The development of technology has brought convenience, and remote control car keys are one of them. When it comes to the remote control keys of our cars, they are very convenient for us to use. Click before getting into the car, open the door and sit in, saving time and effort. After you get off the car, you press the button and it locks with a click. You don’t even have to turn your head. Isn’t it a bit cool?
But if it suddenly runs out of power, especially if you are in a hurry to use the car, will you be dumbfounded? Maybe everyone has never thought about how long the remote control key can be used, and what are the signs before it is about to run out of power? Today, Lun Gu is here to talk to you about car remote control keys!
How long can a remote control key be used?
It depends on the usage scenario. The battery life is 2-3 years, which varies depending on the model.
The remote control key of our car uses button battery . So how long can it be used? is related to our usage scenario.
General car remote control key battery life is 2-3 years, depending on the model . If our usage habits are not good and the scene may be affected, then may also run out of power after one year of use.
What should I do if my car key suddenly runs out of power?
Don’t worry if it suddenly runs out of power one day. Generally, remote control keys are equipped with a mechanical key, which is either hidden inside or hung on one side.
When the remote control key runs out of power, the mechanical key becomes a lifesaver. Generally, car door locks are on the handle. Some models will hide the lock hole for the sake of appearance, but they are always near the handle.
What are the signs before the remote control key runs out of power?
If our key is about to run out of power, there are still some phenomena that can be felt, so that we can replace it in time.
The remote control distance has become shorter
It used to be 5 or 6 meters to open the door, but now it has to be very close to the car door to respond. It is possible that the key's battery capacity has changed and the voltage has become low, causing the remote control's ability to transmit signals to decline.
occasionally fails, and it takes a few more presses to successfully unlock it.
presses several times when opening the door, but only one of them responds. presses a few more times to successfully unlock it.
The key indicator light is darker than usual
Pay attention to the indicator light on the key.When you press the button, the indicator light is dimmer than usual, or bright and dim, then you'd better prepare to change the battery.
The dashboard of a luxury car directly displays
. If you are a rich friend, the dashboard of his car will tell you directly that if the battery is out, you can just go and replace it. Of course, it is only for the luxury cars of rich friends.
Mistakenly thinking that the key is out of power:
Lungu also wants to remind friends of one of the situations that may be mistaken for the key out of power:
When you find that the car key is malfunctioning, it does not necessarily mean that the key is out of power. The reason, may also be that there is an interference source nearby. Because the key uses electromagnetic waves to send out indication signals, if there is strong magnetic field interference around the parking location, it will also affect the use of the remote control key.
The transmission frequency of most car remote control keys is between 315 MHz and 434 MHz. There are quite a few signal sources with the same frequency in this vicinity, and they will interfere with each other.
Be wary of the signal jammer behavior of criminals
If it is particularly difficult to use in one place, it will be normal in other places. Some car thieves or people who steal things use this principle to build a signal jammer so that your car cannot be locked and they can go get their things.
So in order to make sure nothing goes wrong, Lungu suggests that it is best to subconsciously pull the car door after locking the door.
The above is all what Lun Gu wrote today. If you think it is useful to you or benefits you, please share it with your friends who need it, so that I can help more people!
