I got two, but one broke down and I had to get a new one, same model and brand as the older one
Please clarify your question ! What do you mean by engine? The remote sends a signal to the logic board that syncs up with it, make shure they are the same frequency so if the logic board is 315 MHz the receiving board should be the same , don,t think because they look alike that they are , please check the data tag on the opener and on the garage door opener to make shure that the frequency is the same !
