What type of keyboard is it? Do the number keys also act as function keys? Perhaps the function key is stuck.

The easiest answer would be, grab a key removal tool & something to blow air like a shop vac or compressed air and just blow the thing out under the numbers, around the switches, or clean the membrane little rubber coating. If that doesn't work it might be time to either solder on a new switch if possible or just buy a new keyboard.
