2003 Hyundai Sonata

I got a new alternator in March 2010. A couple of weeks ago (July), I left my car door open and the battery died. Jumped the battery and everything was okay except the radio never came back on, and I couldn't use my remote door opener. About 400 miles later, my car died. Found out it I needed another new alternator because of the voltage regulator. Got that, but car radio and remote still don't work. Was told that maybe there's a reset code for the radio, but I've never had to do that before. Any thoughts?

Hi margaretcasey,

Thank you for the donation.

Behind the left side of dash in passenger compartment junction block there is a Fuse # 24 ( 10A) that is common for the radio and keyless entry. Check if it is blown.
