If you've had any work done at a shop, take it there. They should be happy to loosen them for you. That's what I did. Or you could take it to the dealership or other shop. Eventually you should invest in a set of craftsman torx bits. I am still waiting for a quote from Slim and Jims tools on a set. I think you may be able to get them at Sears, maybe even K-Mart.
