Makes and years
Dodge used it most. The Grand Caravan had one for its whole 2008 to 2020 run, the Challenger from 2008 to 2014, the Charger from 2008 to 2010 and the Durango from 2011 to 2013, plus the Dart and turn-key Journeys. At Jeep it was the Grand Cherokee from 2008 to 2013 and the Commander from 2008 to 2010.
Ram pickups carried one from 2013 to 2018, and the 1500 Classic kept it after the 2019 redesign. Chrysler used it in the Town and Country minivan and on many 300 sedans, and the Chrysler-built Volkswagen Routan shared the minivan's fob family. The JK Wrangler, Liberty and Patriot never had one. A keyless-start trim may carry a look-alike fob that also works from a pocket; that one is priced as a smart key.
How it is programmed
At the vehicle the blade is cut first, by code. The programmer then goes on the diagnostic port, reads the four-digit security PIN from the vehicle on most models, and uses it to open key learning in the wireless ignition node, the module behind the dash slot. The new fobik is seated and its chip enrolled, and on most models the remote buttons come along in the same pass.
Later vehicles, the 1500 Classic among them, may add a security gateway step. A dealer does the same work on its factory scan tool, pulling the PIN by VIN from its own system. What differs is the setup: the fob comes from the parts counter, the service department puts $100 to $180 of labor on the ticket for the enrollment, and with no working fobik a tow, $125 to $200, brings the vehicle in.
What it costs
Fobiks sit on our remote head key row: $165 to $259 at your vehicle, against $300 to $450 at a dealer. Dodge, Jeep and Ram fobiks are $189, where their dealers ask about $350, and a Chrysler or Routan fob is quoted inside the same range once we have the VIN. With no working fobik left, add $60, so $249 for a Dodge, Jeep or Ram.
