1, functional difference. Automobile key remote control assembly is a device to realize automobile remote control and unlocking. It consists of remote control motherboard, battery, buttons, antenna, circuit board, etc. The remote control motherboard is the core part of the key remote control assembly, which is responsible for processing the user's key input and generating the corresponding radio frequency signal, which is used to communicate with the receiving device of the automobile to realize the functions of opening the door and the trunk.
2. Differences in components. The key remote controller assembly includes the remote controller motherboard and other key components. In addition to the main board of the remote controller, there are batteries for providing energy, buttons operated by users, antennas for transmitting and receiving signals, and circuit boards for connecting various components. As the core of the whole system, the remote control motherboard bears the function of signal processing and control.
3. Remote control signal processing. The main board of the remote controller is responsible for analyzing the user's key input and converting it into the corresponding RF signal. These radio frequency signals are transmitted through the antenna, received by the receiving equipment of the car and perform corresponding operations, such as opening the door and opening the trunk. The remote control motherboard needs stable signal sending and receiving ability to ensure the reliability of remote control.
4. Manufacturing and maintenance. The key remote control assembly is usually an accessory produced by an automobile manufacturer or commissioned by a supplier, and the remote control motherboard is one of the important parts. In the manufacturing process, the remote controller motherboard needs to be well matched and integrated with other components. During maintenance, if the remote controller motherboard fails, it may be necessary to replace the entire key remote controller assembly.
