Different chip manufacturers have different prefixes chip model, as long as the digital portion of the chip can be the same model. Note: We usually do not recommend copying a rolling code chip, because there are many uncertainties when copying a rolling code chip. When copying a rolling code chip remote control, it is not possible to determine whether the remote control chip is an encryption chip.
