Just to clarify- yes, you can enable the remote start setting with AlfaOBD, but you still need to have the dealer program the new fob with the remote start button on it. Therefore, it’s not absolutely necessary to use AlfaOBD to enable remote start, since the dealer can add the XBM sales code for remote start when they program the fob.
There is a “kit”, and all it consists of is two fobs and the hood latch with it’s wiring. If you already have a connector with wires plugged into your hood latch, then all you need is a fob.
If you’re buying a fob, you might as well get the one that has the remote tailgate release on it also, as they may be able to add that sales code at the same time. The sales code for remote tailgate release is JKR.
@g00fy has a tradesman, and they were able to add it, but I know of another member that has a big horn, and they weren’t able to add it. I suggest before you choose a fob, call the service department at a dealership, and ask them if the sales code JKR is available to add to your VIN. If so, tell them you’d like to schedule an appointment to have sales codes XBM and JKR added, and a fob programmed that you are supplying. Here’s a fob with remote start and tailgate release -

Here’s one with remote start only-

*EDIT* 11/17/20- I would no longer recommend UHS hardware for fobs unless they can guarantee you are getting a brand new one. Multiple reports of members getting refurbished from them, and they won’t program.
