Just talked to a service advisor about remote keyless.
His guess ends up a little different than mine based on the features the truck has.
I do have power windows and door locks, and a feature code for "hard wired remote start"
I do not have a feature code for remote keyless entry. Service advisor's unguaranteed suspicion is that the reciever is probably present, may not have an antenna, and will probably work for remote start from close range and *maybe* work for lock/unlock.
My guess is that feature code for hard wired remote start is part of the PTO prep package and really means hard wired, so you can start/stop the truck from remote PTO controls at a pump or in a bucket or whatever and that if I have them program a part number 68508721AA key, which does show as a possible key for my truck - same fob as Smike has for his - that it should absolutely be able to be cut for the doors and programmed to start the truck and HOPEFULLY to unlock and remote start.
Key programming with them is $82. I did verify that keys are single use, so a used key is useless. They've had relatively good luck with knockoff keys lately, so he did actually suggest going ebay or amazon instead of a $170 Mopar key especially when it's really unknown if it'll work.
I don't know if the Snap-On scanners are able to do key programming on these trucks? There are several listings that include DIY OBD boxes that claim to match the key to the vehicle too. Without any keyless remote going on I'm unsure if I'd have worse luck programming a remote or same... but I rather suspect my truck might not have a receiver.
