PetSafe Electronic SmartDoor - Collar Activated Dog and Cat Door - Small to Pets

The PetSafe SmartDoor allows you to control your pet’s access. When the SmartDoor is set to Automatic mode, only your pets wearing the SmartKey can pass through the SmartDoor. As your pet enters the range of the SmartDoor, the SmartDoor detects the SmartKey and unlocks automatically. The range is adjustable up to 3 feet. After your pet passes through the SmartDoor, the door will lock automatically helping to keep the house pets in and outdoor animals out.
