Okay the problem I am having is that I just bought another remote for my garage door. I have 1/2 HP powered Craftman Door Opener Model 41A4315-7D. It's the exact same remote like my other one with the same exact frequencies, I checked.

The problem is that people mention there is a green/orange button you have to press on the unit to get it to learning mode. I have looked, it's quite hard to get all the way in the back but I have tried, I can't seem to find this botton the on the front or back. Where can I find this button? Is there any other way to program this?

Thanks
