they do not have the button. i have chevy sonic ones they are the same thing but no button. ours our two pieces with electrics inside them. i have a set now. they also share the same part number as the chevy volt. volt ones come black. i also found out that the SS comes with an option with NO chrome on the door handle. but obviously that is not a option when you order the car.
give me a few and i will post photos.
