Re: programing garage door opener ???
The hardware for these garage door openers vary from country to country and reflect the different cultures.
For instance in some countries you program the opener so that it rings your door bell in a certain manner and the wife of the house, whose always home, scurries out and after bowing to her master opens the garage door. It's much cheaper as it saves getting a motor and track etc and the women do not or dare not complain.
Honestly, would I lie to you?
