Dell XPS 13 ultrabook space bar doesn't go in completely

Dear fellow users,

First, thanks for spending time reading this post. This afternoon, I just tried to take out my space bar to clean inside a little. I did so by simply pulling out the "lid", don't know how you call it.

When I try to put it back, it refuses to come in completely and now it's so hard to press  and use it  (I tried so hard to write this post).This is a photo ofit, before and after I push the lid down. You can see that I can lift the thing up even when I pushed it back in as hard as I could.

Did anybody experience the sameproblem? Do I have togetanother bar or is there any trick to put it back that I don'tknow?

Thankyou! I really do appreciate ite!
