So, i'm still new to this thing.. I am wondering what chirps your car does when arming and disarming factory alarm, or locking doors.

WHen i get out, close my door and hit the lock button, my horn beeps twice. When i hit it again, it will then beep once.

WHen it beeps twice, my doors lock, and my LED on the dash flashes,. I assume thats armed?

Why does it beep twice when i hit it the first time, then once after that? Most alarms chirp once when arming a car..

Is this right? What do your cars do?
