Klein did use a press-in BB so this is nothing out of the ordinary. Here is a tutorial (with pics) on how to remove the BB.
It does require special tools, so depending on how much they would charge, your LBS would probably be the place to bring it.

I'm not sure on the BB dimensions of the Klein, but if the dimensions permit, you can get a threadless BB to put back in there if need be.
