Don't be afraid to yank hard, it is the only way you will get it off. To remove the panel, first you have to remove the panel over the mirror adjuster.I found if you put down the window, you can grab hold of the edge, and pull. So the main purpose of todays activities was to see what was inside the door, and how hard it the project would be. I had heard that some of the Sparks might have had the actuators for the locks in all the doors except the drivers door. I want to be able to use the OnStar system to lock and unlock the door via the mobile app. I want to have a single switch in the vehicle to lock and unlock the doorĢ.

My end goal is to hook up the four cabin door locks to the rear hatch lock switch. I did the preliminary exploration of the door to see what was inside and see what was required to install a keyless entry system.
