I have a 2002 Audi A6 with only one key. It's the switchblade type with a 3-button + panic remote attached in the lower section. I have read numerous posts on this subject, many of them dated years ago. I know the following: The key actually consists of 3 parts, a remote, the laser cut key blade, and an RFID transponder chip which communicates to the car's immobilizer functions.
There is supposed to be a key code (SKC secure key code) and an immobilizer pin number that would make the key replacement an easier task. I have determined that the immobilizer on my car is a immo3 version, which has been described as one with a "rolling" RFID and is reported to require keys which have not previously been linked to another car. The SKC and immobilizer pin no. are purposely made very difficult to determine.
The Audi dealers want 10% of the value of the car just to provide a 2nd switchblade key and a valet key which were originally provided when new. There are locksmiths who can cut laser keys. VW dealerships can cut the blade too. There are internet suppliers of both types of supposedly new keys.
I have found electronic code readers which claim to be able to read the immobilizer PIN number via the OBDII connection. VAG has a web site that appears to be an access point for locksmiths and requires a secure registration. The "Geko" system at the Audi dealership is supposed to be able to link a vehicle OBDII port through the dealers computer to the Audi Factory Database, and allow new key blades to be cut and the RFID synchronized to the immobilizer without ever revealing the SKC or pin number to the operator. Of course they charge a lot for the service and demand that you buy the keys at full price from them.
What if I buy new key blanks and then find a locksmith to laser cut the blades. I may be able to find a shop or locksmith who can download the immob pin # with a code reader device. Now what?? How to I know that the "new" key blanks will have compatible RFID chips for the Immo3 version in my Audi? Maybe if I show up at the Audi dealer with the new keys already cut....? Any help out there would be greatly appreciated.
