Here is my experiences with my High Tech Pet Door, Any problems will be either within the motherboard or the wiring harness, both of which you can buy from High Techand they are not difficult to replace. Also, if the installation screws are too tight, it will affect the operation of the door. Screws should be snug only. When mine was first installed, it did not work very well. Sometimes it worked and sometimes it did not. I took a look at the instructions (I had paid a friend to install mine). The bottom of the sliding door is supposed to be the distance from the bottom of your dog's chest to the floor. Mine had been mounted at ground level. Which is what other people on you tube seemed to have done. Maybe that is alright with the smaller dogs? But, for my 65 lb dog, High Tech said that would affect the function of the dog door as the signal bounces off the hard floor surface. It did fix the operation problems that I was having. I took out the door and added a 2x4 between the 2 studs at the proper height to remount the dog door for the height olfor my dog. It worked great for the next 14 years. I did have to replace the mother board after 10-ish years, the door started not working very well when it got really cold or snowed a lot. That fixed it right up. Then it started not going up and down very slowly and sometimes not at all, or even half way and then stop. I then replaced the wiring harness. I did read or the High Tech person on the phone, told me that when replacing the harness to follow the same routing of the 2 wires. They also told me to make sure the screws were only snug and not over-tightened. Good information. It has been my experience that most folks overtighten as a norm. I never expected this door to last as long as it did. I have been totally pleased with this dog door. The freedom it provides to you and your dog is a wonderful thing! I moved and left the door installed. I purchased another one for the new house did not know what to do with that wall if I took the door with me? I am about to install it. I love the High Tech pet door. I have the PX2 and will not, NOT have a High Tech Pet Door as long as I have a dog! I just viewed Mimi's KZfaq on how to hack the batteries. My battery lasted 6 months usually. I still do not like spending that much money on a battery. Thanks Mimi! My dog would open the door and stick her head out stand there just looking around outside a lot! And vice versa. I also had a 2nd collar for friend's dogs that came over, because my dog would deliberately go through the door when the other dog was on other side of the room, to mess with them, so they couldn't tag along with her to go outside. I figured my dog needed to learn to share instead of being a brat! The folks at High Tech Pet are very helpful on the phone and very knowledgeable about their products. You don't find that very often these days.

very well done about the information it does help others to install thanks

In the area of the tunnel, just use some short self tapping screws to secure the tunnel to the parameter of the dog door frame, then caulk it. Also, buy a small section of really low cut carpet and use adhesive caulk to glue the carpet to the inside of the tunnel. No need to carpet the inside top of tunnel.

I’ve had mine for 5 years, it’s started leaking. I caulked, still leaks. Purchased a new tunnel and caulked. Still leaks. Leaking on bottom, I even caulked the transmitter to see if that was problem. Still leaking. I’m hoping if I purchase a new door it will fix the issue.

Nice video! Thanks...looks like you're in a cold climate. How'd it do in the cold? Thanks

Are there only eight screws? Trying to remove my door to replace the circuit board, and I can't get it to budge.

So it should be easy when you install this on a door? Planing to get one but the new version with wifi control

Why do you need to plug it in or use batteries? Can’t you just lock it when you don’t want them using it? Is it so other animals can’t get in?

Where you buy the sleeve?

How has it been holding up?
