Additional PetSafe SmartKeys for the pets in your home
Extra collar key compatible with the PetSafe SmartDoor. Our 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.
The PetSafe Electronic SmartDoor recognizes the collar "SmartKey" on your dog and unlocks to allow your dog access. The sensing range is adjustable up to 3 feet. After your pet passes through, the door will relock again automatically. Animals without the SmartKey are not able to enter.
An PetSafe Electronic SmartDoor Large or PetSafe Electronic SmartDoor Small gives you the control over the access your pets have to the outside. Set the SmartDoor to Automatic mode -- just your pets wearing the SmartKey on their collar may pass come and go. When your pet is within the owner-adjustable range of the SmartDoor, the SmartDoor then detects the SmartKey and unlocks automatically. You can adjust the range up to three (3) feet. When your pet has passed through the Smart Door, the door locks automatically. Without the SmartKey, no other animals can pass through. |
