anti theft system/security system

What is your question?

is there anyway to completely get rid of it on my vehicle? if u unhook the battery the radio locks up until u get a code from the dealership, its affecting my door locks, and i am worried that even tho i found the fuse that runs it ill lock the whole car up if i just pull it out... i only ask cuz the cars previous owner had an amp, w a giant cable w a big fuseable linkage running under my floorboard & i want to take it off but cant unhook the battery w/o messing the radio up. i have the code its just a sob TO DO EVERYTIME
