Laiwu’s car keys are dead, the car can’t catch fire and the car can’t start.
In a few words, answer questions, welcome to this issue of car question and answer.
At present, most car keys are intelligent key with electronic remote control and chip operation. Although this thing is not only more convenient to use than traditional mechanical keys, it is also more demanding. But have you ever thought about what to do if the key suddenly loses power and the door can’t be opened and the car can’t be opened? On our car question and answer, some netizens raised this doubt:
First of all, of course, the simplest thing is to find a supermarket or a small shop to buy a button battery and change it quickly, but if you don’t know how to change it, you can watch the video on the text version and learn how to change the key battery, so be prepared! Maybe when it will come in handy!
However, according to Murphy’s Law, life always likes to surprise us. Sometimes, the more we worry about what happens, the more likely it is to happen. If there is no store around, there is nowhere to buy, or if we are in a hurry to drive away and can’t change the battery, it will be embarrassing. Today, I will teach you an emergency trick, so that you can drive away easily when the key is dead.
The key is dead, how to open the door?
First of all, thinking about the car, the first thing to do, of course, is to open the door first. How can I open the door if the car key is dead? It’s very simple. Remote control keys are always equipped with a mechanical key. Generally speaking, the mechanical keys are hidden in the master key. When it is needed, pull it out, then find the keyhole of the car door, and you can open the car door manually.
However, for the sake of beauty, some models add a cover plate above the keyhole. In this case, a mechanical key needs to be inserted into the hole below the cover plate first, and then gently pry it open to see the keyhole.
In addition, there is a special situation that needs to be told to you. Some vehicles’ original car anti-theft systems, the previous generation Qijun and Teana, are equipped with top models of CARWINGS system. If they are not unlocked by the induction key, the vehicles will call the police. Therefore, using the mechanical key to enter the vehicle may be judged by the anti-theft system that the door is abnormally opened and an alarm sounds, but don’t be nervous, and the alarm will be lifted when you get on the bus and start the vehicle.
How to start the vehicle after opening the door?
After opening the door, we can try to start the vehicle directly. If not, don’t be nervous, because at the beginning of designing this function, the manufacturer has already provided an emergency plan and set up a sensing area. As long as the key is placed in the sensing area, the key can start the vehicle even if there is no electricity.
In the video below, I will start the vehicle with intelligent key with the battery removed, and give you an intuitive demonstration of the principle of starting the key without electricity.
As for the specific location of the sensing area, there are many kinds. For example, our Nissan model, this sensing area is at the location where the key is started. We just need to put the key near the start button and then step on the brake. If the light of the start button is on, it proves that the car senses the existence of the key and can start the vehicle.
Other models are set under the steering wheel and in the armrest box. The easiest and most reliable way to know the location of the sensing area of your car is to read the instruction manual, which will clearly introduce where the sensing area is.
Finally, I would like to remind you that in fact, there are signs before the car key is dead. Generally, the battery life of the car key is two to three years. When your car key is locked or unlocked several times, you should pay attention to it, probably because the battery power is not enough.
In addition, like our Nissan model, if the vehicle senses that the remote control key is low in power, the warning light of the intelligent key system on the dashboard will light up to give a prompt. Once the above situation occurs, it is best for everyone to replace the battery in time. Otherwise, if you can’t open the lock and stop the car, you may be in trouble.
