2 Answers
The causes of steering column lock failure include the following: 1. Low voltage. 2. The steering column lock is not opened. 3. The control key signal is not recognized by the system. 4. The steering column lock cannot be unlocked. 5. Caused by a steering column failure. Here is a detailed introduction to the steering column: 1. The steering column lock is a type of steering column locking device. 2. A key switch module that can generate a detection signal when the car key or portable terminal is inserted or removed. 3. An owner authentication module that can perform authentication steps for the inserted or removed car key or portable terminal based on the detection signal from the aforementioned key switch module. 4. A locking plate that physically restricts the rotational movement of the steering shaft. 5. The steering lock mainly consists of a lock rod, camshaft, lock stopper, unlock lever, and unlock button.
Steering column lock failure is something I've encountered quite a few times. It's a critical part of the vehicle's anti-theft system. Once it malfunctions, the steering wheel won't turn, or even the car won't start. The most common causes are electronic-related, such as a blown fuse—open the fuse box and check the corresponding small square component; when it burns out, the power signal is cut off. Issues with sensors or key recognition are also common, especially when the battery is weak and the signal isn't strong enough. Mechanical jamming can also occur, such as rust in the lock cylinder due to prolonged disuse. My suggestion is to start with the simplest checks: try replacing the key's battery. If that doesn't work, disconnect the battery's negative terminal for a few minutes to reset the system, or gently shake the steering wheel to see if it unlocks. Never force it, as this can easily scratch the column or damage the motor. If the problem persists, seek professional help at a repair shop immediately to avoid travel delays. For regular maintenance, pay attention to periodic cleaning of electronic contact points to reduce issues caused by moisture and dust buildup.
