About the SureFlap Microchip Pet Door

Make that microchip work for you (and your pet!)

We microchip our pets in case the worst happens and they get lost. But what if we could benefit from that insurance plan without losing anyone we love? The SureFlap Microchip Pet Door allows you to do that.

Make that microchip work for you (and your pet!)

We microchip our pets in case the worst happens and they get lost. But what if we could benefit from that insurance plan without losing anyone we love? The SureFlap Microchip Pet Door allows you to do that.

Once programmed, it recognizes your pet's microchip and lets her pass through. If she doesn't have a chip, you can use the included RFID collar tag. This allows her freedom to explore outside, but with some limits, set by you.

SureFlap Microchip Pet Door locking modes

Locking modes

Mode 1: Normal operation — Your programmed pet can enter or leave at will. The microchip reader is on the exterior of the door, so when no alternate lock mode is set, any critter (chipped or not) can exit your house, but only registered pets can enter through the door. This is called "selective entry."

Mode 2: In only — Your pet can enter the house, but she won't be able to leave again.

Mode 3: Out only — Your pet can exit the house, but she can't reenter. This is great if, like me, you need to lock your dogs out while you prepare their dinner bowls!

Mode 4: Fully locked — Your pet can't enter or exit the house.

Mode 5: Curfew — You set the door's lock and unlock times. Your pet can exit the home after the unlock time, but don't worry — she won't be locked out if she's out there after curfew! When the clock strikes your selected curfew time, the door switches to in-only mode so she can come back inside. At that point, the door will lock for the night and she will not be able to exit again.

These are the standard locking modes, but the SureFlap Microchip Pet Door also offers a variety of less common (but possibly still useful) custom modes. They are explained thoroughly in the manual so take a look there if you want more customization options.

More details on the SureFlap Microchip Pet Door

Mark G.

Product Research


Overview: The Sure Petcare SureFlap Microchip Pet Door (SUR101) is designed for cats and small dogs, and can be installed into a door, glass, or a wall. The door interacts with your pet's implanted microchip or the included RFID collar tag to automatically unlock the door, allowing entry. The SureFlap Microchip Pet Door comes with an RFID collar tag, and installation hardware.

Note: For a Wi-Fi enabled, app-controlled Microchip Pet Door, see the Sure Petcare Pet Door Connect and Hub (sold separately).

Microchip Pet Door: The Microchip Pet Door has a built-in microchip reader that recognizes your dog's or cat's implanted RFID microchip or collar tag and unlocks the door to allow your pet (and only your pet) to enter through the door. (It allows any animal to exit.) Each microchip and collar tag must be registered with the microchip reader so it can be recognized. The Pet Door is compatible with all microchips commonly used for pets, including those with 15-digit, 10-digit, and 9-digit models.

Note: Additional RFID collar tags are sold separately by the manufacturer. Up to 32 pets can be programmed into the pet door at the same time.

On Board Controls: The pet door has six buttons under a removable cover. The buttons include: Function, Locking Mode (see below), Time Set, Lock Time, Unlock Time, and Add a Pet. A 2-3/4" LCD screen on the top shows the current, lock, and unlock times, as well as the locking and unlocking mode directions, battery life, Wi-Fi connection, and Microchip reader condition.

Locking Modes: There are five locking modes:

  • Standard: Allows only authorized pets to enter and all pets to exit.
  • Keep Inside: Allows only authorized pets to enter and prevents all pets from exiting.
  • Keep Out: Allows all pets to exit, and once outside, they are prevented from re-entering.
  • Lock Both Ways: All pets are prevented from entering or exiting the house, keeping all pets in their current location.
  • Curfew Mode: Sets a lock and unlock time, giving your pet access to the outside for a set period of the day (i.e. unlock in the morning, and lock at night). During the Lock Time, the door is set to Keep Inside mode, allowing your pet to enter if outside, but prevent him from leaving.

Installation: The Microchip Pet Door can be installed in doors, walls, and through glass. If possible, the door should be installed so that the base of the tunnel is at the same height above the ground as your pet's stomach. Suggestions for each installation type include:

  • Doors: The Pet Door can be installed in all door types, including wooden, plastic, glass, and metal. Metal door construction may impede the performance of the microchip reader, including metal skin doors, security doors, metal garage doors, and UPVC coated metal doors. It should not be installed in a fire-rated door, as it will reduce the effectiveness of the fire door.
  • Glass: The Pet Door is ideal for mounting in single or double glazed windows. Cutting glass should be performed by a qualified glazier. A Pet Door Mounting Adapter, required for glass installations and sold separately from the manufacturer, allows mounting the door in circular holes between 11-9/16" and 12-5/8" in diameter.
  • Walls: For wall installations, Pet Door Tunnel Extenders will likely be needed (sold separately by the manufacturer). Each Tunnel Extender fits snugly onto the 2-3/4" long tunnel of the pet door, and adds 2" to the overall length of the tunnel. Before beginning installation, you should consult a qualified builder to discuss the best location for the door, and for determining the presence of electrical wires, water pipes, or gas lines.

Dimensions: The Microchip Pet Door is made for cats and small dogs. The door creates a tunnel through the door, glass, or wall for your pet to enter or exit through. The door has the following dimensions:

  • Flap Opening: 7.0" (W) x 6.69" (H)
  • Tunnel Depth: 2.75" to 3" (optional extenders available)
  • Door/Wall Cutout: 8.15" (W) x 9.21" (H)
  • Glass Mount Cutout: 11.81" to 12.625" (minimum/maximum)
  • Exterior Frame: 10.31" (W) x 11.06" (H)

Power: The SureFlap Microchip Pet Door is powered by four C-sized alkaline batteries (not included). High quality, brand name batteries are recommended. Fresh batteries last approximately 6 months.

My dog is 11.5 pounds small door looks to small. Does that seem to be right size.?
[ Benji  Mar 04, 2021 ]
1 answer
We have a Morkie that weighs about the same and a huge cat topping 20 pounds and both fit through this door so you should be okay. It's a great product, works flawlessly and the batteries last a very long time.
[ Guy  Mar 05, 2021 ]
could this be installed on a piece of plexiglass or does it need to be a thinker base?
[ Jennifer  Jan 26, 2021 ]
2 answers
You might be able to if it were thick enough, but I believe it was designed to go thru a door or wall ! I have mine on my front door and it works great!
[ PAUL  Jan 26, 2021 ]
I would think a thicker base. We have ours on a wall.
[ Lisa  Jan 26, 2021 ]
can you get it in brown?
[ dave  Jun 06, 2020 ]

My microchip door is white and I have no idea if it is available in brown. I would direct you to the manufacturer for that answer. Sorry I could not be of more help.

who installs these?

Google "Pet Door Installation" -I used a local handyman. He removed my door from the hinges, cut out the hole, installed the SureFlap door and put everything back together. He was gone in less than 45 minutes. $100 -Good Luck
[ Kohen  May 27, 2019 ]
My husband is a great handyman and was able to install it for me. The hardest part is cutting the hole in the door. Once that is done there were just a few screws that hold the whole system in place.
[ Kristin  May 27, 2019 ]
can the pet door be installed in a 4.5" wall?
[ Ron  Apr 19, 2019 ]
1 answer
The maximum length of the tunnel with the optional extender is only 3." You would have to fabricate some sort of extension to make that work. This is intended to be used in a door rather than a wall.
[ Cosmo  Apr 28, 2019 ]  Staff
I have three pets. Two of them are indoor and outdoor animals. The third one I do not want to have access to the outdoors. The description seems to imply that the door allows all pets to have access to go outside,but it was a little confusing. Can someone please tell me if this device will allow two of my pets free access but keep the third one inside? Thank you.

Hi unfortunately it does not distinguish between animals leaving the house.
[ Ariel  Apr 15, 2019 ]
Sorry my cat is still in the learning phase
[ Norma  Apr 12, 2019 ]
Yes it will. However, if you are trying to keep intruder animals, such as raccoons out, it is completely ineffectively.
[ Kristy  Apr 11, 2019 ]
If you don't program the indoor pet's microchip the door won't operate for that pet.
[ Kohen  Apr 09, 2019 ]
Pets wear a "key" on their collar that allows as much, or as little access as you want. The door can be locked; in only, out only, in or out, no access at all...and even set on a timer to lock. It's pretty handy. However, we have barn cats outside, and if they follow right behind our keyed pets, they've gotten in a couple of times when the door is unlocked.
[ Julie  Apr 09, 2019 ]
Do you make a door for large dog breeds?

We do have one for large dogs that's made by PetSafe. Here it is: My Bio:

Will the unit fit a 4x6 wall? Is it single flap, or double flap (for weather protection)?
[ Randy  May 29, 2018 ]
1 answer
4 foot by 6 foot? Yes. I never set mine up, i just got a piece out to see if my dogs could fit through and they couldn't, but i think it's single?? Not sure
