Q,W,E keys not working, MacBook only starts up normally when...

The Q,W & E keys are not working, confirmed with keyboard viewer.

The Macbook Air will only works normally when any 1 of the working keys is pressed at all time, from the bootup. Otherwise, it’ll shut itself down after a few seconds, even during the booting.

I’d removed the flex cable of the keyboard, and cold start works fine.

I’d done SMC,PRAM/NVRAM, but problem still persist.

I’m kind of think it’s the faulty keyboard issue.

But, would like to ask for 2nd thought and possible solution (except changing the keyboard.

The Q, W & E keys all share a common line so you likely had a spill at one point that corroded the wire trace within the keyboard. So yes! You need a new keyboard!

Given the systems age the the amount of work it takes to replace the keyboard alone, I recommend replacing the full upper case shell as being the smarter direction!
