She can't login because of this, but I can. Is there any way to fix this if my idea isn't possible?
If this is a PC, just go out and buy a new keyboard; they aren't that expensive.
If you were to actually find a way to re-assign some keys keys, she would have trouble down the line:
1. If she ever needed the re-assigned keys, you wouldn't be able to use it.
2. If she got into the habit of using the re-assigned keys, she wouldn't be able to use a different PC that has a good keyboard.
You can try alt key and number on the ten key keypad and enter the ASCII code number for that A or a or 1 symbol:
1 is alt + 49
A is alt + 65
a is alt + 97
Please specify what computer and, most importantly, what operating system.
Some computers have an on screen keyboard that can be used with either a touch screen or a mouse.
Another option would be to get another keyboard.
plug in a usb keyboard, and then type it in
