A brief history of the development of remote keys
The first generation: the traditional mechanical key to achieve the basic door switch function.
The second generation: You can press the remote control button to realize the opening and closing function of the door. However, the car needs a mechanical key to operate. The two keys are used together, and they are indispensable and cumbersome.
The third generation: the function of the key and the remote control are combined into one. The opening/closing/car launching is completed by the active button, and the mechanical key is embedded in the remote control key, which is ready for use.
The fourth generation: on the basis of the active button, the passive working mode is added, and the door opening/closing action can be realized without pressing the button, thereby further improving the efficiency and greatly improving the safety performance.
