That would be a dead keyboard. Despite your mention of not fixing it, I think you should know that keyboards are generally cheap and easy to replace. In this case, https://www.amazon.com/Replacement-Keyboard-UX330UA-AH54-UX330UA-AH55-UX330UAK/dp/B08LG1SN1V is $35, and replacement would take ... https://www.ifixit.com/Guide/Asus+Zenbook+UX303L+Keyboard+Replacement/53551 35 screws. No, I wouldn't bother fixing this. Attach an external USB keyboard, copy all the data off, wipe the disk and send to electronics recycling. -dsr-
