My Garage Door Won T Open When I Press The Button

The remote signal is blocked.
My garage door won t open when i press the button. I have 2 craftsman 1 2 hp door openers each car has a remote and i am trying to get my remote to open with the large button on the remote and my wife s door to open with the other button. My garage door won t open or close the motor runs and the shaft turns bur doesn t engage the chain. When i returned from work today i pushed the button on my remote garage door opener but the door didn t budge. Consequently the opener will not react to activation prompts if the settings are off and the garage door won t close.
It opens and closes manually terry on march 10 2017. If pressing the button on your garage door s remote control doesn t work check the batteries first. Even after putting new batteries in the remote the garage door still is not. Any ideas would be appreciated.

My garage door remote works great until glad comes on after the light times out it works again please advise me what to do thanks. If you press the button and the door fails to activate something might be blocking the signal.
