I Own a 2004 Chevy Malibu Maxx and I need to see if the receiver is still hooked up. It's a used car and I don't know if it's still there. I didn't get any keyless remotes with the purchase. I found an auto shop that does deal with this, but the remotes I got don't seem to be sending a signal. This leads me to believe my receiver might be off. It might not, but I should try to find this out first. Any help would be great. Also any websites that have this kind of information and are easily searchable would be great too. Google does not seem to be too helpful as most of my results are about the remote not the receiver. Thanks for your help
