PetSafe® Electronic SmartDoor™- Large

Type: Dog Doors

Vendor: PetSafe®



Our innovative Electronic SmartDoor™ gives your pet a key to the house so he can come and go as he pleases. 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.


Small children can pass through door.
