Not sure about key pins, been a while since I saw a gege but they've got some nasty driver pins, that's for sure. The tolerances are pretty high so it could just be that, although I wouldn't be the least bit surprised if it had crazy key pins aswell. You'll get it open mate, keep at it... and if you're not getting anywhere after a while, just scrub it open. They're definately not easy to pick, but if the bitting is nice and regular it should scrub open without too much hassle.
Make sure to post your findings when you get it apart!
