Hi Ron & Laura! Welcome to IRV2! We're sure glad you found us!
On our Windsor the keyless entry program button was hanging down behind the radio and drawers in the center of the dash. It's a very small pushbutton and would be easy to miss in all the wires.
Be sure to visit us over in the Monaco Owners area of the forum. Lots of good info for a new Monaco owner over there!
Good luck, happy trails, and may God bless & keep you safe!
