The factory default code is stored in the ECU and can be retrieved with a high-end OBD scanner

350

It's on the left trunk hinge inside trunk

1,205

It's not in the trunk on mine, I've read that it's on the lock module inside the driver's door. I haven't removed the panel to get to it yet.

so what is the ECU

I think the Electronic Control Unit is inside of the driver's door, and should have the code on it. A dealer can retrieve your code with the VIN, for a fee.

Thanks to all. Not located on door panel or inside trunk. Had dealer to reset it with new one. $40+ fee from manufacturer, they said. Works great now.
