You'll need to begin by opening the doors up. There are 2 screws holding each door panel on. (9/32 socket will remove them)
The first screw is located under the "control panel" (the part with your window controls/lock controls), you remove this part by lifting the smallest end straight up. once the clip releases, pull up and out to remove the other side.
The red reflector can be removed with a flat head screw driver.
