Hello everyone. As the title said, F1 and 1 key is not working, not due to harsh tapping or dirt beneath the keyboard, it just suddenly stop working. I'm not a Tech guy, so I don't know what to do.

Toshiba Laptop
Model: SATELLITE L500-1KK
Product: PSLJTE-00F00PAR
Serial: Y9192859K

Hopefully, this will be fixed.
NOTE: I did copy-pasting for these faulty keys.
