You normally do not have to reprogram the key when you replace the battery. If you do you will have to contact your VW dealer.
You'll probably need to have this done at a dealership.

the bastards at the dealership have to do it...had it done, not cheap.
Take it to your dealership they would be the one to help you with that.
your key fob can only be programed by the local gm dealer.
to reset the FOB you get in the car, shut the doors. Then hold the cetral locking lock all button down until the doors lock and unlock. The imobilser light goes solid red. At this point you have 10 seconds to click the new unprogrammed FOB. the doors will unlock and lock. Job done
It can cost as much as about 300 dollars to re-key the average car. This varies depending on the type of ignition and the type of key.
