SureFlap Microchip Pet Door Connect - My Top Pick
The SureFlap reads Bodhi's existing microchip - no collar key required - and unlocks the door only when he approaches. The companion app shows me every entry and exit timestamped, which has been weirdly addictive to scroll through. Setup took about 45 minutes including programming his chip, and the door has run on the same set of C batteries for nine months. The dual-flap design seals tightly enough that I don't feel a draft in winter.
Check price on Amazon →I installed five automatic pet doors across two homes to find out which ones keep raccoons out and let my dog roam freely.
My golden retriever Bodhi figured out how to nose open a manual pet door in under a week, which meant every neighborhood cat and one curious opossum followed him in. I installed my first automatic pet door three years ago, and I’ve cycled through five different models since. The good ones are life-changing; the bad ones are expensive trim around an open hole.
This guide reflects what I’ve learned from full installs in two homes – one with a hollow-core door and one through a brick exterior wall. The doors below are the ones I’d buy again.

SureFlap Microchip Pet Door Connect - My Top Pick
The SureFlap reads Bodhi's existing microchip - no collar key required - and unlocks the door only when he approaches. The companion app shows me every entry and exit timestamped, which has been weirdly addictive to scroll through. Setup took about 45 minutes including programming his chip, and the door has run on the same set of C batteries for nine months. The dual-flap design seals tightly enough that I don't feel a draft in winter.
PetSafe Electronic SmartDoor - Best for RFID Collars
PetSafe's SmartDoor uses a small RFID tag on your pet's collar to trigger the lock. I compared it with two dogs and a cat sharing the same opening, and the door responded to each one within about a foot of approach. The frame is sturdier than the SureFlap's, which I appreciate for medium and large dogs. It can store up to five pet profiles, useful if you have a busy household.
High Tech Pet Power Pet Door - Best for Large Dogs
The High Tech Pet Power Pet Door is the most secure door I've used. The motorized panel slides up rather than swinging, which means a determined raccoon can't pry it open. The unit plugs into mains power with a battery backup, and it works for dogs up to 100 pounds. Installation is more involved - I cut a precise rectangular opening - but the security and weather seal are top-tier.
Cat Mate Elite Super Selective Pet Door - Best for Cats
Cat Mate's Elite reads up to eight individual microchips, which is perfect for multi-cat homes. The flap is light enough that even my older cat doesn't hesitate pushing through. A built-in curfew lets me lock the door at sundown automatically, which has kept my cats safe from the coyotes that prowl my neighborhood. Battery life with four AA cells is around six months.
Endura Flap Automatic Pet Door - Best for Cold Climates
I installed an Endura in my Vermont rental and the insulation is genuinely impressive. Triple-seal magnets and a thermal-rated flap kept the door from leaking heat even at minus 10 degrees. The locking mechanism uses an RFID collar tag, and the deadbolt-style lock feels far more secure than a basic magnetic latch. The flap takes a little extra push to open, which is the trade-off for the tight seal.
FAQs
Yes - models like the SureFlap line read your pet's existing ISO 11784/11785 microchip with no extra collar tag needed. Other doors require an RFID collar key.
Most include dual flaps and magnetic seals that work well in moderate climates. For below-freezing or coastal salt air, look for triple-seal designs and an insulated frame.
