Please help! My automatic garage door's main board went out & when it was replaced, our ADT key fob doesn't work anymore to open & close the garage door. Anyone know how to program it so it will once again open the door? The problem I have is my system isn't monitored anymore so ADT won't help me without charging $100 to come out & do it. They won't talk me over the phone so unless I can get it programed again, I am out of luck using my new garage door opener. Thanks.
