macbook stuck in control key

long story short my macbook air is stuck in the contol key causing the drop down menu to pop up everytime i click the trackpad, also meaning i cant type. now i found a work around where i just put the macbook in sleep then reboot but as soon as i try and type anything on the keyboard it activates the control key. so frustrating, ive never spilled anything on it, its always been in a case etc... anyone have his issue before? if so any solutions?
