PetSafe Smart Door Electronic Pet Door - Large

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.
