I have the viper alarm system but its also a remote start from like 500ish ft away i believe. My dad got it installed at a audio shop and it has a time delay, long enough for the WTS light to go away before it cranks. The alarm system is awesome too because besides the alarm going off, the key also starts beeping real loudly and shows where it was disturbed on the vehicle. Like if someone tried to open my door, it would show that or if they tried to pop my bed cover, it would say so. Real helpful if you don't hear your alarm sometimes or live in a unsafe neighborhood.
