My compustar has it as well. Best accessory I bought with my car

turbo timer, locks the doors/arms 30 seconds after I close the door .. its great.
I say skip the accessories and get a clifford or all in one for anybody in the future who reads this ... door locks, arming, hood/trunk pins, optional motion sensor, 2way alarm so you can get a status on the remote if the car is running or not ...
it HAS to be worth the money to upgrade from a standard alarm.
