Question about Computers & Internet
The first thing to try is to reboot your machine. If this does not help, try th keyboard on another machine. If the problem is repeated, then the problem is likely with the contact under the key. You should be able to gently pry off the top of the key (the visible part that has the @ on it). You can clean the contact with an alcohol soaked q-tip. If this doesn't do it for you, I'd invest in a new key board, as further repair efforts will likely be very tiresome.
Good luck and let me know if this helps!

Keyboards can become dirty after periods of extended use, especially if users commonly eat or smoke near the computer. If a keyboard becomes dirty enough, its performance can be affected. Common problems include dead or stuck keys and repeated characters during typing.
Shut down the computer and detach the keyboard connector before any cleaning procedure. Do not remove or connect a keyboard while the computer is running. Doing so may damage the machine, especially a non-USB based keyboard
For a quick cleaning, turn the keyboard upside down and use a can of compressed air to blow out any foreign matter. Be sure to do this in a location where falling debris can be cleaned up easily. Turn the keyboard upside down and tap on it a few times. You should see a bit of dirt fall out. Change the angle and tap harder to make most of it get out
Clean the sides of the keys with a cotton swab dipped in isopropyl alcohol.
For a more thorough cleaning, remove all of the keys. Do this by gently prying up each key with a small screwdriver or a similar lever. When the keys have been removed, blow out any debris with compressed air. With a moist (but not wet) cloth, lightly swab all surfaces. Do not allow any type of fluid to enter the keyboard.
Clean the individual keys and place them back in the keyboard.
