I searched around a bit, found a sedan post but wasn't too informative. I'm contemplating about getting a viper remote start alarm (need to hurry cause best buy is fixing the employee discount on them - ****ers). I'm interested in it for the added motion/shock sensors and remote start, but from what I've read it seems it will get rid of the button effect on the handle (06 g35c) and all that, is there a way to have them work them together so that the factory alarm is gone but the viper is unlocked by having the key fob or the viper pager thing in ur pocket and hitting the button on the handle ?

And will remote start still work even if need key fob to turn on?
