Thanks for the guide.

Should be noted that on newer/older (?) boards, the battery compartment is different, and doesn't have a screw in the middle. Instead a screw is hidden under the little serial number to the side of the battery compartment. there is however no sticker on the middle of the back hiding two screws.

You can also remove the keys, by depressing the two snap-in hooks from the back-side. I had to do this as the stablizer on my enter key (ISO layout) wasn't properly on.

EDIT: Just realized I have a K400 plus. Well those are the only differences, so this guide pretty much applies to that too! :)
