I'll respectfully say that you can't always use a pedal wrench. I have this very same problem right now (only way the pedals will come off is with a hex from the inside of the crankarm; there is nowhere to use a pedal wrench). I decided to just take it to the shop and have them do it...that way if anything gets damaged, they have to fix it! I'm still cursing the original shop that built the bike (and cussing at myself too for not noticing it until recently, when I wanted to switch to a lighter pedal).
