ok the mac community seems soft.... nobody spilled BEER on their macbooks? chai, latte, pomegranate juice..... I have a 2008 macbook pro keys were sticky, I sprayed wd40 (dispaces moisture!) into a cup, then using a small q-tip I applied a mostly dry q-tip swipe across the plastic scissor type connector to lube up the moving part, snapped the key back on, voila! also worked for the sticky noisy touchpad too.
