I replaces both flex, even whole pcb mainboard and problem is always there.
I even try to power up without lcd's then keys working (when is on i connect flex back) i hear sound click when i press button.
Any Solution?

the problem can only be in 3 places, LCD, mainboard or Keyboard Flex, you can start with the mainboard.
Mainboard - (please answer this question carefully) has the board been in any contact with water? If so then your problem is that.
Keyboard Flex - mainly the issue is the connector which gets caught on the hinge, (Known Issue)
LCD, this could be the issue but check the other 2 first.
