Samsung Transform Ultra

I was in love with this phone when I got it. I have had it about six months and it did everything it was supposed to. Last week sometime my power button decided to stop working. This means I can not manually lock my phone and I have to take the battery out to turn it off. Today my options screen started popping up when I close the phone or open it like I have tried to push the power button. This is really frustrating me. I would love to have my phone working again. Any one have any ideas? I have done the factory reset and updates and all of that. I'm wondering if it is possible to open it up and see if something may be under the button or something.
