Does adjusting the speed controls in Keyboard and Mouse (System Preferences) have any affect?
If not can you plug in a USB keyboard and see if that works OK?

I have no experience of replacing the keyboard on a PowerBook. I'm just concerned that if the problem is happening with all the letters on your keyboard then it may not be the keyboard itself that's to blame.
I would want to be sure that its not another component (maybe in the logic board) before I started spending money. You may get lucky - or you may end up with TWO good keyboards and the same problem! Also I don't know if you've ever opened up an aluminium PowerBook - unlike with the Titanium version you have to take it right apart to get the keyboard out. Good luck.

Yes you right. you maybe right 😟
It possible to not about Keyboard, Let me tell you about the story before it happen.

It was not good to type in year I push key but with no letter "just some time"
and this key problem come after I ride a bicycle with powerbook in my backpack in the rain. I'm all wet, when I came home I saw "few" spot of water drop on the screen then I wait 3 day till it all completely dry to turn on Power.

anyway Is it possible to check by software what wrong with the key or other parts ?

It would be worth running the hardware test from your install CD/DVD. It's not completely infallible, but might just pick up where the problem lies. I'm not sure if this is the support document that is specific to your PowerBook model, but I don't think the process is any different:
