    Passat B6 BKP 2006 Unable to start after trying to add a new key

    Hello everybody.I have a big issue with my Passat b6 BKP engine, year 2006.I am unable to start the engine after I tried to add a new key.I am sure was following the procedure that I found on rossreck website for Passat 3c Immobilizer key matching word by word.After finishing the procedure the car is not able to recognize even the original key.So now I am able only to unlock the car but not to start it.As I try to start the engine the dashboard lights are not coming on, only the small steering wheel light flashes for less than 2 seconds and then the dashboard stays totally dark.I tried again to do the key matching procedure but now I could see that the keys programmed in the car are 0.So it means that even the original key was deleted.I am able to get to section 25-immobilizer,then I go to security aces 16 and the system accepts the pin of the car, but when I go further and try to do any adaptations it says communication error and I am not able to do anything.Please help.Here is the log file:

    I will assume this is the procedure you were following? If so, what was the feedback from the cluster?

    If you now have no matched keys at all, then I don't think there is anything further that can be done with VCDS.

    Randomly came across this post and I have seen something similar so thought I'd post in case anyone comes across something similar (realise it's way too late to assist the OP)

    I had someone who had attempted the same procedure (add a new blank key) which as far as I know is not possible with a B6 Passat CCM (maybe some early ones?)
    He now had zero working keys.

    After a bit of messing around trying to understand what had happened, I took out the CCM and read out the eeprom.
    Using the free KSG tool from dunt.at I opened the eeprom dump and expected to find that it was totally corrupted, or otherwise beyond repair. I was hoping at an outside chance I might be able to copy just the immo data over into a known good CCM eeprom dump...

    What I found was that the 2 original keys (he only had one when he bought the car) were still in the CCM immo data, however they were marked as 'inactive'.
    I think what happens during the immo learning procedure is that initially the keys are not deleted, they are first marked inactive, before new transponders are learnt. At that point the old transponder data is overwritten.
    So all I had to do was to mark the 2 original keys back to 'active' and then write the eeprom back to the CCM and voila! Car was able to be started with the original key!

    With B6/B7 keys, before matching a virgin key will need to be pre-introduced to the CCM. This can be done with an Avdi (or something like that) tool. Only after that can the new key (not virgin anymore) paired with the CCM with the usual procedure.

    Yes I have done this many times, using pre-coded keys.
    However in this case (and possibly in OP's) they didn't have the correct tools but attempted to start the immo learn procedure anyway. This gets them to the first step of marking the old transponders inactive, but they can't progress from there and I think eventually the immo goes into a lockdown of some sort.
