The remote systems on these 2012 rigs was made by GAMA Electronics. The program button referred to in the link below is on the receiver mounted on the ceiling of your front compartment. I never had to do this as we threw the remote in a drawer because it wasn't worth the hassle using it, and only found it again last year while searching for something else.
