Some car owners reported: Accidentally put the car key in the automatic washing machine and washed it. After taking it out, blow it with the hair dryer for five minutes. It should be fine, right?
If the car key accidentally gets into the water, do not press all the buttons on the car key, completely disassemble the car key by yourself, disassemble all the parts, and then buckle the button battery in the car key. Paper towels absorb all the moisture on these scattered parts, and then wrap these scattered parts with paper towels and put them in a rice bag at home. After 48 hours, take out these scattered parts and reinstall them. The key can be used normally.
The car key has been soaked in water. If the battery has been changed before, you can disassemble the key casing, remove the battery, and then dry it with a hair dryer with cold air or air dry it naturally. If the key still cannot be used by the above methods, then you have to send it to a repair shop or 4S shop for replacement and repair.
The specific operation is as follows:
1. When the car key is flooded, it is actually like the mobile phone is flooded. Do not press the button on it immediately, otherwise the water will quickly seep into the inner layer.
2. If you have changed the battery before, you can disassemble the key shell, remove the battery, and then use a hair dryer to dry it with cold air. Do not use hot air, because the circuit board inside the key is not suitable for heating.
Extended information
The precautions when using the keyless start system are as follows:
1. Do not put it together with electronic devices. Since the smart key uses low-intensity radio waves, it may not work properly in the presence of magnetic fields. Therefore, do not often put smart car keys and mobile phones together, and do not place smart keys near TVs or computers.
Two, don't litter. For the smart key, it is easy to be damaged when it falls to the ground from a high altitude and encounters a violent collision.
3. After the smart car key enters water, it will burn out the internal circuit and cause malfunction. Once water enters the smart key, open the case and lay it flat, dry it with a hair dryer, and then send it to the repair shop for inspection. Do not take the key and shake it vigorously, as it is most likely to cause water to flow to other important circuits, and do not use the remote control to unlock immediately, because this may cause the circuit board to burn out.
4. Do not expose the smart key to high-temperature direct sunlight, such as the dashboard or the hood.
5. Do not put the spare key in the car. Once the smart car key is lost, it not only needs to be rebuilt, but also needs to be re-matched with the computer.
6. do not use the wrong battery. The battery life of the smart car key is about 1 year. Be very careful when changing the battery of the smart car key. Once there is a mistake, the circuit board in the key will burn out.
