My Old Sears Garage Door Opener: Anyone Can Open it now
I bought a townhouse with an older Craftsman Garage Door Opener. I bought a Universal Remote and programmed it to open and it did. Now several of my neighbors can open my garage door. I tried reprograming the original remote by moving the dip switches and it worked. The universal doesn't open it, but my neighbors still can.
The garage door opener works fine, so I don't think buying a new one is the solution, but I am at a loss at this point.
