xcept if you have a strange model of the N620,but every one of such fones have a flex linked keypad plug that enters to a socket at the back part of the pcb,clean both the socket and the plug,then also peel carefully the keypad press from the surface of the keypad and clean.This should solve your problem especially if caused by water.
