D Key Not Working After TroubleShooting

Hi Team,

My MacBook’s D key stopped working and I’ve done all the troubleshooting steps I could find on Apple / community guidelines.

Nothing’s worked. I keep my MacBook very clean / tidy, so don’t think it’s down to dirt or dust. Any pointers?

Or should I just head to an Apple Store to have it checked out?

Thanks a bunch!
