You do not need to open the unit up - search the forum for buttons in the wrong place or speak to support - it should be easy to do with patience, but read all the advice first - anything related to a recent Elektron should be applicable - these assembly glitches are not uncommon
No, really, it’s way easier than that. All you need is something like a guitar pick and you can quickly remove the buttons.
A simple push is all it needs to put it back in the right place.
