Hi,
I want to relearn the original keys of an F15 X5.
The BDC was swapped and a aftermarket key was added.
So the security keys of the BDC aint original anymore and so I can not relearn the original keys.

Someone got a clue on how to recover the original dme/bdc security key or the original key/bdc security key?
Except for buying a new BDC at dealer for 1000+ bucks. :tears_of_joy:

I thought I'd try to read an original keys eeprom (so read the key/bdc security key out of the remote) and calculate the original dme/bdc security key with that key.

Is there a tool that can read locked PCF7953VC1900? Atm only got vvdi prog which does not support those.

Maybe KeyServiceTool support reading the eeprom?


Or someone got another clue on how to regain the original BDC security keys?

Thanks guys,
Becks
