With the development of the automotive field, various car companies are more and more complete in terms of car configuration. Nowadays, many high-tech technologies have been used on the car body, which makes the car full of technology. Nowadays, a lot of luxury configurations to buy a car are standard, such as keyless start, this configuration is relatively early, and keyless entry is a new technology. In the face of these configurations, we all know what it is used for, and how it is used, but do you know its principle? In fact, many old drivers don’t understand how these two configurations work. Let’s take a look at the principles of these two configurations today, so that everyone can not only know how to use it but also know its principles.

At the beginning, the control of the car’s lock door and door opening was manually controlled by the key, and later by the key remote control, the state of the door can be controlled by the key on the key. With the rapid development of science and technology, the most advanced now is the keyless entry, which uses the radio frequency technology and the control system of the car.

The specific principle is that there will be a chip in the key, and each chip has an ID, which is the same as the ID on the car, which serves as a matching key. In this way, keyless entry can be achieved. Generally, when you hold the key close to the car, the car will automatically release the closed state of the door, and when the key is kept away from the door, the door can be automatically locked. But its induction is also a certain distance, generally around 1.5m. Many people would like to be able to steal signals during the unlocking process. In fact, it is not possible, because the signal is encrypted every time it is sensed, so it will not be stolen. Currently, such technology will be equipped on high-end cars.

The second configuration is a keyless start, this is still relatively common, the general car will have this configuration. The so-called keyless starter can be started without the need to turn the key and directly through the button inside the car. This function also uses wireless radio technology. When you enter the car, the system inside the car will detect the information of the chip in your key, and then you can start it.

This technique is much more convenient than the traditional one, and this method has been universally deployed in cars.
