How do I remove the air bag center section from the steering wheel

What is your question?

I have a 2006 pontiac with a blown drivers side air bag. I would like to change it out but I've been having a terrible time with this. There are four triangle holes in the back of the steering wheel. I Bought the tool for this removal but i have tried seven ways to sunday to move ANY thing in those triangle holes and I can't get anything to move in there. Any help would be appreciated? Am I supposed to pry outword or inward with the tool? I'm at a real loss. Thanks, Warren in Montana
