shock sensor=BCM..looks like it is in your door there may be a loose wire there..mine has started doing the same as yours and I have not had time to work on it yet..but that is what my techs are telling me..good luck..

Just noticed something strange today. The previous owner installed an aftermarket deck (Sony) and when the ignition is off and I turn the lights on, the deck powers up. Turn the lights off, the deck shuts down. Maybe this has something to do with my problem. We shall see.

That just means that the head unit (ignition on) is hooked up to the headlight wire. You should really change that to the right wire which would come on with ignition only.
We are talking about the factory keyless entry/alarm right?
Has a aftermarket alarm ever been installed on this car?
Im going to say its the door pin switch (possibly even the trunk). I would replace those before going any further.

Yep, its the stock alarm. If its one of the door or trunk switches wouldnt the interior lights stay on or come on after the doors/hatch is closed? Forgive my ignorance, I'm not that well versed in electronics, gimme a screwdriver and a wrench and I'm fine.

Once the alarm is in "arm" mode it dims the lights untill they go completely off.
I say the door pins because there are only a few things that can set your alarm off.
1. Shock/impact sensor (which you said you already replaced)
2. Door/trunk pin switch (ive seen water/condensation/corrosion short them out in some cases)
3. Low voltage
Which brings me to my next question.
Is there any way you can get a voltage reading right before the alarm goes off?
