Type Cover Button Fell Off

[Usro]

One of the button on my type cover pro 1 has fell off.
Can someone tell me how can I fix it? I tried to push it but it doesn't work.

Thanks

I hope that button is not broken. Another person had success popping it back into place, described here: http://www.reddit.com/r/Surface/comments/29kbpz/type_cover_key_fell_off/

Place the loose button where it belongs, and press firmly straight down.
