MacBook Pro Retina 2013 - is it possible to open the back cover without sticking?

Question

macbook

Buy a 1.2mm pentagonal star screwdriver and unscrew all the screws and open it, blow out the dust and see why the bottom cover clicks/walks a little.
And at the same time, do not be left without a guarantee from the store that sold it to me. That is, do not make any traces.
Is it real? What are the pitfalls?
PS: I already asked, but instead of MacBook Pro Retina 2013 I just wrote MacBook Pro and probably got answers not to my question.

Answer 1

You can open poppies, add memory, change the hard drive - instructions can be found directly on the apple website.
Only now I have the same poppy and also crunches periodically, it seems to me that this is not fixable, although I wonder what it is)

Answer 2

It is also the same beech and also crunches when I take it with one hand on the right side of the lower half of the case with the display open.
At first glance, there are no marks "Vorenly void if remuved" on the case, so this gives hope that it is possible to open it.

Answer 3

It is possible to open. There are no stickers on the bottom cover. But they stand on the battery. And you can't take anything else there. Everything is soldered
