You would have to add all the wiring to it, install the locks, take it to the dealer and have them reprogram the BCM(Body Control Module) for keyless entry. That'* the most painful way.
Other way is to get one of the higher end systems that Viper has. This includes remote start, keyless and built in alarm. I highly suggest you stay away from the cheap brands.
IMO, its not worth the time, money or headache of either option. Trade the truck in for the options you want.
