Help me for my laptop has locked keys 8, u, I,j, k and m. And I can't enetr my password and have no access to my computer. Help me please.

1) Try to reboot your laptop a couple of time.
2) Does your laptop have a button that looks all keys? Mine has one for cleaning.
3) Call your laptops maker and ask for help.
4) If all else fails that sadly means that your keys took some damage or it just stopped

Hope you figure it out.
