What to Do When the Car Key Won't Turn?

The reason the car key won't turn is that the automatic steering wheel lock function has been activated. Here are the relevant details: 1. The steering wheel lock is a car anti-theft feature designed to ensure vehicle safety. The solution is to insert the key, press the brake, and gently turn the steering wheel left and right. When the steering wheel is locked, it can be slightly moved. While turning the steering wheel, turn the key to complete the steering wheel unlocking process. 2. After turning off the engine, if you turn the steering wheel left or right or if the wheels are not aligned when parked, the applied force can cause the steering wheel to turn, triggering the self-locking function. This causes the steering lock pin and steering column to engage, preventing the steering wheel from turning. At this point, the vehicle's anti-theft system perceives a theft risk, thus locking the steering wheel to serve its anti-theft purpose.

Why is there heavy white smoke and strong odor from the car's exhaust pipe?

White smoke from a car's exhaust pipe is generally a normal phenomenon, but if there is a large amount of white smoke, it may indicate that the engine piston is faulty and starting to burn oil. As for the odor, it is usually caused by the release of silicon material inside the catalytic converter when heated, which is normal. However, if the pungent smell becomes increasingly strong, it is recommended to have it inspected and repaired at a service center. Here is more related information: 1. Normal white smoke: Normal white smoke occurs because the exhaust gases coming out of the pipe are at a high temperature, and the high-temperature water vapor rapidly turns into small water droplets in the cooler air, creating "white smoke," which is physically known as liquefaction. If there is a large amount of white smoke, it could be due to damaged engine pistons starting to burn oil. 2. Excessive moisture: If there is too much moisture in the gasoline, it is recommended to clean the throttle body. If the gasoline contains water, check for leaks of water or oil at the junction of the cylinder head and gasket. If leaks are found, it indicates a damaged cylinder gasket causing the leakage. 3. White smoke in low temperatures: White smoke during cold starts is normal and should disappear as the engine warms up. However, if the smoke increases and persists when accelerating, along with a worsening pungent smell, it is advisable to have it inspected and repaired at a 4S shop.
