Why does the alarm go off at random?
I recently put a battery in the car and every now & then the alarm goes off for no reason? It also goes off sometimes when I open the drivers door on occasion?
Why?
Thanks.

From personal experience, I don't think anybody can answer that question, (gremlins). For that reason I would suggest jumping the factory controller and removing something that can at some point strand you. Not to mention a silly alarm that is more of a PIA than a deterrent.

I would start by cleaning all 4 of the trigger switches 2 door pin switches one in the hatch and the other under the hood

Factory.

Any documentation on how to bypass that controller without causing any problems?

...especially easy to ck the under hood switch. It should solidly contact the receiving steel pad. If the pad is missing (unscrewed/removed) or the head of the pin (big black plastic piece) is compromised, it will limit the pin compression and cause intermittent alarm trigger...depending on how well the hood hinges compress.
My encounter: After swapping a hood w/out noticing the missing alarm pin switch receiving pad, the alarm would trigger every once in a while for no apparent reason. I checked all the pins and narrowed it down to the hood, since it was the only known variable (before/after). After inspecting the pin and wires, I'd close the hood and the alarm would be fine for a couple days or so. Repeated head to wall bang exercise for a week. Problem is I kept looking down at the pin/wiring/etc and never UP at the pad...which was missing.
Each time I'd close the hood after inspection and ensure the hinges compressed properly for alignment, the pin would get compressed enough. After vibrating for a couple days, the hinges would settle slightly less compressed than when I last closed the hood and "bing" the pin switch would get releived enough to trigger the alarm.
talk about feeling stupid !!

Try disconnecting the hood pin switch and see if the issues goes away - if yes fix the switch or simply leave it disconnected.
The alarm is designed to go off when you open/unlock a door if it is armed.. so the question is: is it staying armed when you think it should be disarmed? if so it may indicate poor connections in the door key alarm contacts... not disarming as expected...
The other likely candidate is the rear hatch pin switch (but this will usually put the interior lights on...)
If the battery charge gets very low the alarm can do wierd things.

Sheesh ... my central locking was all hosed up and disconnecting the alarm was the fix. Something about an alarm horn hidden in some location where it's almost impossible to replace ...
Good riddance

I had this problem, ended up being the hatch alarm switch. I just disconnected it. I can count on zero hands the number of times I would be worried about someone crowbaring open the trunk when the thief would probably just break the window...
