That requires the dealer's scan tool.
I found an Internet site which says how to program the keyless entry remote. But there is an error: this procedure is good for Elantra 2001 to 2003. Elantra 2004 must be programmed by the dealer. http://car.justanswer.com/hyundai/n1kw-program-remote-entry-hyundai-2004
