The "OEM Remote" here does not mean genuine produced by the original manufacturer. It means that the components, programs, circuit, etc. used in these products are roughly or completely the same as the certified products, and the appearance design and functions are also the same as the original, so it can perfectly replace the genuine products but more lower cost.
Most of these "OEM remote fob" are from Chinese manufacturers
