With the continuous development of technology, car keys are becoming more and more advanced today. Previously, car keys were ignition switches mechanical keys, but now car keys have been upgraded to electronic smart keys. Although the car smart key is much more advanced than the ignition switch mechanical key, but the relevant knowledge points about the car smart key many car owners do not understand, today Xiaobian will give you a good talk about the car smart key these things.
Many people do not know what the car smart key is, in fact, the car smart key is what we usually call the keyless entry system. It can not only control the car window and sunroof, but also open the car trunk, which is very convenient to control. When we usually use the car smart key, sometimes the indicator light on the key is dimmed or not bright, which is likely to be because the car key battery is out of power, at this time we need to charge the car key battery in time.
In addition, when the remote control distance of the car smart key becomes closer, it also means that the car key battery is out of power. For example, we can usually remotely control the vehicle at a distance of more than 20 meters from the car, but when the car key is out of power, the remote control distance will be shortened to less than 10 meters. The power of the general car smart key battery can be used for about two to three years, when the smart key appears in the situation just mentioned by the editor, it is necessary to charge the smart key in time.
However, some smart keys cannot be charged, and can only replace the new battery, at this time, you need to use a screwdriver and other things to remove the old battery, and then replace it with a new battery. However, when replacing the battery for the smart key, be careful not to use the wrong battery model, otherwise it is likely to burn the circuit board.
If the car smart key suddenly runs out of power, everyone does not have to panic. Because almost all smart keys will hide mechanical keys, which are specially designed by car manufacturers to prevent smart keys from running out of electricity.
Although the car smart key is very convenient to use, we should pay attention to the following points when using it. First of all, we usually pay attention to the use of car smart keys must not enter the water, because the car smart key and mobile phones belong to electronic products, once the water will cause short circuits, it is easy to damage. If you accidentally enter the water when using the smart key, be sure to dry it immediately, and immediately use a hair dryer to dry the key.
Secondly, when we use the car smart key, it is best not to put it together with electronic products with a magnetic field, because the car smart key uses low-intensity radio waves, if it is placed together with electronic products with a magnetic field, it is likely to interfere with the built-in chip and cause the smart key to not be used normally. In addition, we usually pay attention to not putting the smart key in a high temperature environment when using the car smart key, otherwise it is easy to cause damage to the smart key.
Well, today's relevant knowledge points about the car smart key are here, do you understand it clearly?
