Lately, when I leave the car and lock the doors, the emergency lights begin to flash, as if someone were trying to break into the car, and cannot be turned off unless the doors are left unlocked.

The Chrysler dealer did the diagnostic check and there were no discrepancies. The only thing they noted was that the siren doesn't work. They suggested I replace the siren (Part: $400), but they would not say that this would correct the problem.

Any suggestions?
