Depending on the car, you can loosen the fender liner, starting at the top of the wheel, and possible the lower rear of the fender, at the bottom near the rocker section (some are welded, some are not). The liner is often pretty flexible. You may have it fall out. If you're like me, it will fall out and promptly roll somewhere else just as inaccessible.

A long magnet on a telescoping handle should do the trick. Now if it would just work its way back to the same spot it was at when I could see it
