Among the many trendy electronic devices in the car, the smart key system is very eye-catching. The keyless entry technology brings excellent convenience, and the one-button start brings a full sense of technology, but only from turning the key to pressing the button. This change in action is enough to allow many bosses to spend a lot of money to buy some models that are only equipped with smart key systems. However, the definition and application technology of smart keys are different from each other. How can it be regarded as a smart key system? Is the smart key system safe? Let us first analyze the "keyless entry" part of the smart key system. From traditional keys to smart keys The car keys of any era are used to open the doors and start the engine. As a car with high self-value and a certain degree of danger in use, the key is particularly important. The key to the early car was a metal plate, twist the key to open the door, and twist the key to catch fire. Does not possess any technological type. Later, some manufacturers integrated an identification chip on the key, and they had to go through the double identification of the key and the chip to start the car. Traditional mechanical key Later, with the remote control key, the door lock can be opened or closed at the press of Lao Yuan. The remote control is a wireless signal source, the frequency band is consistent with the vehicle, and the door can be opened or closed by issuing a command. We can compare the command to a sentence and the frequency band to a language. It's like the remote controller saying "sesame open the door" to the vehicle in Mandarin, and then the vehicle opens the door. However, the remote control of the vehicle also takes into account the function of the key. Different car models have different instructions, different brands, and different languages ​​for the frequency band. When the remote control of the other car owner issued the command "Little Bunny Open the Door Obediently" in Cantonese, it naturally cannot match and will not affect our car. 8 Inch Tablet
