How long does the car key fob last, and what are the signs before the battery runs out?
The development of science and technology has brought convenience, and the remote control car key is one of them, when it comes to the remote control key of the car, it is very convenient for us to use it at ordinary times. Press it before getting in the car, pull the door and sit in, saving time and effort. After getting out of the car, press it, click on the lock, and you don't have to turn your head back, isn't it still a little handsome!
But if it suddenly runs out of power, especially if you are in a hurry to use the car, are you dumbfounded? Maybe you haven't thought about how long the remote control key can last, and what are the signs before the power is about to run out? Today, Wheela will talk to you about the car remote control key!
How long does a key fob last?
The battery life is 2-3 years, depending on the model
The key fob in our car is on a coin cell battery. So how long does it last?
Generally, the battery life of the car remote key is 2-3 years, which varies depending on the model. If our usage habits are not good, the scene may have an impact, then it is also possible that there will be no electricity after 1 year.
What should I do if my car key suddenly runs out of battery?
Don't worry if it suddenly runs out of power one day. Generally, the key fob is equipped with a mechanical key, which is either hidden in it or hung on the side. When the key fob dies, the mechanical key becomes a lifesaver. Generally, the door lock is on the handle, and some models will hide the lock hole for the sake of aesthetics, but it is near the handle.
What are the signs before the key fob dies?
If our key is about to run out of battery, there are still some phenomena that can be felt, so that we can replace it in time.
The remote control distance is shortened
It used to be possible to open the door at 5 or 6 meters, but now it has to be very close to the door to react. It may be that the power of the key changes and the voltage is low, which causes the transmitter ability of this remote control to decrease.
Occasionally, it will malfunction, and it will take several more presses to succeed
When opening the door, I pressed it several times, only one of them was responsive, and it was unlocked successfully by pressing it a few more times.
The key indicator is dimmer than usual
Pay attention to the indicator light on the key, when you press the button, the indicator light is dimmer than usual, or it is bright and dim, then you should also be ready to change the battery.
The luxury car dashboard is displayed directly
If you are a friend of a local tyrant, he will tell you directly on the dashboard of his car that you can change it if there is no electricity, of course, it is limited to the luxury car of a local tyrant friend.
If you mistakenly believe that the key is dead:
Watana also wants to remind his friends of one of the situations that could be mistaken for a dead key:
When your car key fails, it's not necessarily the key out of battery, but also a nearby source of interference. Because the key uses electromagnetic waves to send out indication signals, if there is a strong magnetic field around the parking position, it will also affect the use of the remote key.
The transmission frequency of most car remote control keys is between 315 MHz and 434 MHz, and there are still quite a lot of signal sources with the same frequency in this vicinity, which will interfere with each other.
Be wary of signal jammers
If it is particularly bad in one place, it is normal in other places. There are some people who steal cars or steal things, and they use this principle to make a signal jammer, so that your car can't be locked, and he can go and get things. So in order to make sure that nothing goes wrong, Watani recommends subconsciously pulling the door after locking the door.
