How to lock and unlock keyboard in Ubuntu ?

xtrlock might be what you're looking for. It disables the keyboard until you type your password. It does also disable the mouse, but you might be able to change that in the config. Install it by running sudo apt-get install xtrlock.

  it works but It lock both keyboard and mouse. Is there any way to lock only keyboard not cursor so that I can scroll and click ?

  I'm not sure. You can look in the config files (probably somewhere under ~/.config).

  possible duplicate of How to disable and enable keyboard in ubuntu? Read it if you want to disable only keyboard.

  @Ron the problem with that is the keyboard is completely disabled for a certain amount of time. It's not a switch

It doesn't look like there's something that'll lock only the keyboard. You can make two scripts, one to disable the keyboard and one to enable it, but you'd have to make desktop files to run those scripts. It would be a hassle to do this. I could help though. I won't be here for about 2 hours though.
