298-11045 - PetSafe SmartKey One Size

Add an additional pet to your Electronic SmartDoor or replace your current SmartKey. Our innovative Smart Door recognizes the SmartKey worn on your pets collar and unlocks the pet door. After your pet has passed through and the SmartDoor no longer senses your pet's SmartKey, it automatically locks back into place. Each SmartDoor can program up to 5 SmartKeys.
