Not to dis your car, but aside from the kill switch recommendation, the next best way to keep your Challenger from getting stolen is to drive a 5.7L. They're not worth much to thieves and their rate of theft is like 1/5 that of a Hellcat's. Professional thieves make money by unloading them either at chop shops or commissions paid from organizations that end up chopping them for parts. The non-Hellcat parts are budget bin cheap in comparison, so you're not going to get many pros trying to lift 5.7s. An entire parted out 5.7 doesn't sell for as much as a single HC engine/trans crate combo.
I would bet that your chance of being carjacked is a lot higher in a 5.7 than your risk of having it stolen.
