The microchip in my Pacifica Car Key seems be going bad, don't know if anyone else has had this problem and if a new key solve the issue. The panic button and lock/unlock button no longer work. The key starts the car with no problems, but when I turn the car off, some dash board lights remain on, the little engine light, etc Is there another way to turn these lights off, if left on for more than 24 hours my car won't start. I'm willing to suck it up and pay the dealer the $225 for a new key but I just want to make sure that this isn't an indication of another problem.
