2008 dodge grand caravan Bad key error message

SOURCE: When I put my key in the ignition of my 2008 dodge

Newer Dodge Vehicles do not have an ignition for a "metal" key. They use the Electronic Key called a FOB with a built in or integrated metal key that is only used to unlock the door. The FOB inserts into a WIN module (Wireless Ignition Module) instead of the normal igition. Reprogramming the vehicle usually does the trick however there has been significant problems with the WIN module and the dealer may have to replace it. The 2010's have a recall on some models. The manual states the keys cannot be reprogrammed. The first and easiest solution might be to try replacing the battery in the FOB (aka key),

Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door
