Wonder Quest - returned 9/29/13

Guess:  I don't know yet but I think from the car key to the engine is a long rod that turns a part of the engine on

Method of research:  online search

Researched answer:  I found out that the car key turns in the ignition and starter relay.  The starter relay is a tiny magnetic switch that collects and electric jolt from the battery when the key is turned.  Then a small gear with teeth interlocks with the car's fly wheel.  The spinning fly wheel turns the crank shaft which turns the engine on.
