Here is the scoop. I had a 2005 Crossfire Base Coupe and I took it to Huffines Chrysler in Plano, TX. I had a few things repaired under warranty...flaking paint on console and my alarm siren had begun to make a "cricket on crack" sound. My alarm had worked in the past, and never beeped or chirped when armed or disarmed. I got my car back and I had 3 very soft beeps when armed and 1 soft beep when disarmed. Very Cool...I cannot give the tech's name that worked on my car because I do not know it, but someone at Huffines Chrysler 972-867-6000 knows how to make it work. I do see on my service order that the alarm siren 1028006, FP number 5124443-AA was replaced. I do not know if those numbers will help, but I can confirm that my factory alarm now beeps/chirps when armed and disarmed.

You can search "Factory Alarm" for more discussions. My new SRT6 does not beep when the doors are locked....I am going to try and get the same dealership to change the alarm modual to the part number above and pretend like the one on the car "stopped" beeping and see if they will do it. When the part is replaced with the number above, it will beep when armed and disarmed.
