did you check the vin on the new key bag versus the cars vin?
I'm thinking you didn't get the key from us or I would have heard of this already correct?
can she look in the key hole with a flashlight and pick tool to see if maybe there is debris in there that needs to be cleaned out?
confident it is the original door/handle/lock?
maybe the key was cut incorrectly, I've seen it happen once before, the customer had an original key to compare to and noticed the physical cut was incorrect. warrantied no problem.
were both new keys ever compared to each other as far as the blade cut? I'm guessing you ordered one and it didn't work so you got Chrysler to order in another? So did they keep the original new key there to compare with the 2nd key they ordered before handing it over to you?
