Product details

Designed for large cats and small dogs, the SureFlap Microchip Pet Door uses your pet’s existing microchip like an electronic door key to keep unwanted animals out of your home. The unique number on your pet’s microchip is permanently stored in the memory of the pet door, even when the batteries are removed. When your pet approaches the pet door from the outside, it reads your pet’s microchip and the door unlocks. It remains locked for any other animals who try to gain entry. Featuring a curfew mode, the pet door can be set to automatically lock and unlock at specific times each day, which is ideal if you want to keep your pet in at night.

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.

  • Purrrfect
    Perfect as long as it lasts, that is. I had one that stopped working after a few years, and in view of the cost of replacement kept it as an ordinary flap that admits all comers. Then, after the stray who made free of the facilities and ingratiated himself with She Who Must Be Obeyed my eldest cat made himself a permanent member of the household, and another cat began the same caper, I decided that enough was enough and bought a replacement. That has done the trick. It is also invaluable in keeping in the cat with a dickey ticker who needs pills twice a day.

  • Potentially an excellent product
    we purchased this cat flat to keep out intruders which it does, but we also needed to keep a new kitten in the house whilst giving our other two cats freedom to come and go. The only product in this range offering this option was an exceptionally small cat flap which would be difficult for normal sized cats to use, let alone Maine Coons, so we have had to revert to our old, less high tech flap for now which can be manually set to stop the kitten going out until he is big enough to join the others in the garden. It is a good product but would be so much better if the the exit mode could be programmed by chip as well as entry. I don't understand the logic - if only cats with chips programmed into the system can enter, why should any cat, chipped or not, be able to exit? There isn't even a manual override where you can allow entry for all but no exit, which is what we've had to do with our old cat flap and manually monitor until we can let the kitten out.

  • Really good cat flap
    Cat has got used to using the cat flap really quickly. Great that it only lets our cat into the house, but we are really glad we went for the bigger size as I think he would have struggled to get through the smaller one even though he's not a fat cat. Overall really pleased.
