Keys on right side of alpha and numerical sections of keyboard not working

We had a blackout recently, and since then my extended USB keyboard in my 2017 iMac has been faulty. The 0 p ; / on the alpha keys (down in a straight line) and the / 9 6 3 keys on the numpad (down in a straight line) are unresponsive.

I've tried running updates, checking that mouse keys is off, slow keys is off, reset the SMC and NVRAM. Nothing has worked. Help!

iMac 27″ 5K, macOS 13.0

Troubleshooting Keyboard Keys:


I. Reset the SMC and NVRAM using and external keyboard...

  • Use An External Keyboard: It doesn't have to be Apple brand. You might need this adapter: USB-C to USB A Adapter - Apple


II. Reinstalling the macOS:

If Software Troubleshooting is of no success, then reinstall the macOS. If you reinstall the macOS, nothing would be deleted. All intended, original files and ppps that came on your macOS would be reinstalled. It’s all about keeping your system files intact.

1. First, Create a Time Machine backup:
