I just bought a 1997 Subaru Impreza Outback Sport for my first car. The car is in fantastic condition and is in better condition then all the other cars i've looked at in my price range. But, the only problem I have is that all the key holes are sticking. I'm getting the ignition key hole replaced tomorrow but the doors and trunk key holes stick to. Is there a way I can lubricate it or clean it to make them move?
