What your saying is basically this:
Get virgin transponders in ALL keys...inc the key flip keys....

Key Matching with 4-digit SKC

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk.
This procedure details
how to match new keys to Immobilizer-equipped VW/Audi vehicles. As of 11 Mar. 2002, VW and Audi are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code) method unless the owner still has the correct 4-digit code.
Note: See this page for important SKC information.
