I was tickled to see how easy it was to program my garage door to be opened directly from the Clarity. It took me all of 20 seconds to accomplish both doors opened from two different buttons from the Clarity. However, immediately after doing this I noticed that my little "Lift Master Garage Door Opener" stopped working. This is a wireless, keyless little box that I have mounted on the outside of the garage and is very useful for the gardener and other people who need to get into the garage from the outside. The buttons no longer work as they always did and the doors don't open. The Clarity now is the only remote control opener that is working. Is it possible that somehow the two can't co-exist? Do I need to re-program the Liftmaster or get something different?
