a few weeks ago my smartkey was acting up. it would not open my drivers door but when i touched the drivers rear door it would open all doors. then i noticed that all of a sudden after driving the vehicle when exiting it automatically closed all doors without a touch from me after several seconds. i was amazed and exited at the same time because i did not have to even do anything. after replacing the battery the closing doors function does not work anymore and i am so distraught. what is going on. someone please help because i am due for a schedule c service that is going to cost me an arm and a leg without asking the dealer to figure out what is going on with myut my key????????????
help please.
