  • SureFlap DualScan Pet Door that controls cat access with microchip scanning from the inside and outside
  • Perfect for homes with both indoor-only and indoor-outdoor cats
  • Keeps out raccoons, neighborhood cats, and other unwanted critters
  • RFID collar keys available for unchipped cats

The SureFlap DualScan Microchip Cat Door controls which cats are able to enter and exit through the pet door. The majority of microchip pet doors only scan when a pet is trying to get back inside, but the SureFlap DualScan Cat Flaps ensure that indoor-only cats remain indoors while indoor-outdoor cats have the freedom to come and go as they please. It also protects against unwelcome raccoons, strays, and other critters from entering through the flap opening. This dual scan pet door is compatible with all common microchips in North America. RFID collar keys are also available for purchase in the case that your cat is not chipped.


  • Installs in all doors and walls.
  • For glass, metal doors, security doors, metal garage doors, or UPVC coated metal doors you will need to purchase a mounting adapter to ensure that the SureFlap DualScan cat door functions properly. For wall installations, you will need an adapter and the wall liners.
  • This 5 5/8” x 4 3/4” cat flap for doors is made of clear, rigid acrylic to ensure that raccoons and other critters can't penetrate the flap.
  • Easily programs up to 32 cats.
  • Incorporates a custom feature that delays the locking mechanism for 10 seconds, just in case you have a skittish cat that feels spooked because of the locking noise.
  • Features a safety mode to allow indoor cats who got out on accident to get back in.
  • Microchip technology ensures that any unwanted animals cannot access your home.
  • Operates on 4 AA batteries that usually last around 6 months.
  • When batteries are low, an indicator light flashes every 5 seconds. Replace the batteries when this light is flashing. When the batteries die, the door defaults to the locked position, which could leave pets stuck outside.
  • 4-way locking device (in/out only or completely locked/unlocked) included in the case that you want to disengage the electronic technology and use the cat door manually.


  • Raccoon and stray resistant.
  • Eliminates the need to manually lock/unlock the pet door.
  • RFID collar keys available to buy if your cats are not chipped.
  • Perfect for households with indoor-only and indoor-outdoor cats.
  • You'll no longer need to wake up in the night to let the cats in or out.

Installation Instructions

How to Install in a Door

How to Install in a Door Animation

Training Sessions 

Getting Started: Some pets will take longer than others to acclimate to their new door, so patience is key! Never push or shove your pet through the door (this will only develop negative feelings). Instead, follow these training tips + tricks to help introduce your pet to the door gradually.

Limit training sessions to no more than 10 minutes at a time. Two well spaced out sessions per day should be the maximum.

Hold the flap all the way open for your pet at first; then a little less each subsequent time so your pet learns to push through on their own. Stay consistent with verbal encouragement and treats for best results.


Teaching Your Cat to Use Their Door

Step One: Introduce your cat to the door by putting your hand through it so they know how it works. Have them inspect the new cat flap to get used to the look and smell (this is a great time to program your cat’s microchip!).  

Tip: You can wipe your cat’s face or body with a cloth and wipe the door with the same cloth to give it a more familiar scent. 

Step Two: Some cat doors make a slight clicking noise when opening and closing which can scare timid cats. Try manually opening and shutting the flap slowly to familiarize your cat with this noise. 

Step Three: Get your kitty’s favorite treats or toy ready! Start by using a treat to encourage your cat through while holding the flap open for them. Once they are comfortable, start lowering the flap on them as they walk through for their treat.

Tip: Be sure to train your cat using the actual door height - meaning raise the door enough so it resembles how high it will be once installed.

Tip: If you have a door with non-removable magnets, putting some painter’s tape over the magnets can help decrease the magnet attraction strength temporarily for training purposes.

Step Four: Always make sure to reward your cat with praise (and maybe another treat) when they pass through the door.  Remember: training can take a considerable amount of time. There is no standard practice as every cat is unique.


Quick Tips

- For especially timid cats, temporarily tape it up out of the way while they get used to the idea of walking through the tunnel.

- Clear flaps may confuse pets as they might think the flap is a window. Try putting a piece of masking tape on the clear flap to distinguish it from a window and reinforce to your pet its use as a door.

- Magnetic and weighted flaps have additional weight which may be difficult for your pet to push through. Fix this problem by gently pushing the door to assist your pet as they go through or removing the magnet until your pet gets used to the full weight of the door on their own.

- If you plan on installing more than one pet door, use the same flap if possible for consistency.

- Electronic flaps make a small clicking noise when the flap is activated that may frighten timid pets. The best way to remedy this problem is to positively reinforce this sound in your pet’s mind.

- Praise your pet when they come near the door and hear the activation noise.

- If this does not work, disable the electronics with “training mode” and have your pet use the door manually for a week or so while getting acquainted with the door.

- Consistency is key! Stay consistent both in your training methods and your choice of pet doors. If you have multiple pets the first to learn will often demonstrate  for the others!

- When your first lock the flap shut, introduce your pet slowly rather than letting them “learn the hard way” by running into it.


How To "Learn" your cat into your DualScan Cat Flap

What is a Microchip?


Does this cat flap work for all cats?

While this is model is a cat flap size, it is best to check your cat's height and width to make sure they will be able to go through this opening. Consider how high you are installing this item as well. You can cut a hole in a piece of cardboard to the flap size and see if they fit.

Is this raccoon-proof?

With the dualscan technology's ability to control access of animals from the inside and outside, this does result in it being highly raccoon resistant.

Can I get a larger size and control access both ways?

There is not a larger version that can control access from inside AND outside. The larger SureFlap Microchip cat door only controls entry from the outside.

Will this prevent my indoor cat from following the outdoor cat outside?

The Sureflap Dualscan Microchip cat flap will lock after a few seconds. A cat can tailgate another only if they are right behind, so it is possible depending on cat behavior.

Can I unlock this so my cat can go in and out without a chip or collar signal?

There is a safety learn mode that can enable this feature, where any animal can enter and exit.

Is this well insulated for extreme climates?

This Sureflap cat door comes with a few features helping insulate your home. There is weather stripping on the sides of the flap which helps seal your door against the outside environment. With its locking mechanism, it also keeps the flap from opening and closing.

Can I put this in a wall?

Yes! There are wall liners sold separately for installation. If your wall is especially thick, you may need a cat door tunnel extender in order for your cat flap to have the proper tunnel depth. In addition, we have mounting adapters for glass doors as well.

Can I put this in my french door?

Yes! You would need to get the mounting adaptor in addition to the door which allows you to install it through glass and other thin material. Unless you have experience, you would want to consult a glass company. This adaptor is sold separately on our website.

How many collar keys does this come with?

None, however you can purchase a set of two extra SureFlap RFID collar keys.

I need more than one door, do my cats need to wear multiple chips and/or collar keys?

No, with the dual scan microchip door you can simply program on-chip or key to all the doors you may have in your home.

Is the SureFlap 08SFDS raccoon resistant?

Yes, it is. You can set exit permission to control when specific pets exit the home. If you need a large pet door opening, the SureFlap Microchip Pet Door has a 7"w x 7"h opening is raccoon resistant too and can accommodate small dogs.
