Hello, as in the subject I have a question about reading the immobilizer code in the Opel Corsa B 2000 car. The Delphi program allows me to program these keys again, but the manual does not describe the possibility of reading the code from the working key so as to enter the code and program it again . I only have instructions to enter this code from the service book that I do not have. My device is Multidiag Pro VCI Delphi. Please help
