Do you have an android smartphone? If so, most of them can sense Infrared Light
if you aim the remote at the camera, open the camera app, and press each button
on the remote verfifying you can see the infra red led of the remote blinking.
If you do, chances are the remote is functional. If not, the keypad could be worn out.
If each button works, you may need to read the instruction manual for your receiver to
set the remote address to agree with your receiver.
