This was sort of weird....I was at my brother's house checking out some pics my dad had taken on a recent trip, and my son comes in and says, "Dad, I think the car is MAD or something....."
So I go out and....the lights are popping up and down and the horn is going off.....
So......for some reason the damned factory alarm decided to go off....but I have NEVER even got it to arm!
I am wondering about intermittent electrical gremlins.....

 

The factory alarm is activated by locking the door with the key. It usually only goes off if the car is unlocked without the key. It doesn't have shock sensors or anything (at least I don't think so).
