The Large Automatic Locking Pet Sensing Door. This is the patented pet door that automatically unlocks its flap only when a pet with a "smart key" approaches, giving your dog or cat unlimited freedom of passage while prohibiting unwanted animals from gaining entry. The unobtrusive smart key attaches to a pet's collar and transmits a coded signal that activates a spring release in the door, allowing your pet to push through the flap (its range can be adjusted from 6" to 6'). Approximately 15 seconds after your pet moves beyond range, the door automatically re-locks; it can also be left in unlocked or locked positions. It comes with one smart key and can be used with up to five pets (additional smart keys sold below). The rigid polycarbonate flap creates a secure, insulated seal and has
a frosted surface to hide dirt and scratches. The pet door's weatherproof ABS frame installs in standard doors from 1 1/2" to 2" thick. Batteries provide power for about six months; the door requires four D batteries, the smart key uses an included RFA-67 battery. Large. For pets up to 100 lbs. 27" H x 17 1/2" W x 3 1/2" L. (38 lbs.)
