Two c-1c remotes on same genie door opener

I can program each remote but not both for the same door

Programming the second seems to cancel the first one out

Any help?

Actually we made a faq about this problem, please see below.


I purchased the C-IC as an replacement for my original genie, but I’m having problems programming

But the code for my old genie had numbers and I have no clue does this mean I need to change the code to my opener in the garage? How do I find the BBcodes to format

What’s your genie remote’s model number?

Or please send me your genie opener’s model number.
