?Dinnertime ??? Only thing that makes sense is a LOCAL transmitter that is blocking the G/D receiver ! Moving up the street also translates to, "wait a moment until QRM shuts down" and try again !
Most likely Transmitter would be a Microwave oven with a dirty Door Seal ?? leaking a microwave signal that would/could block the receiver in the Garage Door Opener.
Two weak batteries in BOTH remotes , not very likely, working better from up the street !!
