Why Can't the Car Key Be Turned After Insertion?
2 Answers
Here are the main reasons and solutions for why a car key can't be turned after insertion: 1. The car key may not turn due to the automatic steering wheel lock, which is part of the car's anti-theft system. After the vehicle is turned off, the steering lock pin engages with the steering column, preventing the steering wheel from moving. Even with the key inserted, it cannot be turned. 2. When encountering this issue, you can unlock the steering wheel by inserting the mechanical key, pressing the brake pedal, and then gently turning the steering wheel. Although the steering wheel is locked, it can still be slightly moved. While turning the steering wheel, simultaneously turn the key to complete the unlocking procedure, allowing the vehicle to start normally.
There are several reasons why a car key won't turn when inserted, and I've seen quite a few cases over my years of driving. The most common is steering wheel lock activation - when you accidentally turn the steering wheel after turning off the engine, the anti-theft system automatically locks it. You'll need to gently wiggle the steering wheel while attempting to turn the key to unlock it. If that doesn't work, the key might be severely worn down, with its teeth flattened to the point where it can't engage the lock's tumblers properly, especially common with older vehicle keys that have been used for eight to ten years. Additionally, damaged internal components or dust accumulation in the ignition switch can jam the key - never force it as this might break the key or damage the ignition cylinder. Sometimes the anti-theft system malfunctions, such as when the car battery is dead and the security module loses power, preventing the key from turning. Try using the spare key first. If that still doesn't work, for safety reasons, have your vehicle inspected at a repair shop rather than delaying your trip.
