Hello and welcome to Apple Support Communities, Mnegm77!
I understand some of the keys on your MacBook Pro are not working. I'd be happy to provide information to help you troubleshoot this issue.
Use the steps in the following article: If your Apple keyboard doesn't work
"If only some keys on your wireless, USB, or built-in keyboard work
If some keys on your keyboard work and others don't, try these steps.
Caps Lock key
The Caps Lock key is designed to avoid accidental activation. If the Caps Lock key doesn't turn on with a quick tap, hold the key down for about one second, or until the key's green indicator lights up. Do the same to turn off Caps Lock.
Media Eject key
The media eject key 
has a slight delay to keep it from being used accidentally. Hold down the key until the Media Eject icon appears on your screen.
Other keys
You might have set an option that changes how your keyboard operates. Choose Apple () menu > System Preferences, and then try these tips:
- In the Accessibility pane, click Speech in the left side. If "Speak selected text when the key is pressed" is selected, deselect it or click Change Key to select another key.
- In the Accessibility pane, click Keyboard. Make sure Enable Slow Keys is turned off. If it's on, you have to hold down a key longer than usual before it's recognized.
- In the Accessibility pane, click Mouse & Trackpad. Make sure Enable Mouse Keys is off. If it's on, pressing keys in the numeric keypad moves the pointer instead of entering numbers.
- In the Keyboard pane, click Input Sources. Make sure that the correct keyboard layout is selected.
You can also see your keyboard's current layout on your Mac's display to make sure that you're using the correct layout:
- In System Preferences, click Keyboard, then select "Show keyboard and emoji viewers in menu bar."
- Choose the keyboard icon
in your menu bar, then choose Show Keyboard Viewer. You'll see a graphical representation of your keyboard that highlights the corresponding keys you press on your keyboard."
Thank you for using Apple Support Communities.
Enjoy your day!
