in P to turn key, manuals need clutch depressed. Emergency fix: Jiggle steering wheel while turning, spray WD-40 to lubricate cylinder. Never force the key - I've seen broken keys stuck requiring $150 tow truck. If none works, replace ignition switch assembly - $50 at local shops.
