  • To select the most appropriate dog flap for your dog’s size, weight and needs.
  • We recommend that customers use the flap sizes to cut a hole in a cardboard box to see if the cat/dog will fit through it ok.
  • It is vital that you are confident that your cat flap purchase will fit in the desired place in your home. For example – if it is a glass installation, is the glass wide enough?

Ask a Question

  • How do you program smart keys?

    To avoid interference, place all other keys in the freezer. Program one key at a time. Place the battery in the key. Use a coin to turn the battery clockwise, locking it into position. The key will only flash red when the battery is low. Press and hold the Learn button down. The green indicator ligh t will begin to flash. Release the button. Bring the key towards the green light. The light will stay solid for two seconds, then go out. The key is now programmed. The door may unlock once the key is programmed. Move at least 10 feet away from the door and wait until the flap locks. It may take up to 15 seconds for the door to lock once the key is out of range. Slowly walk the key towards the flap until the pet door unlocks and your hand can push the flap open. Repeat these steps to program each additional key.

  • When installed, does the door have to somehow be \'plugged in\'?

  • Do I need to purchase additional items to install or does the product come with everything?

  • Is it possible to make it lock when it detects the key, instead of unlocking?

    This door can be set up for unlocked mode which allows entry and exit for all pets, locked mode which restricts access for all pets, or automatic mode which allows entry and exit only for pets wearing SmartKeys. You will not be able to set it for entry only and the SmartKeys will not be compatible w ith other products like containment or bark collars.

  • How hard would it be for a human to push through this door in lock mode? Would other critters be able to crawl in, such as mice?

    If the door is in lock mode it will take extreme force to break though the SmartDoor. PetSafe doesn't offer a security panel with their pet doors. The only way another critter would be able to get through the door would be if they are following directly behind your pet.

  • Can this be used along with an inground fence?

    This can be used in addition to an inground fence system. It uses radio-frequency technology to read the unique signal of a SmartKey worn on your pet’s collar and trigger's the battery power-driven flap to unlock

Brilliant for my spaniel

I had a local handyman install into my stable door. It’s expensive but worth the money as it’s the only way that my dog can get in an out while I’m on a conference call.
