When I'm in my house and the push-button on the remote is accidentally pushed, the garage door 200 feet away opens. Is there a way to reduce the distance?

Does your opener have a small wire hanging off of it? It's the antenna and would be some four to six inches long. It can be coiled or folded up as another poster suggested to make the antenna shorter thus reducing the range. ヽ(ヅ)ノ
