Add an additional pet to your Electronic SmartDoor™ or replace your current SmartKey™.  Our innovative Smart Door™ recognizes the SmartKey™ worn on your pet’s 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™.

The SmartKey™ is for use with the Small and Large Electronic SmartDoor™.
