If your really worried about it, you can disable the trunk release mechanism on most cars. I have not checked if this is possible on ours but most remote trunk open devices can be disabled mechanically.

I can tell you that the remote trunk release and the alarm are both controlled by the remote accessory control (RAC) module. Your module may be getting flaky.

That makes sense, do you have any idea where this (RAC) is located. I don't suppose if anyone knows if the (RAC) can be diagnosed, I hate just parts swapping. No doubt a dealer only part, I will have to call and find out how much parts swapping will cost me.

Thanks for the tip. Meanwhile anyone who has solved this problem, your experience would save much headache…

If you're referring to the factory system here, that'* not correct: The security system will be armed if the car is locked with a key in the outside lock.

The system will also arm if locked using the inside door switch as long as the door is open at the time. It will arm about 20 seconds after the last door (or trunk lid) is closed.

I think using the key does not arm the system. There is a way to lock the doors without arming the system from the outside, and I think that'* it.

I would try to find one at a junkyard first. Can't think of a good way to do a diagnostic, other than to take the RAC module out for a while and see if it happens.

You're right. I just found that in the manual, page 54:

I know using the key disarms the system. I don't have a fob and the other day I locked the door and closed it. The next day I noticed that I left the window down... ...so I just reached in, unlocked the door an opened it. The alarm went off. I was like, "What the hell?? How do I turn it off??" So I closed the door, locked it with the key, then as soon as I unlocked it with the key, the alarm shut off. Phew!! :?

haha stupid me..when i first bought the car in may i had no idea it had an alarm system...anyways a week later i was in my car working on it when my brother hit the lock button on the key fob that was in my garage...i thought nothing of it and continued about 10 minutes later i went to get out of the car, slid the lock swith to unlock opend the door and HOLY CRAP it has an alarm system!! lol
I remember my moms old 86 park avenue having a factory system in it...it had no keyless entry to turn the system off u had to put the key in and unlock it. ....anyways its nice to know that my car is armed in some way shape or form.
