A pet door offering ingress or egress through a structural member. A lock mechanism in the pet door allows the pet owner to restrict ingress and/or egress as desired. The pet door features a dual control system that simplifies the setting of the lock. Each control corresponds to movement of the flap in one direction. The dual control system is also designed to be easier to access than a conventional pet door lock mechanism and to be less susceptible to unintentional adjustment resulting from incidental contact with the controls.
