Hey Loren,
Sorry I'm late. Just saw this after I replaced mine. Yes, it can be replaced, but it depends on how bad you want to replace it. Once you break it down, don't forget to remove that black sticky cover. Then you will see a metal cover with a bunch of grey circles of sealant. Almost look like they sealed the top of a screw head, but it is just sealant. You have to use a putty knife and carefully remove all of the grey sealant circles on the metal cover. Once that is done, you can remove the metal cover. Then you will see the back of the keyboard itself. The keyboard has another 25 little grey sealants, but these you can pretty much just "twang" off with the edge of your putty knife. Then carefully remove the rubbery keyboard. I used super glue "gel" to install the new one. I had five minute epoxy but that lasted five minutes and hardened. (Who'd of thought?). Good luck. I only did it because I was upset that I bought a $20 keyboard from China and waited 3 weeks to receive it. I wasn't going to buy a $100 palmrest/keyboard combo after I spent $20 and waited 3 weeks.
