I found this elsewhere:
I've fixed this by taking the phone apart, finding where the pressure pads are under the button. I glued a small piece of aluminum foil on to where the pressure pad is. Aluminum foil is a good electrical conductor. It's a delicate process. I don't recommend doing this unless you know what you're doing. But if your handset is already dead/useless, give it a try. Put everything back together and the buttons work again.
