I used this to replace/reprogram key fobs for a 2019 Dodge Grand Caravan. Worked great and saved me a ton of money. The dealership wanted something like $800 for a new key fob and the programing. This cost me $80. You can have it for $20
I have since sold the van and the fobs went with it, so you would need to order new fobs from somewhere to use this (Amazon).
It should work for 2008-2020 Dodge Grand Caravan, 2008-2016 Chrysler Town and Country, or a VW Routan, and possibly a Jeep or Ram. See the pictures for the type of fob this works with. I would look this up on Amazon to check all the compatibility stuff to ensure it would work with your car. Please match the FCC ID and chip, button etc. information carefully before purchase.
