Disable A Certain Key In Your Keyboard

November 25th, 2007

The 'Alternate' (Alt) key of my friend's notebook keyboard got stuck. So, when he presses A, the computer accepts it as Alt + A. The immediate solution that I can think, is to disable the key.

I find that it's not hard to disable a key. Here's how to do it:

  1. Download MapKeyboard from download.com (27KB only)
  2. Uncompress it, then open the MapKeyboard.exe (not installation is required)
  3. A virtual key board will show up.
  4. Click on the key that you want to disable. For my case, I click on RAlt to disable right Alt key.
  5. Then at "Remap selected key to:", select "Disabled".
  6. Finally, click "Save layout" and reboot the PC

If you failed to start the program, you will need to install Microsoft .Net Framework 2.0.

I think this can be useful, especially for some gamers who would like to disable the Windows key for you-know-what reason.

Besides disabling a certain key, the program can map keys as well.

Hope you find it useful too.

Nice find. :)
It would definitely help many others like your friend.
By the way, I think it’s safe to recommend your visitors to download Microsoft .NET framework 3, instead of version 2.

Since the program stated that it requires .NET Framework version 2, I’ll just obey to it!

Anyway, I agree with you. I’m quite sure it would work on Version 3 as well.

Ive spilt drink on my laptop and none of them work apart from a few
i think after it gets hot one of my keys just permanently stays on in different patterns (which is Z)
so when I’m trying to type anything lots of z’s come out its annoying as hell!
ill give it a go and see what happens

Thanks for this. On the other hand, is there a way to substitute the press of a key on the keyboard by a signal input on the PC (like an input from a coin validator)?
