This would completly depend on the feature you wanted on your remote start. Price varied depending on the features you have ont he system you run, some standard feature include but not limited to are, one or two way remote, distance required from the FOB, alarm system included or not, manual/auto transmission, extras available are things like wiper activation, windows up/down, lock/unlock. And most importantly towards cost is name brand. Dodge is one of the worst vehicles to install aftermarket remote starters in if you want the lock/unlock system or have a factory installed alarm system. you'll have diodes and resistors to install in the system to make it work.
To try and answer your question without know the answers to those question is simply a guess, so an average system with basic feature can cost you, between $150 - $300 and that amount again to have it installed. If you have never installed a remote start before it can be done but alot can go wrong in a hurry if done improperly. Hope this helps.
