Hi, I have Town and Country 2012. I replaced the battery, the engine starts Ok but doors can not open with remote. Any idea?

You Chrysler key has two different circuits. One that is powered by your car's igntion system by inducing a current. That is the system that starts the car and doesn't need the batteries to work. The second circuit is used to lock and unlock the car. It can fail. The car may still start. What you can do is go to a place that makes keys or even auto parts stores. They often have key battery tester that check the how strong the signal of the battery is. Test you key. If it doesn't send a signal you have a bad key. If the door lock unlcok works with your other key, then you have confirmed that the key is defective.
