Product details

The SureFlap DualScan Microchip Cat Flap keeps unwanted animals out of your home and enables you to keep some of your cats indoors whilst letting your other cats come and go. The DualScan cat flap reads your cat’s microchip when they come into or go out of the house, giving flexibility to multi-cat households. When a registered cat approaches the DualScan cat flap from either direction, it reads their microchip and the door unlocks. It remains locked for any non-registered animals that try to gain entry or exit, enabling your cats to feel more relaxed in their own home.

For deep walls, a SureFlap Tunnel Extender can be used. One extender provides an extra 5cm of width onto the cat flap.

Key features 

  • Makes cats feel more comfortable in their own homes
  • Cats with specific needs, such as kittens or disabled cats, can be kept safely indoors
  • Ideal for multi-cat homes to keep certain cats in occasionally e.g. following a vet visit
  • Exit permissions can be changed at any time
  • Compatible with all common microchips and the Sure Petcare RFID collar tag (not included)
  • Safety learn mode ensures indoor-only cats can enter through the cat flap if they escape through an open window
  • Battery powered – requires 4 x AA batteries which last up to a year (not included)
  • Low battery indicator light gives you plenty of notice when the batteries need changing
  • Can be installed in doors, glass or walls
  • Four-way manual lock allows greater control of a registered cat’s entry or exit
  • Stores up to 32 pet identities

Please note: to install this product into glass or a wall, a SureFlap Mounting Adaptor is required. 

Size Guide


  • Flap opening size (the smallest area your cat will have to enter) – 142mm (W) x 120mm (H)
  • Door/wall mounting hole size – 165mm (W) x 171mm (H)
  • Glass mounting hole size (a circular hole is required) – The optimum hole size is 212mm in diameter, but it can be installed in holes up to 260mm in diameter
  • Exterior frame size – 210mm (W) x 210mm (H)

Additional Information


The presence of a metal plate in an installation location can influence the performance of the DualScan Microchip Cat Flap, reducing the range of the microchip reader. This includes the following:

  • Metal skin doors
  • Security doors
  • Metal garage doors
  • UPVC coated metal doors
  • Metal frames around a wall installation

For most situations you will not notice anything, as the read range will still be sufficient for the majority of microchips. However, if you experience intermittent operation or failure to open for your cat, first check for the presence of a metal plate in your installed location.
Note: UPVC coated metal doors often look the same as standard UPVC doors and you may need to look carefully where the panel has been cut. If a metal plate is confirmed, follow the instructions below for improved read range. 

If there is metal present, you will need to cut a larger hole in your door, leaving a gap of 2-3cm (1-1.2”) between the tunnel of the cat flap and the metal in your door. To begin with, trace around the outer edge of the back frame as a size guide. Now mark your cutting line 1cm (0.3”) inside the line you have traced around the back frame, leaving the screw holes in place. Cut this hole and reinstall the cat flap.

If you still experience intermittent operation you will need to increase the size of the hole again, in this case you will require the cat flap mounting adaptor.

Once you have the mounting adaptor, trace around the circumference of the mounting adaptor as a guide. Now mark a circle approximately 2cm inside the line from the mounting adaptor, again leaving the indentations for the screw holes. Cut this hole and then reinstall the cat flap again. This will extend the read range further and should resolve any issues with mounting in a metal door.

  • No good for clever cats!
    We have three cats, and lock them in at night. It took Dotty around a week to work out if it’s in the “come in” only mode, and she wants to get out, all she needs to do is put her head close to the door, till the lock clicks open, and then she can put her claw under it, pull it TOWARDS her, and sneak out under it! Now we have to monitor, which cats have come in, make sure none has gone out again, and then put the manual lock across. And it means one can't trust it to keep one cat in, while letting the others out. Either my cats are geniuses, or there is a fundamental problem!

  • Easy to fit and effective
    Bought and fitted around 3 weeks ago. Easy to fit and programme to the various pets in the household

  • Great for keeping cats safe
    This is perfect for keeping new cats safely indoors whilst still allowing others in and out. It's easy to use. One of my cats is scared of the noise the lock makes when it unlocks, but that's no reason to give this any less than 5 stars. He will get used to it eventually when he sees others go in and out unharmed I'm sure.

  • The best cat flap — ever
    This cat flap was easy to fit, well-made, and very easy to program. I had anticipated having to hold down buttons while dragging my reluctant moggy past the sensor but no, it's much easier than that. Press a button, and the next cat through is granted access. I was thrilled with that, and it works like a dream. My cat gets in and out with no problems, but Daisy — the neighbours cat that looks like a cow and eats like a pig and used to invite herself to dinner every night— can't get in any more. I really couldn't be happier with this cat flap. Would recommend it to anyone.

  • Still in a flap.
    A well made quality item and am very pleased with it. It works well and programming is a simple matter of pressing a button then getting the cat to go through. If only you could teach the cat that simply.
