Hey fellows,
The keys have been ordered fabricnew from the national Bentley distributor. The first one once put in, nomore able to put out and the message " immobilizer active " is shown at the same time in the control unit. So it is about to code the immobilizer with the new key. Can anyone of you show me the right working procedure?

EDIT: I just read your visitors message, so you have no original keys/fobs, and you are attempting to access the KESSY module via code "19795" via "codierung II - 11", none of this will work, you need the 4 digit SKC as I explain below, with this 4 digit code, you add the zero and use this 5 digit pin/SKC in "Zugriffsberechtig - 16" aka "security - 16", the you open up "Anpassung - 10" aka "adaptation - 10", BUT, none of this will help you without the SKC as explained below...
END EDIT.
As to your key fob issue, I take it that possibly you are using a translator to post, as I can not follow exactly, such as "fabricnew", and the Ross-Tech VCDS is not shown in English, BUT, from what I think I see as to the Ross-Tech screen is, I dont see the 5 digit SKC = Secret Key Code, the SKC is a 4 digit numeric code that you add the 0/zero in front of to make the 5 digit SKC such as "01234", SO, do you have the SKC, you can NOT retrieve the SKC with Ross-Tech VCDS, you either retrieve the SKC from the KESSY module 93C86 eeprom with Carprog, this will give you the 4 digit code that you add the 0 to the front of, or you retrieve it from the 95040 eeprom in either of the engine ECU'S, this method requires Ponyprog and a chip reader along with a serial port laptop...
Or, you drive or flatbed the vehicle to Bentley so they can hookup to the mothership to program the new fobs to the vehicle KESSY.
What year is your GTC, how many keys do you have, any original keys ?
Another way to retrieve the SKC from OBD port with tools described in the AW thread linked below.
Remember, you take all risk and responsibility, as none of this is guaranteed, I personally have retrieved the SKC via reading the 93C86 eeprom from the KESSY module with Carprog, this did entail removing the 93C86 eeprom/chip from the board for proper reading, I also did the procedure of reading the 95040 chips from the engine ECU'S, I used the Ponyprog SW and serial port chip reader to get the SKC via Hexadecimal to decimal converter, I tested it numerous times, it worked, BUT, I did it by removing the 95040 chip and reading it, NOT via OBD as this procedure on AW shows, I guess I should try it someday to confirm.
