Give your pet a key to the house! With the PetSafe Large Electronic Pet Door you can let your pet come and go but still lock out unwanted visitors.
Using radio-frequency technology, the SmartDoor reads the unique signal of a SmartKey worn on your pet's collar and triggers the battery power-driven flap to unlock. When the SmartDoor no longer senses your pet's SmartKey, the flap automatically locks back into place. Animals without the SmartKey are not able to enter. You may have a total of 5 SmartKeys in use at one time.

I installed the large size door for my 130lb. black lab and the only thing I regret is not installing it sooner! Provides both my dogs with plenty of freedom to come and go as they please while I get ready for work in the morning or away at work during the day. The door sensor fob the dog wears is small and unobtrusive and the activation range is adjustable. I also like the feature that enables you to swith the door from "automatic" to "secure" at night although we leave it on "automatic" most of the time since it accomplishes the same thing.
