To determine the motherboard model of the car remote control, you first need to open the shell of the remote control and remove its battery. On the battery slot or cover of the remote control, information about the motherboard model is usually marked. This information may take the form of a combination of letters, numbers, or symbols with a specific identifier.
If you can't find the information on the battery slot or cover, you can also look at other parts of the remote, such as the printed model number on the back or edge.
In addition, some remote control manufacturers may provide information about the motherboard model in the product manual, so you can check the manual or search for relevant information on the official website.
