If you can't find the keys. The laptop is still good. You will just have the reformat the hard drive. That means you will need to install windows on a USB drive then go into the bios and make the laptop boot from the USB or press they boot key during boot in order for it to boot from the USB. Then it just wipes the hard drive and reinstalls windows. It's a bit complicated, maybe ask a computer friend to help you, but the laptop is still good.
