1-9 numbers don't work

[jkxxx]

/ WORKS ONLY SOMETIMES 🤯 /

The solutions for my case:
#1

1. Hold the key longer, more than 10 seconds, be patient.

#2

1. Open and enable Accessibility > Keyboard > Accessibility keyboard
2. Select any input area as Browser Address bar or Form
3. Click whole 1-9 Number part through Accessibility keyboard + your Mouse/TouchPad (Do not use keyboard) and also write into the bar/form all the "special characters" as @#$...
4. Then try Keyboard keys
5. Disable and Close the Accessibility keyboard
6. 🎉

had the same issues with a customers macbook today, checked software nothing in software fixed, i swapped touchpad cable, issue persisted, eventually swapped keyboard assembly and everything was working as normal

Tap on the option key 5 times to switch from key controlled cursor to number pad - and vice versa.

An old topic but could be another solution for those who have been still facing same problem.
I had the exact same problem my MBA late14, ..Not typing 1 to 9...Tried all suggested above.
Mine has been solved by simply after unplugging and replugging the battery.

I have MacBook air 2017 (A1466) and I have exactly the same problem. Everything is working fine I mean the 0 too, but the 1-9 numbers stopped work, or working absolutly random. I'cant belive this is a hardware error, more over, becouse it works properly for minutes. Then stop working again. So i think there is a software problem. Anyone has a solution maybe?

Click on the option key 5 times. That should correct it.
