We got our car in the spring. Just after we got it, I found out about the siren when I accidentally set it off. Yesterday I am going thru things and when I activated the siren again it sounded more like it was about to blow a bearing or something. Wouldn't scare anyone, except the owner. Researched the forum and the only thing I could find was a battery replacement how to and then it didn't sound like screeching crickets any more. Only reference to improper noises?? So is a battery replacement my solution?, maybe some TLC or do I need a new siren? Thanks for the input.
