Porsche Cayenne Remote Key Adaption

Hey, I have one Cayenne and it needs adaptation in remote.
The key which the customer has is ok, the car starts fine, but it does not lock through remote.
I read in another thread it needs teaching the keys again and it asks for three secret codes.
How can I find these codes? If I give here the VIN, is it possible to do it or I will have problem with limited time?
Thanks in advance.
