Your better off adding an aftermarket alarm. The best invention is the backup battery alarm. You can add one on to the viper alarm, which I did. That way, if the alarm goes off, and someone is able to disconnect the battery to disable the alarm, a second alarm goes off, and requires a special key to turn off. Aftermarket alarms, like the viper, go off when you pound on the glass, let alone break it.
