tablet stuck in keyboard dock

i spilled some coffee on my tablet/keyboard while not in the dock, i cleaned it as best as i could, nothing is broken everything still works fine, the volume rocker is a bit hard to press now but whatever, the issue is i have 2 of theese one with a broken screen, but it still works fine if i use a mouse/keyboard, and my other one wich is perfictly fine, the problem is the one that is fine is stuck in the keyboard dock, if i had my choice i would much rather the other one be stuck in the dock as it has a broken screen, long story short, how do i get this %#*@ thing unstuck, ive tried taking it appart but to no avail so far, also there is one of those fake sd cards stuck in the sd card slot, and has been sence day one, if i could get help with that aswell that would be &&^&^$^ epic.
