I've been a crimestopper dealer over 10 years and there products have been great , I have the 2015 remote start alarm combo , its been great !

turbo timer issue..
 

do these alarms have the ability to keep the truck running and also keep it secure while in a store for example?

My last one did and I am pretty sure I can do it with my Astrostart as well. It's just a matter of figureing out how, then it would work the same way as if you started it without the key. If you hit the brake pedal without the ignition on it will shut off.
