I am sorry you have had to wait so long for the first contact. Sometimes this happens when the question you ask is not detailed enough or its just hard to address online. Many have viewed your post, but have decided to pass. I will do my best to help you. I have access to many repair sites, so at the least I can provide something to address at least part of your concern if it is not something I can address from memory and experience. I mainly work in the last half of the day 2pm-midnight cst. , so that is when I do all of my responding. Once you get an answer, you will be prompted to rate me. You are rating my help, not the website, or answer. If you feel the need to rate negative, please save the rating so I can try again or find someone whom may be able to help better. Thanks for using our site, we will do all we can to earn your business, again sorry we did not get to you sooner. X Do you still need help?X Is there any more information you can add?X At minimum what do you need to know if I can not address all of your concern? Chris
Yes I still need your help please.
More information: When I arm the security system, I have to disarm the system because it alarms itself (light flashing, horn blowing) without any theft occurrence. This occurs throughout the day and night (especially early mornings hours) when activated. At this present, my vehicle is security system is not armed which means remaining unlocked/ insured.
At a minimum I want to know why this is occurring and what need to done to fix this problem. so I can secure my vechile without waking up in the middle of sleep to deactive the systems for no apparent reason. Thank you.
Is this the factory installed system or an additional aftermarket one?
While your driving do you ever have a false indicator stating a door is open or does the courtesy light come on for no reason?

I am going to let someone more educated on this concern try.
Do you have an idea when I will be contacted by the the individual you are referring my problem to. Please adviss. Thank you.
This is a common problem with Saturns. It is caused by failure of the BCM. The BCM controls operation of the security system, door locks, and lighting controls for the vehicle. When it starts to fail, the symptoms are erratic and intermittent operation of the door locks, alarm, and sometimes the vehicle lighting. Replacing the BCM is the fix for the problem. The new BCM does have to be programmed by a dealer after installation.
