reset maintainence required light

The maintenance required light comes on in less than 10k miles traveled. It is annoying and the dealers will not tell me how to reset it. What are the methods to reset this light? Is there also a way to permanently turn this light off?

i know in my 95 there's a hole right near it in the plastic that you just stick the key into. problem solved?

and i'm not gonna go outside and check, but isn't that just a colored piece of plastic that moves under there? i didn't think it was an actual light.
