Petsafe - Smartdoor™ Electronic Pet Door – Large - White

The SmartDoor ™ uses radio frequency technology to read the unique signal from the SmartKey ™ and this causes the lid to unlock, allowing your pets to walk in and out as they wish. When the SmartDoor ™ no longer detects your pet's SmartKey ™, the cover will close automatically. The SmartDoor ™ can detect up to five pre-programmed SmartKeys ™ and also works in two other modes: fully locked mode and unlocked mode.
