Use 2 wireless remote garage door openers for the same door?
Your wording is a little rough but I think you're asking if you can use 2 different openers on the same door, and the answer is yes. In most cases, there will be a way to program the openers, but sometimes you have to program the receiver on the door. There are a set of small switches inside the control that you can set to what ever code your door is set for. Your best bet is to check the website for the door you're working on. Tech support there will have all the answers you need.
