Default key and remote - help

I just bought a used 04 A6 3.0 quatro -- that only came with the valet key and emergency plastic key - and no remote!. If I buy a uncut FOB can I program it without having another remote? Does anyone know what the likely FCC ID and mhz is for this vehicle? I'd rather not have to go to the dealer.

Would these instructions work or do I need another remote to do it this way?

1. Take one key and insert it into the ignition. Turn it one click forward.

2. Roll down your window just in case. Step outside the car, and manually lock the car with the key you want reprogramed, ie put the key in the keyhole and turn to lock. Leave the key in the lock

3. Now press the unlock button on the key in the lock. The lights should flash.

4. Now press the lock button on key fob, and then unlock it again.

5. Remove the key from the lock and the key from the ignition, and try it's function.

04 will have an immobilizer so you have to have it done at the dealer. It is not something you can do yourself.
