Give your pet a "key" to the house, and keep unwanted ones out. Installs in standard house doors.

Grant him exclusive access to your home, locking out unwanted visitors. Using radio-frequency technology, PetSafe's award-winning Smart Door recognizes the SmartKey™ tag on your pet’s collar and unlocks the pet door. After your pet has passed through, it re-locks automatically. Additional keys available for multiple pets.

The SmartDoor can detect up to 5 programmed SmartKeys and also operates in 2 other modes: fully locked mode and unlocked mode. Locked mode does not allow entry or exit for any pet and unlocked mode allows entry and exit for all pets. The door reads the unique signal of the key on your pet's collar and triggers the flap to unlock. When the door no longer senses your pet's key, the flap automatically locks back into place. Each key is programmed to only let that pet use the door, so other pets or stray animals can’t use the pet door.

  • Give your cat access to the litter box or your bedroom while keeping the dog out
  • Keep your cat in and let your dog out
  • Let your pets out during the day and keep them in at night
  • Prevent strays or other animals from entering
