Why did my security alarm do this?

[red06]

Guys, last night I was sitting in the viper in my garage, and I wanted to reset my trip meter, I take that it is the black push button next to speedo.Hit it a couple of times and nothing happened, Held it down for a few seconds and Bang, Horn, lights, Woke up everybody. I did not have my key with me so I had to run into the house, run back, and start playing with the lock-unlock buttons on the fob. It stopped, Nothing in my owners manual about this. Any ideas. Thanks

This was my first thought. Were you trying to reset the trip while the keys were in the off position?

Yes, keys were in the house, I read the manual again about the security system and I have a idea, but it is Sun. morning and I do not want to wake up the neighborhood.
I was sitting in the car,feet hanging over the side of the sill, The odometer read miles then showed door locked, I hit the door switch to show door unlocked, door locked to see the display. Manual says system is armed after 45sec.Even with the door open, the hood was up and I wonder if that triggered it?
