My keyboard is not working

[account_disabled]

Hi,

I have got a problem , my macbook pro keyboard suddenly stopped working and every time i press anyway it makes sound and turn the touch pad to right click so when i try to click on something it only use the right click i don't know what's wrong.

and when i got to enter the password in login screen the only key is working is "o" and the "q" is erasing the letters?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
