electronic anti-theft system defective 406 coupe *SOLVED

[406coupefan]

hi after (and im actually quite sure before my change of the ecu when i broke it) i got the "electronic anti-theft system defective" error in my car.. 406 coupe
so i CANT start the engine i got the left symbol with the key and it wont start.. i just changed bsi and ecu and key fob... all same time still wont start i guess its locked.
any idea to unlock it without to drive to the dealer .. got galletto here it wont connect gives me error0 for data i guess ecu is locked (even the new / used) one.. help anyone?



edit: tryed to find solution in the net for sure ..they say its a battery problem but i put another diesel aside and bypass them still same problem

Here's an idea: I'm not 100% sure the receiver for the immobiliser transponder is part of the BSI. Inside the keyfob is a little microchip akin to a datatag (http://en.wikipedia.org/wiki/RFID), it's not part of the electronics inside the fob but clipped inside the casing. Perhaps you could try your old keyfob.

hey thanks for your idea but im not even quite sure i get you
well here a picture of the "new" key

the 2 left parts (chip and cover) are "new" the fob/key case inc. key is the old key so i basically just changed the chip for the bsi to connect and the cover i think the part you mean is next to the key and therefore in the old part and now already with the "new" key therefor no need to change right? i mean tell me ill try but i think its already changed everything

I'm confused now.

The point is: is the chip in the key programmed to the BSI?

[406coupefan]

haha sorry ! yes it opens and closes normally its the right one programmed for this bsi. i think as mentioned above its locked from before its not the new key... there any fuse or unblocking option?

[steve_earwig]

This is what I mean. I've lost track of which you're using now so try the other one.

DAMN ! !!!!!!!!!!!! YOURE THE BEST steve_earwig!!!
it worked i didnt think you can get of the key but switched it n workin! UP and on again ! already remapped ! !
now im back to the old turbo problem like in the other topic.. but well!

also noticed the windows wont close anymore with the key?!
anyways GOT IT WORKING AGAIN !

THANKS!

[steve_earwig]

Woohoo! That's good news

Perhaps the windows are something that needs turning on in the BSI
