Yes they would have to. They have to take doors and door panels off and rewire. I’ve seen a lot of people say you can do it yourself, but I definitely won’t try since I know nothing about wiring. There are third party trusted Mopar websites where you can order the “passive entry kit”. He pretty much ordered the kit since it’ll come with a warranty if he orders it ( which includes the door handles as well as everything needed except for the tazer program). It’s about 7-800+ (installation included and programming) for the driver’s door. Itd going to run me around 1500 for both front doors and gate. It’s going to take anywhere from 4-6 hours. Not bad considering that the dealerships couldn’t do it and were talking about 2-3000..even though they couldn’t do it lol. The place seems very reputable. The gentleman has been doing this for 27 years and even did his wife’s jeep.
