I have now taken in my 04 Z 3 times for the same problem. Somehow, the computer of the car stops recognizing the chip in my key and causing the car not to start. It turns over... just doesn't start. They 1st reprogrammed the computer and the keys. They then 2nd changed out the computer and now it's still doing it and I have no idea what they are going to try this time.

Is anyone else or has anyone else had any issue of such? The code the computer brings up is 1615.
