The Big Differences Between Microchip and Automatic Pet Doors

While features vary depending on brand and model, there are commonalities between all microchip and all automatic pet doors. Here we’ll discuss them both. 

Microchip Pet Doors

Microchip pet doors, as the name suggests, utilizes embedded microchip technology, allowing your pet to access the pet door. Some microchip pet doors require an embedded microchip in your pet, while others provide an RFID collar key. However, if you’re looking for an electronic pet door that allows your pets in and out without the need for a collar key, microchip doors are the way to go.

The advantages of microchip doors lies in the security it provides against strays, other pets, and critters like raccoons. They will open to your pet’s unique RFID tag, and only that tag, giving your pet access and keeping everything else out. 


Automatic Pet Doors

Automatic pet doors function in a similar way to microchip pet doors, but without the RFID technology. They often use magnets or other technology to open or unlock the pet door. This usually means the dogs and cats have to wear a collar key or some kind of special collar. 

Unlike the microchip pet doors, there are a wide variety of brands and models for automatic doors, from unlockable manual doors to fully automated pet doors like the High Tech Power Pet Door

How Do They Work?

Both microchip and automatic pet doors require power to use. They will be powered by a battery or an AC power cord plugged into the wall. In general, smaller doors will be battery operated and use a simple locking mechanism, while bigger doors will be plug-in powered and have more robust automatic functions. 

The various functions of their electronic features differ from brand to brand and model to model, but they almost always have self-locking defaults that only unlock when a pet with the correct microchip or collar key comes within range. This range is usually less than a foot and helps prevent multiple pets from accessing the door while it’s open.

I Have a Cat. What Door Should I Look For?

Cats have the flexibility of choosing between a microchip cat door and an automatic cat door. We recommend basing the decision on a couple of factors.

Firstly, consider how comfortable your cat is with a clunky collar. Most automatic pet doors require the use of a collar key. These can be anywhere from one gram and the size of a quarter to much, much larger. If your cat has trouble, we recommend a microchip door, as they require no extra collar keys. 

Tip: Add a small weight (like a 9-volt battery) to your cat’s collar to see how well they move around with it. 

Secondly, consider what size door your cat would be most comfortable with. While most cats can fit into small places, your cat may be reluctant to do so. Most microchip cat doors will be smaller (around 5 ½” x 5 ½”). 

I Have a Dog. What Door Should I Look For?

Unfortunately, the technology of microchip dog doors has not yet solved the problem of dogs’ microchips. The biggest issue they encounter is the location of the implanted chip, as it is further on the back, rather than on the shoulders, where a cat chip can be found. The pet doors cannot read the chip from that far away, and the door will remain locked. 

Note: A dog can still utilize a microchip pet door if they have on the correct RFID collar key.

Since most manufacturers cannot create a microchip dog door for dogs, we recommend dog owners look into automatic dog doors. They will come in larger sizes and not carry the extra price tag associated with microchip doors. An added bonus is that dogs do not mind wearing larger collars!
