Your animal in, the neighbor’s cat out · review
A large electronic pet door that opens for a battery-powered collar key rather than a microchip, for dogs up to 100 pounds.
What we take from it It is on this shelf, and it reads no microchip at all. It opens for a battery-powered key on the collar — five at most — and the key is a $24.93 consumable with a three to six month battery. For a dog up to 100 lb, which is more than any microchip door here will take.
A large electronic pet door for dogs up to 100 lb, opening for a waterproof collar key rather than a microchip. Four D-cell batteries. $200.99.
Every other door on this shelf opens for the chip already implanted in the animal. This one opens for a key worn on the collar — PetSafe’s Electronic Pet Door Key, sold separately on the tags shelf here at $24.93, with an RFA-67 battery stated at three to six months.
That changes the economics. A microchip door is bought once; this is bought once and then fed a key battery two to four times a year, per animal, forever.
It also changes what happens when the collar comes off. A chip cannot be lost in a hedge.
Size. Up to 100 lb of dog, where the largest microchip door on this shelf — the SureFlap Pet Door — specifies shoulders no wider than 6½ inches and a waist under 20 inches, which is a large cat or a small terrier.
If the animal is a labrador, this is the only door in this group that will take it.
“Programmable for up to 5 Electronic Pet Door Keys”, with selective entry, exit and auto-locking. Five animals is fewer than SureFlap’s 32 or Cat Mate’s unstated multiple, but the exit control matches the DualScan: who goes out is as programmable as who comes in.
The biggest cells on this shelf — SureFlap uses C or AA and claims twelve months. This publishes no battery life at all, on a door that drives a larger flap against weather.
Interior and exterior doors as standard; walls need a separate Wall Install Kit, which the listing names and does not include.
Battery life, flap opening dimensions, cut-out size and weight. For a door whose whole argument is that it is large, the opening is the one measurement missing.

Because it does the same job — selective entry — by another means. The distinction matters commercially: a microchip is free and permanent, while this needs a $24.93 key per animal with a battery lasting three to six months. Over five years and two cats that is a running cost no microchip door has. What it buys is size: 100 lb of dog, against a SureFlap door specified for shoulders under 6½ inches.
The animal cannot get back in. That is the structural weakness of a key against a chip, and it is why the shelf treats them as different categories rather than equivalents. The PetSafe key is waterproof and hangs with the ID tag, but a collar in a hedge is a locked door.
Only with the Wall Install Kit, which is sold separately and named on the listing. As supplied it is for interior and exterior doors. By comparison the SureFlap doors on this shelf state door, window or wall fitting with accessories available, and the mounting adapter for glass is a separate purchase there too.
