    If i remember right you need a transponder on Crypto mode. Change on page 3 the 2 first digit. Now is 06. You need to make it 0E.
    try it!!

    Hi all,
    For a scenic 2 (PCF7947) (3 button card) can someone give the codes to precode (I can use the codes from post 9?) but I need also the REMOTE part.

    I can confirm, for a scenic 2/megane 2, 3 button key card, you have to write at line 6 (USER 2) the code A1 01 0F 07 (given by COOLSODA and TERMINATOR1000) and than when I read again the PCF I found at line 6 (RCF) from REMOTE part the code A1 01 0F 07 (Maybe I could write it directly to the RCF line from the remote part but I didn't tried).
    See original china PCF 7947 and the same PCF after precoding

    I used a ZED BULL MINI clone to precode the PCF and than a CLIP Clone to write it to the car and now everything works remote and engine start.
    Thank you all for your help
