For buyers comparing smart dog doors with microchip access, the first distinction is easy to miss: these three picks do not all identify pets the same way. My best overall choice is the PetSafe SmartDoor Connected Pet Door, which supports compatible cat microchips alongside its included collar key. The High Tech Pet Power Pet Smart Roll-Up is my pick for adjustable sensing and a draft-resistant roll-up panel, while the large refurbished High Tech Pet Power Pet WiFi Door suits households that prioritize app schedules and remote locking.

The tradeoff is between microchip compatibility, collar-based detection, installation limits, and the degree of remote control. PetSafe offers microchip access but has a 2.4 GHz Wi-Fi requirement and a relatively thin door limit. Both High Tech Pet models rely on a genuine MS-5 ultrasonic collar transmitter, not a pet’s implanted microchip. I rank them by how closely they fit this roundup’s access promise, then by practical control and installation details.
Key Takeaways
- PetSafe is the only listed model that supports compatible implanted cat microchips; the two High Tech Pet doors require a genuine MS-5 ultrasonic collar transmitter.
- The medium High Tech Pet roll-up model has the widest stated sensing adjustment, from a few inches to 20 feet, plus a panel designed to seal against drafts and pests.
- The large High Tech Pet model adds app schedules, remote locking, and activity notifications, but its refurbished condition and 2-inch door-thickness limit matter.
- PetSafe supports a maximum 1.5-inch installation thickness and requires 2.4 GHz-capable Wi-Fi; its wall adapter is sold separately.
- Choose by identification method first, then confirm your dog’s size, the installation location, power setup, and desired app controls.

More Details on Our Top Picks
PetSafe SmartDoor Connected Pet Door, Medium
I rank the PetSafe SmartDoor Connected Pet Door first because it is the only option here that explicitly supports compatible implanted cat microchips. That makes it the closest match for households that want identification tied to the pet rather than a dedicated High Tech Pet transmitter. It also includes a collar key, so the access system is not limited to microchip recognition alone. Buyers should check chip compatibility before purchasing; the stated support is for compatible cat microchips, not every chip format by default.
Its app adds useful control: owners can manage access, set schedules, receive activity and status notifications, and remotely lock or unlock the flap. Compared with the High Tech Pet roll-up model, PetSafe makes the clearest microchip-access case, while the roll-up door emphasizes adjustable approach sensing and a panel designed to seal out drafts, dust, and pests. Compared with the large refurbished High Tech Pet model, PetSafe has a much lower stated maximum weight capacity, so the large dog option may be a better fit for bigger pets.
The main constraint is installation. The PetSafe fits doors up to 1.5 inches thick, less than either High Tech Pet model’s stated limit, and it needs high-speed Wi-Fi with 2.4 GHz capability for connected functions. The wall adapter is sold separately, and extra Pet Door Keys are also separate purchases. Its weather-sealed flap and multi-point lock offer practical closure features, but this is not the pick for someone seeking the roll-up panel design or a door-mounted unit built around long-range collar sensing.
Pros:- Supports compatible cat microchips as well as the included Pet Door Key
- App-based schedules, remote locking, and activity and status notifications
- Weather-sealed flap with a multi-point locking mechanism
- Can run on batteries or an optional wall adapter
Cons:- Requires high-speed Wi-Fi with 2.4 GHz capability for connected features
- Maximum compatible door thickness is 1.5 inches
- Wall adapter and additional Pet Door Keys are sold separately
Best for: Households that want app-managed access and compatible implanted-chip recognition for a medium dog, and whose installation supports the 1.5-inch thickness limit.
Not ideal for: Owners of large dogs, buyers without 2.4 GHz-capable Wi-Fi, or anyone needing a door thicker than 1.5 inches or a roll-up panel.
- Size:Medium
- Access methods:Included Pet Door Key or compatible cat microchip
- Maximum door thickness:1.5 inches
- Maximum weight capacity:200 pounds
- Connectivity:High-speed Wi-Fi with 2.4 GHz capability
- Power:Batteries or wall adapter, sold separately
- Closure:Weather-sealed flap with multi-point lock
Our verdict“For microchip-first buyers with a medium dog and a compatible installation, PetSafe is the clearest match, provided its Wi-Fi and accessory requirements work for the household.”
High Tech Pet Power Pet Smart Roll-Up Automatic Dog Door, WiFi, Medium
This medium High Tech Pet Power Pet Smart Roll-Up stands out for how it detects an approaching dog and for its roll-up closure. Rather than asking a pet to nose-push a flap, it uses a genuine MS-5 ultrasonic collar transmitter to trigger opening. Its adjustable sensing distance runs from a few inches to 20 feet, giving owners room to tune how early it responds. A household with a busy yard may value the ability to shorten the range; a more open approach may suit a longer setting.
Against the PetSafe, the distinction is identification: this High Tech Pet door uses a dedicated collar transmitter, while PetSafe is the only option in this lineup that also names compatible implanted microchips as an access method. The roll-up model counters with four modes—Enter Only, Exit Only, Full Access, and Locked—and a panel intended to help seal against drafts, dust, pests, and unwanted entry. Safe-return and obstruction-detection features add useful safeguards, though they do not replace checking the opening and the pet’s fit.
Optional app and smart-home control, including Alexa, Google Home, and Siri compatibility, add flexibility, but Wi-Fi app control is optional rather than the core identification method. That makes this less appealing for shoppers who specifically want microchip-based access or who do not want a dog to wear the required transmitter. Its stated maximum compatible thickness is 6 inches, more forgiving than PetSafe’s 1.5-inch limit and the large refurbished unit’s 2-inch limit. Even so, buyers need to confirm the selected location, medium sizing, and transmitter requirements before deciding.
Pros:- Adjustable activation sensing from a few inches to 20 feet
- Four modes: Enter Only, Exit Only, Full Access, and Locked
- Roll-up panel is designed to resist drafts, dust, pests, and unwanted entry
- Safe-return and obstruction-detection features, with optional app and smart-home control
Cons:- Requires a genuine High Tech Pet MS-5 ultrasonic collar transmitter
- Wi-Fi app control is optional
- Medium sizing may not suit larger dogs
Best for: Owners of medium dogs who want adjustable collar-based approach sensing, multiple access modes, and a roll-up panel with a broad stated installation-thickness limit.
Not ideal for: Buyers who require implanted-microchip recognition, do not want their dog to wear an MS-5 transmitter, or expect Wi-Fi app control to be included as a standard feature.
- Size:Medium
- Mounting:Door mount
- Maximum compatible thickness:6 inches
- Access modes:Enter Only, Exit Only, Full Access, Locked
- Activation range:A few inches to 20 feet
- Transmitter:Genuine High Tech Pet MS-5 ultrasonic collar transmitter
- Smart-home compatibility:Alexa, Google Home, Siri
- Material:ABS plastic
Our verdict“Choose this model over PetSafe when adjustable ultrasonic sensing and its roll-up closure matter more than implanted-microchip recognition.”
High Tech Pet Power Pet Smart Automatic WiFi Dog Door, Large, Door Mount, Refurbished
The large refurbished High Tech Pet Power Pet WiFi Dog Door is the lineup’s size-focused pick, with a stated maximum weight capacity of 100 pounds and app control for schedules, remote locking, and activity notifications. Its directional sensing is intended to reduce false openings, while the fast, quiet panel has an automatic safety retract system. For a household managing a large dog’s access at particular times, those app tools are more central here than on the roll-up model, whose Wi-Fi app control is optional.
It still does not use an implanted microchip for identification. Like the other High Tech Pet door, it requires a genuine MS-5 ultrasonic collar transmitter. PetSafe is the better match for microchip-first households; this model is the more relevant alternative when a large opening and scheduled remote control take priority. The one-year warranty is a useful stated safeguard, but refurbished condition is a real distinction from the other listed options and may not suit buyers who prefer a new unit.
Fit can also rule it out. Its maximum compatible door thickness is 2 inches, which is narrower than the medium roll-up model’s 6-inch limit and just above PetSafe’s 1.5-inch limit. Check the actual door thickness before selecting it, especially if installing in an unusually thick entry. Its remote features depend on app connectivity, and the collar transmitter remains necessary for the dog to activate the door. Compared with the roll-up unit, it gives more explicit scheduling and notification detail, but offers less flexibility on stated installation thickness.
Pros:- Large size with a stated maximum weight capacity of 100 pounds
- Wi-Fi app supports remote locking, schedules, and activity notifications
- Directional sensing is designed to reduce false openings
- Fast, quiet panel with automatic safety retract and a one-year warranty
Cons:- Requires a genuine High Tech Pet MS-5 ultrasonic collar transmitter
- Maximum compatible door thickness is 2 inches
- Factory-refurbished condition may not fit every buyer’s preference
Best for: Owners of large dogs who want app schedules, remote locking, and activity notifications, and who accept a refurbished product and collar-transmitter access.
Not ideal for: Microchip-first buyers, owners with doors thicker than 2 inches, or shoppers who do not want a refurbished unit or a dedicated transmitter.
- Condition:Factory refurbished
- Size:Large
- Maximum weight capacity:100 pounds
- Maximum compatible thickness:2 inches
- Access:Genuine High Tech Pet MS-5 ultrasonic collar transmitter
- Control:Wi-Fi app and local control panel
- Closure:Deadbolt
- Warranty:1 year
Our verdict“For a large dog and a household that values scheduled app control, this is the strongest fit here, but it is not a microchip-activated door and its installation limit is restrictive.”
How We Picked
I compared these three doors against the specific promise of smart access for dogs, rather than treating every electronic flap as a microchip door. That distinction changes the ranking: PetSafe has the clearest fit for buyers seeking implanted-chip recognition, while both High Tech Pet models identify the dog through a dedicated ultrasonic collar transmitter. I spell out that difference because a dog without the required collar key or transmitter may not be able to use the door as intended.
Next, I weighed day-to-day control and safety features. App scheduling, remote locking, notifications, sensing adjustments, obstruction response, and the locking or closure design can affect how much control an owner has over unsupervised access. I also compared the stated installation limits, size, and power-related requirements. A feature is only useful if the door fits the opening and the household can support its connectivity and accessory needs.
Finally, I considered the tradeoffs that separate these models. The roll-up unit earns attention for adjustable sensing and a sealed panel; the large refurbished unit offers a stronger app-control emphasis but brings condition and fit questions; PetSafe ranks first for the roundup’s microchip-access intent, despite its narrower Wi-Fi and thickness requirements. The supplied specifications do not establish universal compatibility with every implanted chip, door material, or dog, so I treat those details as items buyers should verify before choosing.

Factors to Consider When Choosing Smart Dog Doors With Microchip Access
I would choose the access method before comparing app features. The word “smart” can describe schedules and phone control, but it does not mean every door reads an implanted microchip. These options split into one microchip-capable model and two dedicated collar-transmitter models.Check what identifies your dog
The PetSafe SmartDoor supports compatible cat microchips and an included collar key. The two High Tech Pet doors use a genuine MS-5 ultrasonic collar transmitter. Those systems are not interchangeable, and app control does not change how the dog triggers the High Tech Pet doors. If you want to avoid adding a transmitter to your dog’s collar, PetSafe is the clear starting point—but verify the implanted chip’s compatibility with the door before buying.
Match the door to your dog and opening
PetSafe and the roll-up High Tech Pet model are listed as medium; the refurbished High Tech Pet model is large and has a stated 100-pound maximum weight capacity. Do not use weight alone to decide: check the manufacturer’s opening dimensions and compare them with your dog’s shoulder width and height. Then measure the installation location. The stated thickness limits are 1.5 inches for PetSafe, 2 inches for the large refurbished model, and 6 inches for the roll-up model. A mismatch can make an otherwise suitable access system unusable.
Separate phone controls from pet access
App features answer a different question from pet identification. PetSafe lists schedules, notifications, and remote locking; the large refurbished High Tech Pet model adds schedules, remote locking, and activity notifications; the roll-up model offers optional app and smart-home controls. If you mainly need to stop access at night or set routines, compare the exact controls you plan to use. For the High Tech Pet doors, the dog still needs the required transmitter even when phone functions are available.
Think about closure and safety
The roll-up model’s panel is designed to help block drafts, dust, pests, and unwanted entry, and it includes obstruction detection and safe-return features. PetSafe uses a weather-sealed flap with a multi-point lock. The refurbished High Tech Pet model has a deadbolt closure and an automatic safety retract system. Those are different approaches, not a single measure of security. Match the closure style to your weather exposure and household concerns, and review installation guidance rather than assuming any electronic door will seal like a full-size exterior door.
Account for network, power, and extras
PetSafe requires high-speed Wi-Fi with 2.4 GHz capability for connected operation. Its wall adapter is sold separately, and additional Pet Door Keys are separate purchases. The roll-up model’s app control is optional, so buyers should confirm which package and connectivity functions they need. The large refurbished High Tech Pet model lists Wi-Fi app and local panel control, plus a one-year warranty. Before ordering, verify what is included, how the unit is powered, and whether the household’s network and installation plan support the features being counted on.
Decide whether refurbished condition fits
The large High Tech Pet model is explicitly factory refurbished, unlike the other two product titles. Its size and app functions may make it the right match for a large dog, but a refurbished unit is not the same buying proposition as a new one. Review the seller’s condition details, warranty terms, and included components. If condition is a deciding factor, the medium roll-up High Tech Pet door or PetSafe model may be a better direction, depending on whether collar sensing or microchip access matters more.
Frequently Asked Questions
Which of these dog doors reads an implanted microchip?
The PetSafe SmartDoor Connected Pet Door is the only option in this comparison that lists compatible cat microchips as an access method. Both High Tech Pet doors require a genuine MS-5 ultrasonic collar transmitter. Because PetSafe specifies compatible chips rather than every implanted chip, check compatibility for your pet’s chip before ordering.
Are the High Tech Pet doors microchip activated?
No. The two High Tech Pet models use a dedicated MS-5 ultrasonic collar transmitter to detect the approaching dog. That is different from reading an implanted microchip. Their sensing and app features may still suit a household, but buyers seeking implanted-chip recognition should compare them with PetSafe instead.
Which model is best for a large dog?
The large refurbished High Tech Pet Power Pet is the size-oriented choice in this lineup and lists a maximum weight capacity of 100 pounds. Confirm the actual opening dimensions against your dog rather than relying on weight alone, and measure the door: this model supports a maximum compatible thickness of 2 inches. It also requires the MS-5 transmitter.
Do these doors need Wi-Fi to let a pet through?
The product descriptions distinguish app-connected control from the access trigger. PetSafe requires high-speed Wi-Fi with 2.4 GHz capability for its connected features; the roll-up High Tech Pet model describes Wi-Fi app control as optional; the large refurbished High Tech Pet model lists Wi-Fi app and local panel control. The High Tech Pet doors still require their specified collar transmitter, so check each model’s instructions for the exact functions available without a network connection.
What should I measure before choosing one?
Measure the intended door’s thickness and compare it with the listed limits: 1.5 inches for PetSafe, 2 inches for the large refurbished High Tech Pet, and 6 inches for the roll-up model. Also check the manufacturer’s pet-opening dimensions against your dog’s height and width. Confirm the installation location, access method, network needs, and any separately sold accessories before committing to a model.
Conclusion
My recommendation depends on what “microchip access” means in your household. For compatible implanted-chip recognition and app-managed routines, I would start with PetSafe, provided its 1.5-inch thickness limit and 2.4 GHz Wi-Fi requirement fit. For a medium dog whose owner prefers adjustable collar sensing, several access modes, and a roll-up panel, the High Tech Pet roll-up model is the stronger match. For a large dog and a buyer who values scheduled app control and remote locking, the refurbished large High Tech Pet is worth comparing, with its transmitter, 2-inch thickness limit, and refurbished condition in mind.
Before choosing, verify pet-opening dimensions, door thickness, chip or transmitter compatibility, and included power or access accessories. Those checks matter more than the broad “smart door” label: each product solves a different access problem, and only one of these three explicitly supports compatible implanted microchips.
