If you are unable to type letters, numbers, or symbols, you may have Mouse Keys enabled on a keyboard that has no numeric keypad or Num Lock key.
It happen to me this week, I was entering a password which had numerical numbers and I was using the numerical pad on the right side of my keyboard and I kept getting the wrong password message. I used the numbers above the letters on the keyboard and they worked.
So I thought I had a bad keyboard, until I did a simple search and there it was at Apple support, "Unable to type while Mouse Keys is enabled in Mac OS X" posted December 05, 2011.
Seams like I wasn't the only one having this problem.
Quick fix:
Note: If you are logged on to a user where Mouse Keys is already disabled, but your keyboard is not responding properly, toggle the radio buttons for Mouse Keys "On" then "Off" to restore normal functionality.

Quick fix:
- Choose System Preferences from the Apple menu.
- Choose Universal Access from the View menu.
- Click the Mouse tab or in Lion Click Mouse & Trackpad
- Click Off, next to Mouse Keys. If you have already logged in as a different user where Mouse Keys is disabled, click On and then click Off next to Mouse Keys, to return the keyboard to normal operation.
Note: You may also check/uncheck the box for "Press Option key five times to turn Mouse Keys on or off".
Note: If you are logged on to a user where Mouse Keys is already disabled, but your keyboard is not responding properly, toggle the radio buttons for Mouse Keys "On" then "Off" to restore normal functionality.
