How long does it take Apple to fix a keyboard on MacBook pro during COVID-19?

Because the keyboard on my Mac has issues, sometimes I cannot turn on the computer on time, because I cannot type the password on my Mac. Even I have a wireless keyboard, sometimes it cannot be connected to the computer by bluetooth; in the last two to three weeks, neither of these two keyboards stopped working and connecting to my mac for at least twice, when I tried to work on something. Every time, when I could not type the password to get into my mac, I would spend around one hour to fix the keyboards. As a college student who is now in summer school, I have to type essays and take exams on the computer, especially during the time of covid-19. How long would it take Apple to replace a keyboard during this specific moment. I don't want that any unexpected thing take places when I take my final exam.
