MacBook Pro computer

Suddenly today my keyboard on my MacBook Pro is not allowing me to type in my password. It only lets me type 2 letters and all the other keys do not type anything. Does anyone know how to fix this? I have already turned it off and on again a few times. But the same keys do not do anything. Only one key on the top works, and most of the bottom keys starting with Z work to M, but A to L doesn’t work and only P works on the top. Very sad and don’t know what to do? Does anyone have any information on how I could fix my computer before taking it to get repaired? Thank very much
