Using radio-frequency technology, the SmartDoor™ Electronic Pet Door reads a unique signal of the SmartKey™ Electronic Key and triggers the flap to unlock so your pets can come
and go as they please. When the SmartDoor™ Electronic Pet Door no longer detects your pet’s SmartKey™ Electronic Key, the flap automatically locks back into place. The SmartDoor™ Electronic Pet Door can detect up to five programmed SmartKey™ Electronic Keys and also operates in two other modes: fully locked mode and unlocked mode.

WARNING: Small children can pass through door.
