Curve 8330 keys stopped working

I took my phone out of my pocket on Saturday and not a single one of the keys worked. The keypad, trackball, side keys, etc. all aren't responding. I haven't dropped it or gotten it wet or anything. If I plug it in to my computer I can see the screen light up and see that I have full battery, yet none of the keys work to select anything. I have tried taking the battery out and rebooting it more times than I can even count.  Nothing so far has worked. Any ideas? I don't want to have to get a new phone yet!

And you're not getting any kind of message on the screen? Like device is locked? How long do you leave the battery out when you pull it? Try keeping it out at least a minute
