The two contenders
SureFlap Microchip Pet Door
SureFlap
The category reference for selective cat access: unlocks to your cat's implanted microchip or a supplied SureFlap RFID collar tag, registers multiple pets, and turns every unregistered animal away — nothing to wear, nothing for the cat to lose. Manual modes lock, open or hold selective entry from the door itself. No phone control on this model; curfews and entry logs live in the connected sibling.
Strengths
- Reads the implanted microchip — access control the cat cannot shed, lose or leave on the windowsill
- Programmeable curfew mode locks and unlocks the flap at set times without any hub or app
- Registers multiple household pets on one door while still refusing every unregistered animal
- The deepest owner base in the category: 4.4 stars across nearly seven thousand AU ratings, with tunnel and sealing accessories for other install types
Trade-offs
- Sized and tuned for cats — a real dog traffic issue is the wrong tool for this door
- Battery-powered locking mechanism means periodic battery maintenance on a device set into an external door
- No app, no entry log and no remote locking — that is the connected version, not this one
- Cuts into a standard wooden door with a template; glass and sliding-door installs need different hardware entirely
PetSafe Electronic SmartDoor
PetSafe
A powered, dog-sized selective door built around a collar key: the flap unlocks when a pet wearing its waterproof SmartKey approaches, with adjustable detection range and programmable selective entry, exit and auto-lock options for up to five keys. The right shape of answer for a dog — including an unmicrochipped one — that needs a flap big enough to genuinely use.
Strengths
- Flap sized for dog traffic rather than a cat squeeze, with a powered hold/release mechanism
- Adjustable detection range so the door opens as the dog approaches, not nose-to-flap
- Programmable entry, exit and auto-lock modes with up to five registered collar keys
- Works for dogs without implanted chips — the key is the credential, so no microchip is needed at all
Trade-offs
- The whole system depends on the dog wearing the fob — a lost or removed key means a locked-out dog
- Needs mains power with battery backup, so it is a wired install rather than a pure battery flap
- Authorises by tag, not chip, so it is only as secure as your collar discipline; a stray wearing a stolen fob walks in
- Older product generation with a middling 3.8-star AU pool whose complaints cluster around sensor and flap behaviour
The verdict: it depends
This matchup is usually decided by the animal before it is decided by the product. SureFlap is the stronger engineering: an implanted chip is a credential that never falls off, and the door's curfew and multi-pet registration give a cat household genuine control over who and when. PetSafe is the more honest fit for a dog: a flap a cat-sized mechanism would never serve, gated by a key you manage. Buy SureFlap for a microchipped cat. Buy PetSafe for a collared dog. The only true cross-species choice here is which failure you can live with — a dead battery on an external door, or a lost fob on a wet Tuesday.
Choose SureFlap Microchip Pet Door if
- The pet in question is a microchipped cat, and strays, possums or wildlife getting in is the actual problem
- You want a credential the animal cannot lose — nothing on a collar to shed, swap or leave in the garden
- Curfew control matters to you: timed lock and unlock from the door itself, no hub, no subscription, no firmware
- You are fitting into a standard wooden door and want the deepest installed base and accessory range behind the choice
Choose PetSafe Electronic SmartDoor if
- The pet is a dog — this is the larger powered flap, and cat-sized selective doors simply do not serve dog traffic
- Your dog has no implanted microchip, or you prefer enrolling and revoking access by swapping a fob
- You want adjustable approach range so the door unlocks as the dog arrives rather than on contact
- You can maintain collar discipline — the fob stays on, and you accept that it is the system's single point of failure
List prices drift; position does not: SureFlap asks flagship money for its chip-reading mechanism, while the PetSafe powered flap typically lands mid-tier once you price the required collar keys. Factor installation honestly — a glazier or carpenter entry costs the same whichever door you choose.
Two philosophies of who gets through the flap
Selective doors all promise the same thing — only my pet — and the honest difference is what the promise is built on. SureFlap reads the ISO microchip fused under your cat's skin during registration: the credential predates the product, cannot be removed by the animal, and cannot be borrowed by the neighbour's tomcat. Every unregistered nose is turned away, which in Australian suburbia is the entire point — stray cats raiding food, possums walking in at midnight, and the wildlife that turns an unselective flap into an open invitation.
PetSafe's SmartDoor inverts the model: the door is dumb until the key is near. A waterproof RFID fob on the collar tells a powered mechanism to release the flap, at a distance you set, and up to five keys can be enrolled. That is genuinely better for a dog — no chip needed, a second's work to revoke a key, and a flap big enough for a real animal — but it makes collar discipline the security policy. A fob left on a bench is an invitation; a fob shed in the bush is a dog sitting outside in the rain.
So the first question is not which door is cleverer — it is which credential your household can guarantee for ten years. A cat cannot remove a chip and will not lose one. A dog removes collars with alarming creativity. If you cannot answer 'the fob stays on' honestly, the mechanism's size advantage stops mattering. The full field of options, from simple flaps to connected doors, is in our electronic pet doors guide.
Control features: curfews, locks and the missing app
SureFlap's quiet strength is time control without connectivity. Curfew mode programs the door to lock and unlock at specified hours from the unit itself — the cat-out-by-day, in-overnight pattern that protects nocturnal wildlife and keeps a cat off the road at dusk, with no hub, no firmware and no account to outlive the product. Manual modes on the frame give instant open, closed or selective states when plans change. The phone-control version of this door exists — it is the Connect sibling, hub and app attached — but this model deliberately stops short.
PetSafe programs differently: selective entry, exit and auto-lock modes shape how registered keys may pass, and auto-lock can secure the flap after use or on schedule-like conditions you set at the unit. What it does not offer is a true clock curfew — the door governs who, more than when — and neither product reports anything to your phone at this tier. For an owner whose real requirement is knowing what time the cat came home, both lose to the connected category.
The asymmetry that matters is directionality. SureFlap's curfew is designed for the cat-exclusion problem Australia actually has: keeping wildlife and raiders out at night while your own cat still has morning access. PetSafe's mode set is designed for traffic management in a dog household — let the puppy out, lock the flap during mowing, keep entry one-way during training. Same word 'programmable', completely different owner lives.
Power, install and the failure modes you live with
Power philosophy splits the two doors cleanly. SureFlap runs its locking mechanism on batteries — no wiring, no electrician, and the maintenance is a periodic battery change on a device set into an external door, which the format has long made simple and the rating base has long complained about in equal measure. PetSafe is a mains-powered flap with battery backup: a wired install that never nags you about cells, at the cost of needing power at the doorway and a more involved fitting than a cut-and-drop cat flap.
Both are wooden-door citizens. The SureFlap cuts to a template into a standard door, with tunnel and weather-sealing accessories for other builds; glass installs, and the entirely different sliding-glass-panel world, are not this product's territory at all. The PetSafe's size and wiring similarly assume a real door panel a carpenter can cut and power can reach. Rental households should price reinstatement into either decision honestly.
Failure modes decide long-term satisfaction more than features do. SureFlap's pool — 4.4 stars across 6,841 AU ratings — is the most-tried path in the category: predictable, well-documented, with a decade of troubleshooting knowledge behind any oddity. PetSafe's 3.8 across 4,218 is a useful, older product whose recurring complaints concentrate on sensor behaviour and flap mechanism wear. Neither is fragile; one is the beaten track and the other asks you to keep the fob story straight.

Frequently asked questions
Can the SureFlap door let my dog out as well as the cat?
Generally no, and this is the trap in the matchup. SureFlap is a cat-scale aperture: the flap is sized for a cat to squeeze through, which is exactly how it seals and how the chip reader works at close range. A dog that needs independent access needs a dog-sized flap — the PetSafe, a plain large flap, or two doors in two places. Choosing by the smaller animal is normal; assuming the bigger one will share the hole is the mistake.
Does the PetSafe SmartDoor keep out the neighbour's cat?
It keeps out anything not wearing a registered key, which technically answers the question, but the mechanism is aimed at dog households: the fob, the powered flap and the detection range are tuned for one animal you control, not for policing a stream of cats. For a genuine stray-and-wildlife exclusion problem on a cat, the chip-reading SureFlap is built for exactly that job and has nearly seven thousand AU ratings of experience behind it.
What happens when the power or batteries fail?
SureFlap runs on batteries and its manual frame modes let you hold the door open or closed through a flat-cell moment, so a dead set is an inconvenience you fix in minutes. The PetSafe is mains powered with battery backup, so a household power outage can mean a locked flap unless the backup is actually installed and current. Both are honest designs; just know that one degrades to a manual door and the other degrades to a dead mechanism.
Should I buy the app-connected SureFlap instead of either of these?
Buy it only if you will use the features it adds: remote locking from a phone, adaptive curfews and an entry log — all of which need the hub, your home network and an app account that must keep being supported. The non-connected SureFlap here gives you chip selectivity and on-door curfew without any of that upkeep. In a stable household, the simpler model is usually the wiser long-term purchase; the connected one pays off for owners who genuinely manage the flap from work or travel.
Can I install either door in a sliding glass door?
No — both of these cut into a solid door panel, which is precisely the opening most Australian patio doors cannot offer. Sliding glass gets its own hardware class: a clip-in panel that drops into the door track and lifts back out, though that category is mostly built around plain flaps rather than chip-selective electronics. We compare that distinct product family in our sliding glass door pet doors guide, and if selective entry is non-negotiable there, the honest answer today is a solid-door install.
