2003 Hyundai Elantra Radio dead

Code will be with owners manual

use a scan tool to reset the ECM first as the CPU program in the ECM may be corrupted from the battery change

Check the fuse. If its okay there may be another fuse behind the unit (inline fuse) more common if the radio was replaced with an after market unit. Also make sure the ground strap on the radio is connected to a solid metal part of the car.

need the chassis number of the radio to generate a code ,or any dealer

did you get your headlight switch checked.

first thing call 765-448-1502 ask for service, they can tell you the code you need for the radio.. its free to the public..be sure to have your vin # ready because they will need it to get the code.. good luck keith...

Sounds like the Antenna, Antenna are cheaper to try. pull out the radio and plug in a universal antenna. see if it works.

the key needs to be re taught to talk to the imobiliser and the radio could be dead check the fuse the good news is dealer warranty is 5 year or 80000 km
