The SureFlap Microchip Pet Door is a reliable pet door for cats and small dogs designed to keep unwanted critters and neighboring cats out of your house. Engineered with RFID technology, this SureFlap pet door is equipped with the fastest chip reader for pet doors on the market that can sense your pet's microchip. The SureFlap Pet Door works with all identification microchips supplied by your vet and the SureFlap RFID collar tags provided upon purchase. If installing in a metal or glass door, purchasing the SureFlap mounting adapter is recommended to prevent the door material from interfering with the microchip sensor. If you'd like to install it in a wall, you can do so by purchasing the SureFlap door and wall mount bundle.

Raccoon Mode:

Custom Mode 5 is the raccoon mode, making this door a raccoon-resistant cat door. As soon as the sensors detect an animal's head in the tunnel of the pet door, it scans to read the microchip. If the animal is not one whose chip has been programmed to trigger the door, the two locks on the exterior of the door are activated for added security. At this point, the unit will keep scanning for a microchip, and the exterior locks will remain engaged until approximately 10 seconds after the intruder animal has moved away from the door. When the exterior locks are engaged it makes it impossible for the raccoon to open the door towards them in order to get in. The interior locks prevent the raccoon or other stray animals from pushing through the door into the house. The combination of the two sets of locks has proved virtually impenetrable to raccoons in product testing.

Installation Instructions

Installing the SureFlap Microchip Pet Door in a Door

Installing the SureFlap Door Through a Wall (tunnel kit sold separately)

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 Sureflap Microchip Cat 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.

An Interview with the Inventor of the SureFlap Microchip Pet Door Including Comparison with the Cat Flap Version

Getting Started


Is there a microchip activated dog door a little larger sized for taller dogs?

Unfortunately, there is no larger microchip dog door available in this brand or any other brand. We do have other electronic pet doors that are larger, however no dog door with chip compatibility features.

What is 'raccoon mode'?

Raccoon mode is an additional security method. When it is activated, sensors will detect an animal's head in the tunnel and scan to read for a chip. If the animal does not have a chip programmed to the door, two locks are activated. These exterior locks are engaged until 10 seconds after the intruder leaves. These locks prevent a raccoon from pushing through the door into the house. Or pulling the door backward to get in.

Will this door open from the inside as well for a pet wearing a chip or collar key?

No. The SureFlap Pet Door will only read the signal from one direction, the outside. Any pet can leave, but access is controlled in terms of who can enter. For two-way control, take a look at the SureFlap Dualscan, more akin to a SureFlap Microchip cat flap.

How quickly does the flap close after my cat goes through?

The flap on the Sureflap large microchip cat flap will close as soon as your pet's body is through the door. The flap will swing shut and lock via tabs, which takes a few seconds.

If my batteries die do I have to re-program the collar keys and microchips?

No, the chips and collar keys should still be programmed in the Sureflap memory.

If I buy more than one door, do my pets have to wear multiple collar keys or chips to use them all?

No, you can program one collar key or chip to multiple doors and your pet will still be able to use each door. Each door can program up to 32 different pets.

Is there a security cover for this door?

There is no security cover for this as the different entry modes prohibit unwanted intruders, locking the rigid flap. The tabs and weather stripping also keep the your home sealed from weather.

Can I lock this so my pets can't go outside even with a chip or collar key?

Yes, there are different modes you can customize to restrict access. There is also a curfew mode, preventing a cat or dog to exit or entering during a time you set.

How do I know if my cat has a microchip?

Your vet should be able to identify whether your cat has a chip embedded, as well as letting you know if that microchip works with this door.

Will this tell me if my cat is inside or outside?

No, there is not function to let you know whether your pet is inside or outside. If you needed that feature you would want to get the SureFlap Connect model with the additional Hub, both are available on

Why isn't there a large Sureflap microchip dog door?

Well with microchip dog doors the door itself would have to be much larger for bigger pets to get through. This means that the range for sensing the chip is increased and because of that can be too far away for it to trigger the pet door lock consistently. Right now, Sureflap is working on a microchip dog door, but it still has a ways to go.

Can this pet door be installed in a glass door?

More than likely, No. The glass in glass doors is tempered and will shatter if you attempt to cut it. You can have a local glass company cut a hole, to the pet door manufacturer's specification, in a non-tempered glass. Then have then tempure it for safety. You will need this mounting adapter to have the SureFlap Microchip mount correctly.

Is this SureFlap Dog Door the only chip dog door?

This SureFlap Dog Door is for small dogs only since the flap size is 7"w x 7"h. It is the only Microchip dog door on the market.
