Why can't the car start after the key gets wet?
2 Answers
The reasons why the car cannot start after the key gets wet are as follows: Steering wheel lock: The steering wheel cannot be turned, and the key cannot be twisted either. This is a simple anti-theft feature of the vehicle, which happens to be at the intersection of key unlocking and lock cylinder torque. Just gently turn the steering wheel clockwise (or counterclockwise) and then lightly twist the key to unlock it smoothly. Reminder: When parking, try to straighten the steering wheel before turning off the engine and removing the key. Incorrect gear position: For automatic transmission cars, the gear must be placed in "P" (some cars include "N" gear) to start. Some cars cannot even remove the key if the gear is not in the "P" position. Reminder: Develop a good habit of placing the gear in "P" before turning off the engine. Check the gear position before starting. Car malfunction: If the car still cannot start in the "P" position, or the dashboard shows an abnormal gear position, it is recommended to seek repairs promptly. It could be due to a damaged electronic gear sensor or electro-pneumatic valve.
I've also experienced the issue of a key getting wet before, and it was quite a hassle. Once the key gets wet, the small circuit board inside can short-circuit or rust, especially the remote chip. If water gets in, the signal can't be transmitted, and of course, the car won't recognize the key, making it impossible to start. I've tried using the cool setting of a hairdryer to dry it out, but you have to be careful not to overheat it, or you might damage the components. Taking the key apart, wiping off the water droplets, and then using it can sometimes save it, but if the corrosion is severe, you'll need to get a new one. Remember, there's no need to rush in such situations. First, go to a 4S shop or a repair shop to check the anti-theft system, and avoid any reckless operations. Develop good habits in daily life—don't leave your keys near water, and using a waterproof bag can prevent problems before they occur. The key point is that water can damage electronic devices, so timely and proper handling is essential.
