I am not in MO. but if i were i would remove the aftermarket alarm and toss it in the garbage for you!!
I was trying to figure out last night if the radio was not factory or the anti theft was not factory.
Me too,, still dont really know.! Says it has a siren, dont think factory had one but not sure......of anything much anymore!
I didn't answer wasn't sure. Thought the same but you know. Good job to you. :-)
No my alarm is factory my radio isnt
It's all a best guess anyway, that's all we can do!
I would use my Tech2 to test the system but it's not fun to have that BS happening.

There was a manufacture recall on the ignition switch for 2003 Malibus. This affects the anti-theft on the cars. We are in the process of the same thing. I HATE that anti-theft!!!
