Skoda fabia 2003 key coding

Hi There,

I have a skoda fabia which has only one key, and I want a second.

I have borrowed a laptop and cable with VCDS from my work (technical training college) and am a computer technician myself.

I am tempted to try to program a new key.

I have a paper tag that came with the car with lots of numbers on it (presumably the key codes etc)

I wish to buy a pre-cut key with virgin immobiliser chip from ebay

Can someone talk me through the motions of what to do next regarding the SKC and coding up the new one?

Thanks

Alan
