I assure you it can be done, I ended up just cutting one of my smaller screw drivers down to size in order to remove the screws.
Also, my problem started out exactly like yours. My key stopped returning after ignition, luckily the starter disengages on a Porsche and doesn't keep trying. I'd suggest ordering the part right away. I found better prices than $35.00 in multiple locations even though $35.00 is not expensive for what you save by doing yourself, you may want to look around.
