PetSafe Electronic SmartDoor

Selective Access

Choose which animals you want in and out with this collar-activated dog door.
Best Collar-Activated

Find on Amazon

This collar-activated dog door is definitely a game-changer, especially for those who live in rural areas. It comes with a small, waterproof SmartKey that easily attaches to your dog’s collar. Once your pooch approaches the door, it will unlock automatically allowing them to enter, then it will lock again once the SmartKey is no longer detected. For added security, each SmartKey must be programmed individually to your SmartDoor, which means you can’t use it at any other SmartDoor. This system is perfect for ensuring that other animals and critters are kept outdoors — unless, of course, your dog oh-so-graciously brings you one as a gift.


  • A wall installation version is available with the purchase of a Wall Install Kit
  • Programmable for up to 5 SmartKeys


  • The lock makes a somewhat loud sound that could frighten some pets

Frequently Asked Questions

How do I know if my dog will even use a dog door?

Any dog can use a dog door with proper training and a little encouragement. Treats, positive reinforcement, and patience will help to get your buddy used to their new door. There are also plenty of online videos for more tips and techniques.

Does a dog door make it easier for burglars to break in?

Small to medium dog doors would be difficult for an adult to fit through, but the large and extra-large doors might be big enough. With that said, a burglar seeing a door for such a large dog may be too afraid of encountering it, so your huge pooch and their huge door may actually be deterrents. If you’re truly concerned with this issue then a collar-activated dog door might suit you best, or you might want to find a slide-in close panel made from steel.
