I purchased my Element used and it had an aftermarket car alarm (I'm pretty sure), on it. It has the chirps that sound like a viper, but I'm not sure. The other day, the key remote stopped working. This would unlock/lock and enable/disable the alarm. The remote has new batteries in it - that I replaced a few months ago and it lights up. I'm thinking it's a fuse problem and I've gone thru the under the hood fuse box and under the dash fuse box. What's the easiest way to figure out which type of alarm I have? I've tried looking for the unit, but I really don't know what I'm lookng for. Any other advice is appreciated as well.
