cheapest fix is a battery isolator switch under the hood..kills the entire car..

You need to find the black push button called the valet button. That is the overide. Get in the car turn the key to IGN as the alarm is going off and then you have either 5 or 10 seconds to push that button once and then 2-5 seconds later the alarm is shut off. To put the car into valet mode which means no alarm at all you put the key to IGN push that button once then pull key out at which point the blue light should turn solid blue.

Or option two is you open a door and hit the lock, then unlock, then lock button again on the remote and the blue led will be solid which means no crazy alarm.

Did your radio go crazy too? Mine does this when it rains and I discoverd that my fuse box was getting wet. I was told I had a leak in the windshield.My lights would come on at night when this happened and run my battery down.

you have water leaking into the fuse box causing a short cicuit , inspect the fuse box's, inside car and in engine compartment and see which one is getting wet , will look rusty, maybe still have some water left in it etc , then find the leak

Sounds like a short in the wiring. Was the body damage in an area where the wiring could have been damaged also? You should take it back to the repair shop and tell them what is happening.

Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!

you need a satelite

there is a TSB (technical service bulletin) on this issue , with directions to install foam weatherstrip to the AIP.(air intake panel) . TSB #06-06-04-048b
