Best Suited For

Ideal for:

  • Smart Smartphone Control: Managing multi-pet schedules, monitoring access logs, and adjusting lock settings remotely from anywhere using the My PetSafe smartphone app.
  • Households with microchipped cats seeking keyless access (Medium size reads implanted FDX-B, FDX-A, and AVID microchips).
  • Multi-pet homes requiring selective entry programming for up to 5 individual RFID collar keys.
  • Standard door installations up to 2-1/4" thick needing dynamic weather sealing for draft protection.

Not ideal for:

  • Extra-large dog breeds or owners preferring a non-electronic door (consider the Endura Flap In-Door Pet Door for manual, high-performance weatherproofing in larger sizes).

Questions

Should I choose a single flap or a double flap?

A double flap traps a pocket of still air between the two panels, and that air gap is what does the insulating. If you have real winters, real summers, or a door that faces prevailing wind, the second flap is the difference you will actually feel.

A single flap is easier for a hesitant, small, elderly or recovering pet to push through, and it is the better choice in a mild climate or on an interior opening where insulation is not the point. If you are torn, consider which matters more day to day: the energy bill, or how confidently your pet uses the door.

What size hole do I need to cut?

Every pet door has a hole size that is smaller than the outside of its frame, and different again from the flap opening your pet walks through. The hole size is the one you mark on the door.

You will find it in the size guide on the product page, listed beside the flap and frame dimensions, and the installation instructions include a printable template you can tape in place before cutting. Mark from the template rather than from the frame itself. The frame overlaps the opening by design, so cutting to the frame leaves a hole that is too large to seal.

Will this fit the hole left by my old pet door?

Sometimes, but it is worth checking before you order rather than after. Pet door brands do not share a standard hole size, so a large from one manufacturer is rarely the same opening as a large from another, and a new door that is slightly smaller than the old hole cannot be made to cover it.

Measure the existing hole itself, height and width of the opening in the door or wall, not the frame around it. Compare that against the hole size in the size guide on the product page, which is listed separately from the flap size. If the new hole size is larger you can usually enlarge the opening. If it is smaller, look for a door with a wider frame that will cover the gap.

Product Details


The PetSafe SmartDoor Connected Pet Door provides complete control over your pet's access directly from your smartphone, keeping unwanted critters out while granting personalized entry for multiple pets. Featuring custom scheduling, microchip compatibility, and dynamic weather sealing, it ensures secure, energy-efficient independence for your cats and dogs.

Smart App Management & Scheduling
Using the My PetSafe app, you can remotely lock or unlock the flap, monitor access history with push notifications, and create tailored curfew schedules for each pet. This customizable system makes managing multi-pet households effortless and secure from anywhere in the world.

Microchip & Collar Key Access
The SmartDoor grants entry selectively to authorized pets. The Medium size allows cats to unlock the door using their implanted microchips (compatible with FDX-B/15 Digit, FDX-A/10 Digit, AVID H, and AVID Encrypted/9 or 15 Digit microchips). Both the Medium and Large models can also be programmed to recognize up to five separate PetSafe Collar Keys, ensuring wildlife and neighborhood strays stay safely outside.

Weatherproof Design & Installation
Equipped with a dynamic weather seal, the flap maintains tight insulation against drafts and temperature loss. While designed for standard doors up to 2-1/4" thick, the SmartDoor easily adapts for full walls, metal doors, or glass surfaces using dedicated tunnel extensions and installation adaptors. To bypass battery swaps, connect the unit to standard household power using the optional Electric Outlet Adaptor.

Technical Specifications & Features:

  • Wildlife Protection: Advanced locking mechanism safeguards your home against raccoons, stray cats, and other outdoor animals.
  • Multi-Pet Profiles: Easily program and monitor selective entry for up to 5 individual SmartKeys.
  • Collar Key Sizing: Key fobs vary by door size, with Small keys measuring 1"w x 1"h, Medium keys at 1.2"w x 1.2"h, and Large keys at 1.24"w x 1.6"h.
