What Causes Car Key Jamming?
2 Answers
Below are the specific reasons for car key jamming: Improper steering wheel angle: After starting the vehicle with the key, the steering wheel automatically unlocks. Sometimes, when parking, the steering wheel is positioned at a certain angle where turning the key to ignite the engine is possible, but unlocking isn't, resulting in the key not turning. You can gently turn the key with your right hand while lightly rotating the steering wheel with your left hand to naturally unlock it. Steering wheel lock: When the car is turned off, if the steering wheel is turned left or right or the wheels aren't straight when parked, any force applied can cause the steering wheel to rotate, triggering the auto-lock function. This causes the steering lock pin and steering column to engage, making the steering wheel immovable. Even inserting the key and applying force won't turn it. This is the vehicle's anti-theft system detecting a potential theft risk, thus locking the steering wheel to serve its anti-theft function.
In my over ten years of driving, I've encountered several instances of key jamming issues, and there are actually quite a few main causes. The accumulation of dust and small particles in the keyhole is the most common one—every time I insert the key, it feels resistant and not smooth at all. Additionally, if the key itself is bent or severely worn, or frequently tugged on from the keychain, it can also lead to jamming. Aging and rust inside the lock cylinder are another issue, especially during the rainy season or in humid environments, where metal components are prone to corrosion and deformation. Insufficient lubrication is another factor—I remember one winter when the key almost wouldn't turn, but after regularly cleaning it with WD-40 spray, it improved significantly. This reminds me to routinely check the condition of my car key, clean the keyhole promptly, and avoid any impact on my travels.
