Didn’t need the whole kit as my vehicle was already equipped with everything but the remote and programming codes, but watch out for the shady dealers. All the dealers had to do was program the ECM with the included codes which activates the remote as well as the alarm, if you didn’t already have that feature enabled. They have to call the manufacture to do that with the included code but was still charged almost 400 to do that. The same dealer quoted about 200-250 before arriving and starting the process, but after getting the car in the service center they raised the price.One other weird thing happened as well???? After getting everting activated my fuel economy dropped by almost 2mi. I was getting about 16mpg combined but now it fluctuates between high 13-14mpg.
