Two days ago as I was opening my bonnies door, the turn signals started to flash and the car started to scream. And the only way i could turn it off was do disconnect the battery. After i reconnected it, the car started again and went for about 10 min and stopped and so far haven't bothered me again. Any ideas on why, plus i never new there is a factory alarm installed.

Welcome to the world of the SSEi factory alarm. As long as you use your key to unlock the doors, or use the keyless fob, it should disable it. If you roll your driver'* window down and lock the doors with the key or fob, then wait a minute or two, and reach in to MANUALLY unlock the doors (not power unlock, the little slider by the release handle) it should go off.

Isnt it great! My brother did that a while ago with his SSE and he had to call me to shut it off.

I had the same problem with my car, then I noticed that when I unlocked the drivers door with the key it wouldnt unlock all the doors (the power unlock didnt kick in). I beleive the power unlock tells the alarm that the door has been unlocked and to disengage. I had to open the door using the passenger door for awhile until I fixed the drivers door switch.
