Nikon d40 18-55mm lens will not auto focus.

What do you mean by "the shutter button won't depress." It physically won't move, or when you push it, it goes down but does not take a picture? The lens may be damaged (not hard to do) or the contacts may still be dirty. It may not be seated all the way. Does the lens release click when you mount the lens onto the camera? Is it a standard or VR lens and is/are the switches fully in one position or the other.
