Hi, Bay Boy.
Thank you for visiting Apple Support Communities.
I understand that keys on your wireless keyboard aren't functioning. Here are a couple troubleshooting articles that I would go through for this issue.
Use the Keyboard Viewer to test whether the keyboard keys are responding correctly when they are pressed.
- Choose System Preferences from the Apple menu, then select Language & Text.
- Select Input Sources.
- Select the Keyboard & Character Viewer checkbox.
- Enable the input source for the keyboard layout you're testing by selecting the checkbox next to it.
- Make sure that "Show Input menu in menu bar" is enabled.
- Choose Show Keyboard Viewer from the Input menu in the menu bar.
- The Keyboard Viewer showing the keyboard layout appears on your display.
- Type the key on the keyboard that doesn’t respond and see if the corresponding key highlights on the Keyboard Viewer. If it does, that key is functioning correctly.
Notes:
- If the mouse keys feature in the Universal Access System Preferences pane is enabled, many of the keyboard keys may not respond as expected.
- If issues persist, try starting up your Mac in single-user mode to see whether a software issue is causing the issue.
