Electronic Dog Doors & Cat Doors | Microchip Activated, Automatic & Smart Pet Doors

Do you want the freedom of a pet door but you worry about neighborhood cats or other critters entering your home? Do you have a cat that you want to keep in while you let the dogs out? Would you just feel more secure without an unlocked dog door leading into your home? An electronic, magnetic, RFID chip, or even motorized dog doors or cat door may be for you.

The smaller doors operate by the pet pushing through the flap once activated, whereas some of the larger options (like the High Tech) are fully motorized and will raise or lower for the pet. The motorized option is recommended if you have a more timid or elderly pet who has trouble pushing through a pet flap. It also has its own self-locking cover built-in, meaning you don't have to keep track of a separate piece. There are no cat-specific motorized options, so keep in mind that the collar key or smart key might be a bit bulky for them to wear. All of the large electronic doors will be collar activated, as there are no microchip options for larger dogs.

Pay close attention to measuring for size. Microchip technology is not compatible with larger dogs due to its limited frequency range. When selecting an electronic pet door, you'll also want to consider the power source, spare collar keys, locking mechanisms, and opening methods. These all play a role in the success of your door. Take a look at our Ultimate Guide to Microchips and Pets to help guide your decision and find the best electronic dog door for you.

The Best Doors by Category

The Vet-Implanted ID Microchip-

The Pros for this type of system are plenty. Most importantly, there's no collar needed because the door uses the ID chip that your vet implanted under the skin. The absence of the need for a collar pet door would work for that has a number of very important advantages. Some cats won't tolerate them at all. There's always some danger of a cat accidentally getting his collar hung up on a branch or another object, which can have disastrous consequences. (Break-away collars avoid that danger, but if they break away you've lost both the collar and the collar key possibly trapping the pet outside). In addition, the implanted chip doesn't add to the clutter if you've already got ID tags (you DO have an ID Tag, Right?) or a hidden fencing system receiver on the collar.

On the other hand, there are a few disadvantages. The largest pet door flap available with this technology is only 7”w x 7”h, this is the SureFlap Microchip Pet Door, which would not be suitable for larger pets. And most only control who comes in not who goes out, the exception being the Dual Scan, with a very limiting flap dimension of 5-¾”w x 4-¾”h. These doors are compatible with almost every North American microchip, but it may be wise to check with your vet to be sure you've got one of the right ones and, make sure that the chip is still at the top of the neck where it belongs and hasn't migrated somewhere else. If the chip has migrated down the back, it won't be in the right spot to trigger the door consistently. You can also contact our customer service team with the number on your chip, and we can double-check the compatibility. Finally, installation in a metal door can be tricky because it will mess up the system's reading.

The Magnetic Collar Key-

There are two types: For the first, the magnet actually pulls a lever inside the cat door, which unlocks the door. In this case, the cat door doesn't require any power, and there is no electronic circuitry to corrode or fail. For the second type, the magnetic field of the magnet is sensed by the pet door, and it unlocks in response. These Electromagnetic doors require power, in the form of a battery. In both cases, the collar key requires no power, as it is just a magnet. Magnetic collar keys are less expensive to replace and are waterproof and weatherproof.

On the other hand, the magnets used to pull an inside lever are relatively strong and more likely to pick up debris like nails and bottle caps. Since they're stronger, they may exert more pull than is comfortable for a kitten, and at least one manufacturer recommends that they not be used until the cat is a little older. The positioning of the pet door is important as the magnetic collar key has to come extremely close or make contact with the bottom frame of the pet door. If mounted too high or too low, the key might not trigger the door as it never gets close enough. Some manufacturers recommend that installation in a ferrous metal door may require that a wooden collar be built to isolate the pet door from the door. An aluminum door would not present a problem. Finally, a magnet is a magnet; there is no way for the cat door to distinguish among your pets or between your cat and a neighbor's cat that happens to also wear a magnetic collar key.

The Ultra-Sonic Collar Key-

High-frequency sound (much higher than can be heard by your pet) is not affected by sunlight (as were the infra-red type) or by the material that the electronic door is installed in or by the use of any other electronic like hidden fencing. The sensitivity of the microphones can be adjusted to allow the user to control the distance at which the electronic pet door activates.

But, batteries are required so you'll need to check them occasionally. The units are susceptible to damage from water. Even though there is a waterproof version, you shouldn't use this for a pet that swims. Finally, a few (but not all) cat owners have felt that the unit was too large and uncomfortable for their pet.

The Radio-Frequency Chip-

The PetSafe Smart Door, a popular electronic dog door, uses a chip that emits a radio frequency signal. When the door reads that signal, it unlocks, and when it can no longer read the signal, it locks again. The collar key can be programmed to emit a unique signal, and the door can recognize up to five different keys.

Of course, these keys require battery power and, again, some have felt t too large for their cats.

RFID Chip Collar Keys-

RFID technology is the latest to make its appearance in the collar key world and appears to have some strong advantages: They require no batteries, they are very durable and are waterproof.

While some, like for the Cat Mate Elite series, are perfectly appropriate for cats, others are larger, and you may not find them suitable for use by your cat specifically. Additionally, they tend to be on the more expensive side.

Electronic Dog and Cat Doors FAQs

Which type of collar key pet door is the best?

This is a difficult question to answer because different people have different needs and may not agree on what is "good" and what is "bad." However, we'll take a stab at it. Remember that the features of the pet door you want may be just as important or more important than the characteristics of the type of collar key that is used for giving partial or full access through your doggie or cat door. That being said, here are our favorites for each category of collar tag key.

Some electronic pet doors control access from outside only, while others are controllable from both sides. What difference does this make?

In most cases, the one way, outside access control only works fine. Here are the situations in which 4-way access control from both directions can be an advantage:

You want to keep an inside pet (or child) from going outside in addition to preventing strays and other animals from coming inside.

You are concerned about raccoons coming in through the pet door. At least some raccoons have figured out that a one-way control electronic pet door can be broken into by hooking the flap with a claw and pulling the flap toward the outside. Then they can come through the opening. No one knows if every raccoon can do this, but they are very clever.

Some electric pet door models are motorized while others require the pet to push the flap after unlocking. What's the difference?

Motorized electronic pet doors always control from both directions: non-motorized versions may be either one-way or two-way control.

A timid, arthritic, or injured pet may find it easier to use a motorized version since he doesn't need to learn to push anything; the door simply opens in front of him. This is probably the most significant advantage of a motorized pet door.

We suspect that the motorized versions may be slightly less able to keep a second pet from following the first out. It's true that the time the flap remains open can be made short. But it's still open to all during that time. The must-push versions present a following pet with a flap swinging toward him as the leader clears the flap door. That would seem to be a more effective deterrent.

Manual flap systems may be used in a non-electronic mode; motorized pet doors cannot.

What are the different power requirements of electronic pet doors?

As we've seen above, some magnetic dog and cat doors require no power source at all; neither for the door nor for the collar key. For the remaining electronic pet doors, there are four possibilities:

Some are operated by batteries only

What is the best electronic door for wall installations?

That would depend on what you are needed out of the electronic doggie doors. Electronic large dog door models are pretty sparse, but the best one would be the High Tech Power Pet Doors. However, if you need the electronic wall pet door to keep something in while letting other pets out, then go with the PetSafe Electronic.

Some may be operated with AC power thus requiring a nearby wall outlet.

At least one, the High Tech Power Pet, can use AC Power with a battery backup in addition to the first two options.

With an electrician's help you might be able to hardwire the pet door.

What problems are there with electronic pet doors?

The first is reliability. With electronic doors, there are more issues that are likely to occur. If a manual pet door works for you and your pet, we would definitely recommend the manual door as a better option. An electronic door can run into issues like a dead battery since there's no battery level indicator; this problem could occur unexpectedly and would hinder your pet from entering/exiting. On the other hand, the only time a manual pet door would stop your pet from entering/exiting is if you personally put the locking cover on.

Cost. Electronic pet doors, particularly the motorized versions, tend to be more expensive than manual pet doors. Lost collars and keys can add up, too. Although there certainly are some high-performance manual pet doors that are quite expensive as well.

Rigid Flaps. All electronic pet doors incorporate rigid flaps. However, some people prefer a flexible flap for reasons of safety and a softer surface for the pet to push. In this regard, it should be noted that the motorized pet doors do not offer the pinching danger of a normal rigid flap.

Insulation and Energy Efficiency. Most of these direct approach electronic doors do not have magnets or even a weather stripping lining on their flaps, making them more likely to leak air and let in the cold. Most energy-efficient pet doors are not electronic.

What does it mean to "control both ways?"

The option to control both ways allows the door to control which animals can enter and exit. This simple directional sensing system can prevent animals such as raccoons from getting inside, as well as keep your pet or even child inside when necessary. Access from both directions can be an advantage if you want to keep an inside pet (or child) from going outside while also preventing outside animals from getting inside without a cat or dog's collar key.

Which doors control access both ways?

The SureFlap DualScan Door, PetSafe Smart Door, High Tech, and Cat Mate 305/306control access both ways.
