Hi, I bought my wife this car and remote not working. In body ecu is one error b1242. I take back left cover in trunk and I saw that somebody change RF reciver module because there are description by pen on it that come from jankyard. Reciver door control number is 89741-48150. I don't know if it's the right model. I try program remote by procedure by internet but car doesn't confirm by blinks. My question: Is this module can be derived from the second car or I have to buy new? I saw there is eprom microwire probably programed to each car or maybe not. I can check wires from body ecu to reciver but I don't know if this make sense
Best regards
Adam
