    Looks like I didn't properly translate the VBA text offset with the Power Query offset.

     

    This should work:

    = (DataIn as text) as text =>
let
   asBinary = Binary.FromText(DataIn, BinaryEncoding.Hex),
   numbers = Binary.ToList(asBinary),
   xored = List.Transform({0 .. List.Count(numbers) - 1}, each 
      Number.BitwiseXor(numbers{_}, Character.ToNumber(Text.At(CodeKey, Number.Mod(_ + 1, Text.Length(CodeKey)))))
   ),
   asDecodedBinary = Binary.FromList(xored),
   asText = Text.FromBinary(asDecodedBinary, TextEncoding.Ascii)
in
   asText
