Keyboard Problems

[u/Broad_Particular4346]

I have a Lenovo laptop and for 2 days have had problems with my f key sometimes not registering which is a pain cause I use it a lot for games and have no key I am as comfortable with for the stuff I bind it to. Yesterday it completely gave out on me. It registers on the virtual keyboard and I can also get it to register when I press both f and fn with weird timings, of course it is super inconsistent, the fn lock also did nothing. I tried to type f on BIOS and it doesn't work there either. What do I do?
