I just bought a 2008 Elantra (11000 miles) and I have some questions. There appears to be a sensor in the middle of the dashboard. It looks like the sensor that my 2001 Prizm used to turn on the headlights when it got dark. The lights don't turn on automatically so what is the sensor for? The car does not have daytime running lights either - I thought it was required of all new cars. Also, I know the key has a chip that is required for the engine to start. Is this also required to operate the door lock? I tried to have a spare key "cut" and it won't work even though it looks identical.
