Rep Power: 0

I changed my car battery and my stereo is asking me for a code to start working again. Since this is a used car it didn't come with it, and the agency knows nothing about it.

I found this numbers under the hood, do you think they could work to get the code, can anyone help me out?

Have you checked for a sticker on the underside of your fuse box cover?

check in your glove box. if you can't find it, the dealership can let you know if you give them the serial number off the back of the radio.
