Hi:

You shouldn't need the product key to reinstall W8.1.

Here is what you can do to reinstall W8.1...

Install W8.1 by creating the Microsoft installation media, using another Windows PC, if yours is not working...You want W8.1 64 bit.

Only if you are asked to enter a product key during the installation process, use this generic key.

This is the generic key for W8.1 'Standard.'

If you had to enter the generic key, manually change the generic product key to the W8.1 key in your PC's BIOS in the PC settings menu.

After you get W8.1 installed, and you had to manually enter the W8.1 generic product key, you will need to run the free utility I zipped up and attached below, that will show you show the W8.1 product key in your PC's BIOS.

I have also zipped up and attached below, the Microsoft tool which hopefully will transfer the ISO file to a DVD or usb flash drive so it is bootable.

Then you can install the available drivers and software from your PC's support page.

Some models come with W8.1 Single Language.  If you cannot activate the installation, use the showkey plus utility to see the W8.1 version of Windows that is installed.

If it shows single language, go back and download the W8.1 single language ISO file instead, install W8.1 SL and it will activate the second time around.

Just in in case you are asked for a product key when you go to install, here is the W8.1 SL generic product key...
