When I took my crossfire in to have looked at by the dealer they said an aftermarket alarm had been put on the car. That is why alarm is going off.
Okay I figure so let's look into this.

First I went back to the people who I bought the car from and they said "what?, no we did nothing to car"

Second I went to the dealer that first sold the car first and they said "Nope we did not install aftermarket alarm".

Third I then went to a car alarm shop; and they said nope no after market alarm is installed, so who is lying here?

In my estimation the dealer who I took car too could not figure out what was wrong so they blamed it on something no one could see (they said alarm was under dashboard and they had to take dash apart to even see the aftermarket alarm).

Is the alarm siren under dash?
