I purchased a couple sets, hopefully to keep my Crossfires running when SKREEMS become no longer available. Or get another one running if both keys went missing. Maybe they will just turn out to be expensive door stops...at this point IDK...but I would think there was an avenue open to make these sets work in any car (with programming) which is why they were packaged by Mopar with two keys and a door lock, ign lock, and glove box lock, and SKREEM. ???

ZERACER if you find out anything about this, I'm all ears!
