How do I program my SureFlap Microchip Cat Flap?
Programming is straightforward: insert batteries, wait 10 seconds, use Learn Mode. The manual says Learn Mode is used to program the cat’s microchip, and the chip only needs to be programmed once per cat because the number remains stored even after batteries are removed.
- Insert 4 AA alkaline batteries, leave tunnel empty for ~10 seconds
- Press and hold the Learn button until the indicator light flashes
- Place your cat near the door so the microchip is read
- Repeat for each cat – up to 32 microchips
What are people saying about the SureFlap microchip cat door?
Users widely appreciate the selective entry for their own cats. One owner reports: “The flap works great for keeping out neighbor cats, but the battery died after 8 months.” Another listing notes: “Works with all microchips, typically having 9, 10 or 15 digits.”
Some users mention shorter battery life than advertised, and installation can be challenging on glass doors or unusual frames.
The security upgrade works exactly as advertised, but owners should budget for premium alkaline batteries and a careful afternoon install.
Do microchip cat flaps actually work?
Microchip flaps only allow pets with programmed chips. An intruder cannot activate the microchip sensor, so the door remains closed to unprogrammed animals. However, the physical flap can be forced open if not locked – the microchip reader prevents entry, but it is not a solid security barrier.
The pattern: the electronics provide selective entry, but the plastic flap can still be pushed open by a determined animal or person.
How long does the SureFlap Microchip cat flap battery last?
Battery life is 6–12 months on four AA alkalines, depending on usage and battery quality. SureFlap Connect adds remote control via smartphone and smart home integration, but the flap works perfectly without the Connect hub.
Which microchip cat door is the best?
Compared to the PetSafe model, the SureFlap offers a longer battery life in some conditions and stores up to 32 microchips, while PetSafe stores up to 40. The choice depends on your needs.
| Battery life | 6–12 months (SureFlap) | Typically 6–9 months (PetSafe) |
| Max pets | 32 microchips | 40 microchips |
The implication: SureFlap is better if you have fewer cats and want a longer battery life, while PetSafe might suit households with more cats.
