Keyboard has a glitch

[frostydog]

Yesterday our keyboard developed a glitch. When you type on the keys in the "asdf" row every letter is followed by a corresponding number or symbol from the number row. This doesn't seem to be a problem with the keyboard - husband tried it with his laptop and it worked fine. How do I fix this problem?

So you see a1s2d3f4? What about other characters?

System Preferences > Keyboard & Mouse : Keyboard ... Change Keyboard Type

This will walk you through steps to setup the keyboard. Here's what Mac Help says:

When you connect a keyboard that is not immediately recognized, Keyboard Setup Assistant automatically opens so that you can specify the keyboard type (ANSI, JIS, or ISO). There are three keyboard types that Mac OS X recognizes: ISO (Europe), JIS (Japan), and ANSI. The ANSI keyboard is a standard 101-key layout widely used in the U.S., North America, and many other parts of the world.

If you’re having trouble with your keyboard, you may need to specify the type manually. You can use Keyboard & Mouse preferences to open Keyboard Setup Assistant and specify the keyboard type.
