I recently moved into a house with a Chamberlin garage door opener. The previous owners left me no manuals. I have 2 remotes with fresh batteries. Just 2 days ago the remotes stopped working. I can open the garage door using the normal wall button, but niether remote now works. The wall button contains a small green light that is quickly blinking. Have I accidentally stumbled upon a locking mechanism that locks out remote usage?
