How should I approach the super glue that s stuck in my IPhone4S?

I was super gluing my iPhone case back together, its one of the slider backs were it comes in two pieces and you pop the phone into the case then slide the back cover on to seal it, well it was becoming all loose and stuff and wouldn't the case wouldn't lock anymore so I super glued it shut to keep the case in place ( i didn't want to get a new case I really liked this one) anyways as I was super glueing the case a good drop of super glue found its way into my lock key and now the key is stuck. I underestimated the super glue's fluidity I wasn't expecting it to be so liquidy for that long I expected it stay were I applied it but it somehow found its way to drip into the crevasses of my lock key. Now I can't lock my phone manually or take screen shots or pretty much turn my phone off please tell me what I should do I'm really hoping i can get it fixed bc all it's doing is driving me Insain I've tried to scrap it out when it first happens but nothing all I got was some scrap marks so yeah that's my story hope there's a way

Try putting a little but of nail polish remover on a rag and slowly work it into the button on the phone. Make sure not to drown the button in it as that could cause water damage to the phone. Although since its a form of alcohol it will dry up if a little gets under the button but should also break through the super glue.
