The DBALL3 is a stand alone remote start that allows a 3x lock option through your existing factory keypad. It has the shortest distance of all the remote start options and is limited by your factory keyless entry range. It's a great solution if distance isn't a priority and you don't want to carry around a second key fob. Available for most (but not all) newer vehicles.
 
Price is installed when added to another remote start option. (Most newer cars also require the addition of the DBALL3 bypass). Installation is an additional $189.99 if 3x lock option is desired. Exclusions to install include BMW, Mini Cooper, Mercedes, Volvo, VW, Porsche, Tesla and Audi.
