If I were you. I'd look into the newest Viper alarms, with the 2 way transponder. It'll page you when your alarm is tripped, for warnings or the full alarm. It's a very efficient alarm, and you can use the top version alarm on up to 4 different cars...it's weird, go to the viper website and read up on it. I had mine installed last summer, and it's a real stress relief when I park the car for the night
