I spilled milk on my laptop keyboard?!

I have a Lenovo ideapad 100-15ibd, and I spilled milk on the right side of my laptop keyboard. The keyboard worked fine and like two hours later, some keys won't work. The list of keys are:

Spacebar
B
N
3 ( Numpad)
Backspace
Enter
RShift
Down arrow key
Left arrow key
Right arrow key
/
.
,
Touchpad

I left it overnight hoping it would dry, but I got the same results.
I used a card then proceeded to put it on the touchpad where some milk has become "plastic".
The touchpad was fixed but the other keys won't.
I have no idea how to detach the keyboard from the laptop since I just bought it.
I am scared that my laptop won't work after a few days,weeks, how do I fix this?
If I am missing any information, please ask me.
