Non-functional keys

[to0]

Hello,

I got an xv6700 for cheap and, not surprisingly, some of the keys on the keyboard are either nonfunctional or close to it. Some keys seem like they don't work, but if I push hard enough, they do work. Others don't work at all, no matter how hard that I push.

My question is: does anyone have any experience with removing keys to clean under them? This has always solved problems like this in the past on other devices that have keyboards. If I just pop a key off, will I be able to pop it back on?
