PetSafe Never Rust Electronic Pet Door

Overview

Unlike a plain flap that any animal can push through, the PetSafe Never Rust Electronic Pet Door reads a collar key before it lets a pet pass. The frame carries an insulated flap and a lock closure, and the unit mounts through a door of the stated thickness. Only the pet wearing the key gets through, so strays and wildlife stay outside.

Households that want to control which animal comes and goes get the point of the collar key, since the flap stays locked for every pet without one. The single included unit and the one door thickness the frame accepts are what narrow the audience. A home with several pets, or a door that does not match the stated depth, will need another approach.

Who it's for

Owners of a single large dog who want the flap to open only for that animal will find the collar key does the work. Households with cats and dogs sharing the door, or anyone whose door is not the stated thickness, should look elsewhere. The single included unit also means a second pet needs its own setup.

Pros and cons

Performance notes

The collar key is the whole mechanism: the flap stays locked until the pet wearing the key comes near, so the door decides entry rather than the animal pushing through. Weather resistance comes from the insulated flap material, and the lock closure holds the panel shut between passes. How smoothly the flap swings over time depends on the frame staying aligned in the door.
