Large Dog Door With Lock For Sale (2024 Update)

Being a senior widow im on my own. I installed this myself in a wood door. I thought whats the worst that could happen..buy a new door. Got er in just fine actually was easynancy

We have not installed it in the door yet…but just looking at it, it looks sturdy and indestructible, which is good, because my dog literally eats and tears the doors with the flexible plastic. He's a monster. This should do the trick. Well put together and hard plastic tri-flex door flap. Best price I can find for these is here!!Kim

I have 7 dogs of varying sizes who use this door constantly. The only fault I find is that the rubber gaskets between the slats in the door wear out . Everything else lasts a very long time. I tweaked it by putting piano hinges between the slats and that has extended its use a lot. If I could buy just that part the door would last practically forever! Even with my over-sized pack!HappyKat

Having two doggy doors has always been a problem. The prior doors were made of plastic and with our weather changing all the time, the would break apart quickly but not with these new Metal doors. And the flap is even made better. Couldn't be more pleased!!priddyclover

When purchasing they say aluminum frame. The don't tell you the security door is made of very thin PLASTIC. Another example of cheaply made American crap by a greedy, deceptive corporation. What ever happened to quality?2justftw

In our old house we had this door and loved it. The door was on the north side of the house but always kept the wind, cold and snow out! So naturally when purchasing a different house, my first purchase was another door! This truly is THE BEST door! We substituted metal screws for the plastic ones. The door held up perfectly to our 2 rambunctious Schnauzers too!Terri Nevada MO

I would highly recommend this doggy door. This doggy door is very well made and sturdy. It has a nice piece to slide in when you want to block the door. My friend came over to install it yesterday and the instructions were clear and it even came with a template to help with an uncomplicated install. Now the fun part will be getting my fur baby to use it.Dreambiz

The advertisement for this door does not give you the measurements needed for the wall or door opening which would help in determined the size you order. They are not clear on the fact that this unit is for the door and not the wall. They offer a wall kit for more money if you intend to install this in the wall. The wall kit is not needed if you are a handyman type person but you will have to go to the hardware store and buy longer screws because they are only available when you buy the wall kit. Why not just put the screws in the kit to start with.Otis2

Good study quality at a great price..just wish the flap was a little bit longer other than that I am super happy with the purchase…jajoh-4659

Lifechanging! We were slaves to our pets and now laugh at the German Shepard who jumps in and out constantly. Our cats took a minute to overcome the heavy flap but are now using regularly. Even our blind chihuahua who is very timid has even become accustomed to it.Amanda

This is a great dog door. I bought it to replace a well used older PetSafe medium door. It took a little longer to install since my door already had a previous door. Mostly it required more trim and fitment time to install, if you have a good grinding tool or hand file set it will really help. The door slides easily in place without binding. It does flex just enough that if someone wanted to enter the house from outside with it closed they could open it. But it is not meant as a security device just to prevent kids and animals from getting out which it does well. It looks great installed, very flush to the door, seals out the drafts really well. All of my dogs including my small pug size mixed breed has no problems going in and out the door. I still need to seal the outside but I'm glad I bought this door.YaheeTech

I received this locking pet door from Try it Sampling Company for free to test out. This pet door is convenient for my cat to come and go during the day. It was easy to install and use. I would recommend to install at a back door/back porch area. To me it looks better than being at a front door. Great ProductBDom

The size is perfect for my little 6 pound Malti-Poo. I wanted one that a child could NOT climb through and this one is perfect. It is not like a regular dog door where the flap in a thick piece of rubber. This door has a solid plastic flap and my dog will have to learn to use it. This morning he came in through it but has not ever gone out using it. Will take some practice.mountainmama7

Love the build! I hope my fatty can use it for as long as he lives. I gave it 4 stars because I am concerned with quality and breakage in the coldRachelle

We were having a hard time trying to teach our 4 month old puppy to bark to let us know when it was bathroom time. We felt a doggy door was the next option. We did not have a door that directly addressed our back yard. The only option was a wall doggy door. I was kind of reluctant to cut a hole in a wall. It was either a hole in the wall or get rid of the dog. Long story short is the installation was breeze and in one day our puppy was house broken. She loves her puppy door and we are very glad we made this purchase. The door is mostly plastic but is very sturdy for our 10 pound dog. I would recommend this doggy door.Ty S

This is a great door! My Frenchie figured it out, but she is a little hesitant because the magnets are so strong she doesn’t think they’ll open. She just has to put her bull head against it and she can get in and out very easily. My builder put it in and was pretty impressed with the whole thing. It was a fairly inexpensive solution to a tough problem when one has a dog but doesn’t want to ruin their house. This is replacing another great item that was a door filler for a sliding door but I got tired of walking sideways through, constantly hitting it, and jaring it out of place. Highly recommend the permanent one one. This is a great door!Hope

We love this dog door for our German Shepard and yellow lab-loved it actually- until a visiting Great Pyrenees went through it and came out the other side wearing it, frame and all. So basically it was a great door for three years until it met its match. We’ve just replaced it with this new door and it went in easily as we had the hole already cut and had installed it once before. I totally do recommend this door.Marcy K-C

After reading all of the reviews, the VERY common problem is the hinge. This is going to be my 3rd or 4th door and second to purchase (the sizable hole is hard to find a replacement for), most EVERYONE has had the exact same broken and weak point of the hinge. Some of these comments are from long enough ago, you would think that the company would look at the common problems and try and fix the issue. But they seemingly have yet to make an attempt to fix the common and perpetual problem of the hinge!!! GUYS COME ON!!!!!!!! Not adding a photo, there are plenty of them on here already.Isaac09

I've had this door for a year now, and after a year of modifying, and remodifying, I give. Simply not a great door for strong dogs. Our doberman broke the door out initially, it was put back in place. The 2nd time he broke it out some of the plastic fasteners broke off. My SO ended up modifying the door with an aluminum strip and all new hardware. It's been broken off several times even with the new modifications. The key backs fall off and we didn't end up using them anyways to begin with. The frame is solid, we got the wall kit which is flimsy and had to seal ourselves but nonetheless it's installed. I'd love to order another model that will fit the already permanent opening. As of current, our heat's turned off until we figure out what to do to fix the door. It's not strong enough for large dogs, they bust it right out!Bunnyfromdahood

Purchased the door about a month ago. We have 4 dogs ranging in size from 6.5 lb to 60 lb. All of them use the door even the little guy. The big dog did not need any training at all he instinctively new when it went click he could go! I was concerned about the reviews but it seemed to me that these were all very large dogs by height and the photos of the installs seemed low to me. I would recommend the product. No more getting up two or three times a night. YAAA I installed it myself, granted I am more of a handyman than most, but I am also over the 65 mark +. So I would expect the young bucks to do it even faster. But you do need to have a supply of the D cells. Batteries are not what they used to be and you only get about a month or a little less use. I am concerned about how long the tag battery will last, time will tell. Great Productricky5437

Excellent opening size for our pet who is 18 lbs. I purchased the Medium opening. Our sliding door is a custom height of 12 FT, not a normal height, so using the extension included with the patio panel still doesn’t reach the top of the sliding door, which of course is not the problem of the manufacturer of this product. We remedied the problem by using and cutting to size a disposable hard foam cooler, fitted with a foam edge window and door sealer in order to eliminate cool and hot air from coming in and out. It’s not perfect, but works for our pet and for our use.Grace

I currently own 2 doggy door slider inserts from a competitor brand. I got this PetSafe insert to replace one of my inserts that is worn out, and I am so glad I did! At first glance you can see that the PetSafe is far superior to my competitor door. Upon quick exploration, I could feel that the PetSafe door was much better quality. The PetSafe door itself is more substantial and heavy duty just off the bat. I like that spring-loaded panel at the top of the door is taller (than my competitor brand) so that it can accommodate more sizes of sliders. I have multiple different heights of sliders at my house so that gives me more options of doors for me to place the insert in. This is beneficial to me when I have a party for example because I can give my dogs indoor/outdoor access to a secluded part of my house when young children are over. The second part I really like is the extra security with the locking panel to close the doggy door. Whereas my competitor version only has a plastic lock that could easily be broken into by potential intruders, the PetSafe has a very secure metal pin lock. Third, I appreciate that this insert has a slight tint to it. My competitor version does not. When I open the doggy door in the early morning in my bedroom I "hook" my curtains around my original slider handle for my dogs to access the door and I go back to sleep. The tinting on this insert is at least some attempt to block out the daylight. Finally, I like that they include some weather striping to help combat some unwanted drafts. Although I would recommend to combo the weather stripping provided with foam weather stripping to really complete the seal. Overall, I highly recommend this PetSafe doggy door insert, their attention to detail is prevalent making their door superior to competitors.MamaBear34

I'm giving it three stars because it is working but for the price, I expected a higher-quality item. In some ways this unit is too thin for my patio door track and is floppy, and in other ways – specifically the attachment brackets and the door "latch" – it is too wide. I had to come up with another way to fix the panel in place, then insert foam tape because it kept flapping when the door was used or the wind blew too hard, and then buy separate security bars for the patio door. Not ideal. And I also plan that I will need to remove it if I leave for an extended period of time, as this thing is a serious security vulnerability in the home's perimeter now…not that most adults don't already fit through an extra large pet door opening. I wish this had a full closure panel – aluminum, hinged. Maybe I should have just made something custom since I can't cut a hole in the wall of my rental house for an electronic security dog door.Julie D

I have a huge 75lb male english bulldog, a 35lb corgi and an 18lb maltese. I was worried about the small ones getting through this with the double flaps and also it being the super large one, but so far they are better with the door than the bulldog is. This door is great. And since my corgi has the shortest legs I actually put the door a little lower than you are supposed to and it was totally fine. The only thing I don't like about this door so far is the wind does push open the flaps, but it's usually only when it is pretty bad out. And I haven't had a problem with my magnets falling back in line on the bottom of the flaps like some people posted about, so I really like this door!Natalie

This pet door is sturdy and durable. The template didn't line up, so we installed the door without it. I have a very large dog that plows through it at top speed and it has held up to his abuse. I have a tripod dog and she is able to use it without any problems. We did have to remove one of the flaps to get the dogs used to it with treats. It gave us a sense of comfort knowing the dogs could go in and out of the house while we were out of town and couldn't take them with us. I also have a large dog who is terrified of thunderstorms and I hated leaving her when I knew our normal weather patterns would include late afternoon storms. We researched pet doors and this one was well suited to our needs and less expensive than the electric collar types.iou2much

This door was much easier to install than my previous door. Just as advertised it prevents the wind from blowing the flaps open and letting the A/C escape. It has a weather seal already and does not need caulking. I highly recommend this product even if you don’t live in a windy area. Best design ever.evelyn

The door is well made and easy to install. we bought the large bronze. Only problem we have is that we have 3 dogs and one is a pug, other two are big 80lb even though rated for 100lb dogs and I measured them, for out dogs was a little short., I fixed by adding a small block under raising it an inch. but the 4-5' rise really does work for small dog. The XL version may have been better. But only came in white and more expensive. Been a couple weeks now and the bigger dogs are doing great. Pug, we open the slider for him. Overall well made and works well. Just a matter of getting sized right. May not work as well when you have a mix of small and large dogs.RichardJ

I bought this and installed it myself (after watching the video). Quick and easy install. Took a little coercion to get her to go through the door. She loves it now! Saves me money because now my cold air is not escaping through the open door. And best of all, no more mosquitoes and other bugs coming in my house. 🙂CindyZoey

i really like this door. no more getting up every few minutes to let the furbies out. even my lanky border collie mix can crawl through. very sturdy. would recommend.Snowcat

I ordered this Ideal Pet Door from Walmart.com to replace the same model Ideal Pet Door originally installed over 10 years ago. Walmart.com had the best price and ordering from their website is convenient with fast shipping. This Ideal Pet Door is the same model with slightly different modifications which makes it a better door than my first one. Removing the old door was very easy to do. Replacing the new door was just as easy. All I needed was a Phillips head screwdriver and my fur~kid supervising me. BTW, The original installation took an hour and was placed into a glass storm door with a solid lower panel. The Pet Door is sturdy and comes with a panel that slides into slots on the inside to block the pet door opening. It can be used when travelling or when you want to keep your pet in or out. It has a magnetic strip on the bottom part of the frame and one on the bottom of the flap which keeps the flap closed. I have never had an unwelcome guest come through the door. The Ideal Pet Door is a great value, construction is flawless and replacement parts are available. It has lasted through years of two rambunctious very bad black labs and I am replacing it by choice. It can be installed in doors, storm doors, sliding patio door inserts and in brick walls. Ideal is well know for their quality pet products and has been in business for decades. I personally wouldn't consider any other manufacturer.tami76137

Extremely easy to install.* Looks and functions better than expected in an interior door. The screws were a bit long considering the width of the door. I would suggest using shorter screws because they were hard to screw in completely, and I was using a drill to drive the screws! Overall, the door is an excellent value and I would buy another one if needed. I went with a slightly larger door than typically recommended for cats. One reason is that we are expected one cat to grow large. (We think he's a Norwegian forest cat. Before that we guessed Maine Coon.) Also, there are steps immediately on one side of the door, so I figured extra clearance would help. The smaller door would probably work OK for normal sized, fit cats. (*I traced the part that slides through the door, drilled holes where the screw posts fit through, and just cut along those lines with a jig saw. It fit right through perfectly the first time! I had a moment of minor shock when I wasn't sure if I oriented the door properly since the middle screw posts are not centered. I did, but it would have been a correctable mistake.)shuumai

Had one of these for about ten years and bought a new one. One of our dogs damaged the old one by trying to run in when the panel was inserted to keep him out while a worker was in the house. This broke two of the screws away from the plastic frame. Even though it says aluminum pet door, the only aluminum part is the white door frame. The brown frame around it is plastic as is the wall tunnel. Since we now needed to replace the flaps, it costs just as much to get a whole new one as it did to replace the flaps. Now for the new one – Had it installed for less than a month and spring loaded knob on insert panel is broken (called for free replacement under one year warranty). Door panel flap lengths are adjustable, but don't seem as thick (and durable) as old ones. If this hadn't been a replacement project of an existing one, not sure if I would have decided to install this one or look at other options.AZTom

I am on my 3rd PetSafe door. I started with a smart door but I got tired of constantly changing batteries. I have 4 dogs. I got the double flap door. After about 1.5 years the plastic piece that holds the flaps started to break (little pieces at a time). There is no replacement part for this so I had to purchase a new door. PetSafe did give me a reduced price. Now, I have gorilla tape holding my one remaining flap on this door,since the same part is breaking once again. This part is cheaply made and I feel like you should at least offer a replacement part. Now, I'm facing buying another door…again.Crazydogmom

This is a great dog door for a medium size dog. It is a deluxe unit with dual flaps for maximum weather protection. It also has a slide-in closing door with a secure lock. It looks stylish and it fits (one of our main concerns) through the section of the house that has brick. We had a professional install the unit, unfortunately, it was a little higher on the outside than the dog would have liked (see picture above) which hindered her from going back into the door. I solved this problem by ordering something called the Ten-Eighty Mini Launch Ramp for about $30. It is designed for skate boards and bicycles but it will also work in this application. I needed a little modification to sit flush with the wall and I had it carpeted so the dog wouldn't slip in cold weather. Now the dog goes in and out of the door effortlessly. I hope that this idea helps others in consideration of this great dog door.norman3670

My dog adjusted to this door immediately. No imposing flaps to push through, just a panel that raises to let the dog out and in. This product has significantly reduced the stress on our family caused by a terrier that simply loves to go in and out all day. It works perfectly and is a godsend. It is secure and only permits passage for the dog with the special collar, no other animals or vermin.littlemare2009

We have a seven month old puppy with tiny bladder syndrome so she needs to go outside frequently. However, we also have two cats with feline leukemia and they must stay inside. We ordered this door and it arrived quickly. It took a few hours to install it in the porch wall, mostly time consuming because of the type of wall we had. Once it was in, it only took a couple of days to teach the pup to use it. It’s not very loud so that is good. The delay between the time the dog approaches the door and the time it opens is fairly quick. We were a bit worried that the male cat (who wants to be the man about town) would follow the dog out because the delay from the time the dog goes out and the door shuts seems rather long. However, the cat realized pretty quickly that he couldn’t get outside by himself so he lost interest in trying after a couple of days. We are quite pleased with the dog door. The only problem we had is the collar that the sensor is on. It didn’t stay snug around her neck so she managed to take it off and chew up the sensor. We are ordering a new sensor and I am going to sew it directly onto her regular collar and hope that will fix the problem. Other than that, it is working well and we are quite happy with this purchase.dseastrider

Great idea. Our pet loves it. Since we are out in the country, other critters were always getting in the garage. Now the door only opens when CoCo is going in & out.Sandy from Vacaville

The PlexiDor is a well made item that in my opinion is worth the price. The fit and finish on the unit is excellent and it even has the person's name on it who made it. That's a pretty good sign they take pride in their work. Installation took longer than expected but that was due to my own lack of skill and not having the right tools. It only took one trip to Home Depot to get what I needed. I am really surprised by how airtight it is. The doors close tightly and I feel very little air leakage from it. I have it installed in a basement door at the bottom of stairs and even though a lot of cold air collects in this area the PlexiDor manages to seal well. I had a looked at doors and was hesitant to get one only because I was afraid of the heat loss. This is a great product and I'm sorry I didn't buy it sooner.DiVo

Pros: Very sturdy, unique design, much more attractive than traditional dog doors. Worked great for a basement door down steps because required less clearance for the saloon doors than traditional flap style. Love the security plate on rails. Cons: Price, Hard to install in older door. Best for newer smooth bottomed doors- took some work to install in an old (thinner than 1 3/4 inch) door with panels. Required building a frame around it on both sides but now that it is in looks great!Katherine R.

This is probably the best money I have ever spent. I live in GA where it gets HOT in the summer but this is insulated so well and there are no drafts in the winter. My 2 50ish lb dogs burst through this many times each day and it is indestructible. I don't have to play doorman anymore! I had one issue with the lock and they sent me a new lock mechanism right away, but I was able to fix it in about 15 minutes without needing to replace the whole lock anyway. Word to the wise, do not caulk the door on the inside so that you can remove it if/when you need to change the lock. Also, they sell a track system to add on that allows you to slide the security plate on daily/nightly (instead of screwing it on), which is super convenient and a great design.Jennifer R.

We had our kitchen remolded from top to bottom and one of my favorite things continues to be our new pet door. We had the contractors build a bench under a new window concealing the beautiful pet door in the wall. Our little Westie loves it and we do too. The door faces North West and catches a lot of wind. Only once, with high winds, have I caught it not closing completely. There is no draft and it is so secure! Worth every penny! Our contractor built a little slide to hold the cover so we can simply slide it over to lock the door if needed. Our dear Westie is now the queen of her castle coming and going as she pleases. Love it!Mary B.

This is a great product. We've bought two over the years for two different houses. Even after four years of use, it they were in almost perfect condition. This is a made in America product. The double flaps, magnets and side sweeps do an excellent job of insulating. It also is a relatively quick, easy installation with the self-framing tunnel. We highly recommend this door and should have bought it again (instead of the Endura Flap brand) for our new house.Rosebud

My dogs absolutely love the new dog door. It took a little longer to train them to go through both doors, but now they go right through it with no problems. Both dogs were already housebroken, but still had an accident every once in a while. But since they are using the dog door, we haven't had one accident. The durability of the product is excellent, the magnets are very secure and the door lock slides in very smooth. This was money well spent.Vikkie

Haven't installed it yet (have to wait for a rebuilt garage door), but it appears to be exactly what I need. Seems to be easy to install & well built.Pet Owner

I am so impressed with the clearness of the flap. My puppy had been too afraid to use my last one. Flap was hard and she couldn't see through it. Very easy set up and looks nice on the door.FinLila

Why don't you show the flap sizes? Example – 8.1 wide by 12.8 high Also, how much is the shipping – if we choose not to spend $35 or more?quikcarl

I moved houses and had a door just like this. I wanted the same type of swinging doors instead of flaps so I got the exact model that I had before. My dogs were used to it and it is a very good quality door. The first one we had was mounted on an exterior door. The new one is mounted on an exterior wall, and leads right into the dog run. It can be locked with a key for security. I love this door.vtanco

Installation was not easy. According to the instructions all you need is a jigsaw and a screwdriver…HA! False! All in all it was a 10 hour project between my Engineer dad and me (Thank God I didn't attempt it by myself!) -Cosmetically 10 out 10 -Durability 10 out 10 -Ease of Use 10 out 10 -Cost 7 out 10 -Installation 4 out 10 I shopped around a long time for a quality dog door, and this was the best I could find. A month ago when I purchased my large Plexidor w/wall insert there were no reviews, so I was little leery to spend over $500 on a DOG DOOR! In the end I went with this door for security reasons. Every year my wife and I go on vacation for a week or more and we felt more secure with this door versus the plastic versions. Our old house had a plastic dog door and that was how we used to break in when locked out. It was so easy, and therefore easy for a burglar to break in, so we made the investment in this door mainly for security reasons. NOTE: Once we received our large Plexidor my 6ft 170lbs butt could crawl through it, therefore, if not locked so could anyone else. So when you leave for vacation…lock it. It secures fairly well. Installation: You will install the door side on the inside which leaves the recessed portion facing the exterior -making it really obvious that you have a dog door. My remedy is to build & place a dog house on the exterior side of the door; so no-one would ever see or know the dog door exists! It simply looks like the dog is going in & out of his dog house! Plus it could act as a "mud" room to help clean their paws before going into the house. I actually choose to install ours into the garage, especially after the first rain when I saw all of the wet paw prints all the floor from my 80lb black lab. I don't know how people keep the floors clean when installed into a living room? The size Large door fits right in between the studs ~16" wide (as opposed to X-Large which you need to cut into the studs) & the width of the actual o…Slothneck

Since this is our third purchase, we obviously love this product. It is so nice to not have to let our dogs out and in several times during the day. The more dogs you have the better. No problems with rain. Keeps heat in our house during the winter and cold air during the summer. We currently have two Bichons.Camille B.
