Is the button stuck in the laptop?

I have a problem: the ß key on my laptop is pretty weird. From the pressure, she feels very different from the others, as if she still had some layer underneath. The upper left diagonal half is much easier to press than the lower right. If I also click on the button at the bottom right, my laptop does not register this and if I press another button with the same strength, it works. How to proceed

Remove the button (DOESN'T WORK IN EVERY LAPTOP, can also end badly), go in, and then try again

Yes, exactly, because I think I have such a persistent PC😬
