i have a 94 SLS w/factory system and the horn blows & lights flash,still trying to figure out how it works though lol:hmm:

If its any comfort, my 96 DeVille does the same thing ... when I open the door the security light blinks in the cluster and it goes away when I start the car or close the door .... I don't know of an alarm that mine has like a horn going off or an audible alarm.... If it does I haven't explored it yet.....
