If you go on eBay and find a compatible remote year and function wise, remote start, rear gate, etc. Read through the listings you'll find one with a key that says, WILL NOT WORK WITH PROXIMITY SENSOR, I posted this before. It will solve all your problems as you can just hide it on your Jeep. Everything functions 100% it just is not recognized by the car for entry functions so you can do whatever you like once you lock it the door handles and buttons are inoperative.
I have one under my jeep always and it does nothing till I hit the button. Also unless your dealer is competent you'll want to tell them since they'll likely tell you something is wrong when they try but I guarantee it works.
They're aren't so many that are listed properly year wise, I use the back as the indicator match that and you're golden.
