My remote has stopped working and I asume that the battery is low or dead. Are there photos anywhere that shows how to get the case apart to change the battery ?

 

In your Owners Manual on page 82.

If you don't have one,( same you the search in this forum ) , here is the URL :

Edit - I assumed you were talking about the factory RKE remote, please correct the thread if this is a different remote.
