Product key

You don't need a product key to download or install a driver, nor does a driver need to be "activated" so I don't know what you are referring to. All drivers are free.

There are many applications which need a product key and/or have to be activated in order to continue using them.
If that's what you mean, buy the software. We don't supply product keys or activation keys here.

You shouldn't need a product key just drivers from the manufacturers website.
