Pet doors with locks open only when a collar-mounted device transmits the correct code to the latch's receiver, allowing owners to have multiple flaps that different pets can use, e.g. a small cat flap to the back yard and a large dog door accessing a . Either type can be used to selectively allow one pet outside access, while denying it to another (e.g., an ill animal that needs to stay indoors).
