You can use a camera from a cell phone or camcorder to see the IR (infra-red) signal coming out of the remote. Just turn on your camera and point the remote at it and push the button. If the remote is putting out IR, you will see the little thing flash showing that a signal is coming out of the remote.
To open the remote, there has to be a sliding panel or screw or something. Some of these remotes will have a little slot in the bottom with a clip that holds a battery in, or some will have a screw that you need to remove to get the back off and gain access to the battery. Let me know what you find so we can figure this out for you.
