If you can locate the control module under the rear package tray it will have the code on a sticker attacked to it. If you can’t find the module then the dealership can get it from the main computer.

Either on trunk hinge, or in trunk. Pull off the driver's door panel, and it's on the module in the door. I couldn't find mine anywhere else. The dealer can do it from the VIN, for a fee.
