So battery on my key recently died and replaced, after that keyless entry doesn't work no more, 2006 GT with smart card key, buttons on the key still works just little rubber button on the door handle won't response what so ever... I read some reprogram topics find out regular reprogram won't work on chip keys.. Need some help, I know dealer would ask some buck out of my bucket, trying to figure it out so I don't have to make the visit...
