Unfortunately there is no manual method for that on a VW it all has to be done using a VAG capable scan tool and a security code like a dealer or locksmith has. Then you use the tool to first initialize the key to the transponder then it has to be initialized to the immobilizer. Normally the only thing using the VIN does is to get you a key that is cut to fit the ignition and locks. You can then use it to make another physical key. Then you program both of those in after erasing the old keys that way none of the original keys will still work. Once the key is initialized for both systems everything the key can do should work. I usually suggest an automotive locksmith as they are generally cheaper than the dealer, plus they could cut you a second key and set both up. Just be sure they can actually program in the keys as individual units, some places will do what is known as cloning the key. That process gives you two working keys but in the cars memory they are both seen as a single key, with that you cannot do anything to add a key later as in effect you still only have one key when you need two different keys for the system to work.
