Nowadays, most car keys use remote control keys,
The advantages and disadvantages of the remote control key are also obvious, and the advantage is of course convenience and convenience. The disadvantage is that it is easily damaged and often does not work. What's more, if you accidentally wash your clothes by putting the key in your pocket, it will go straight into the water, which is even worse. Now let's take a look, what to do if the car key gets into the water?
First: Use a hair dryer to dry with cold air, and do not use hot air, because the circuit board inside should not be overheated. You can also put it in a thin, breathable bag and put it in a hygroscopic rice jar.
Second: After the car key gets into the water, wipe the surface first, open the shell if it will be disassembled, take the battery off, and wipe the internal parts with a paper towel with good water absorption.
Third: after the car key enters the water, it is the same as the mobile phone after the water is in the water, do not rush to start the vehicle to determine whether the key can continue to be used, this practice will make the water stains penetrate into the inner layer more quickly.
Fourth: Slowly wipe the internal key contacts and other parts with a relatively high concentration of anhydrous alcohol, then dry, and press the battery back.
The car key still has to be put away, don't leave it in the pants and wash it, sometimes the above method is very useful, but sometimes you can only change it at 4S point. At the same time, the car key gets into the water, don't rush to dispose of the key casually, it is easy to cause further damage.
