I don't remember the specific process, but there are two versions of the opener. I don't recall what determined which one you got. Homelink is one. Can't remember the name of the other. You need to read the manual to determine which you have and procedure.This is a great thread and I'll bump it with a question.
I'm sure it's buried somewhere in the owner's manual, but how do I program the built in garage door opener?
