Howdy, Kale. Sounds like you have a problem as what you describe is not normal even if it is locked on or you push the button on the remote while plugging it in. When I plug mine in nothing changes on the camera as I believe it is a passive component and not recognized by the camera until you press the button at which time it behaves identically to the built-in shutter button.
