How to reset my keyboard?

I have a Lenovo thinkpad and I can't get some of the keys working. I've tried going through ease of access and a few other keyboard settings and haven't found the solution. Backspace capslock t and y won't work. Someone please help meh

You can try uninstalling the driver and rebooting. Windows will re-install it.
Windows Key + R
Type in devmgmt.msc
Press Enter or click OK
Click the + in front of keyboards
Double click "Standard 101/102-key or Microsoft…"
Driver Tab
Uninstall
Reboot

If it still does not work and it is from a spill, let the laptop dry a few days. Bury it in rice.

Look on eBay for a new keyboard for your model.
Look on Youtube for instructions.
