hp pavilion x360 convertible14-ba1xx This might get long, TIA for reading! I've used the full device name my system...

Are there other parts still connected underneath the key? Personally I had this issue and there was a pair of little plastic clip parts under the key that had come out of alignment. I prised up a different key to get a look at how they were supposed to work, then was able to realign them, albeit a little bit wonky. Hopefully yours has a similarly easy fix?
