Review: I love the convenience - The convenience of the smart door with the smart key is absolutely wonderful. We are now able to keep our animals in or out as needed unlike before with a doggie door that does not lock. We now have no more unwanted animals coming into our home. The smart key works great and we have had no problems with it at all. The reason I purchased a second key was because it had hung too low on her collar and she liked to nibble at it. But now we have it higher up and have had no problems since then. The best thing about this doggie door is being able to have multiple smart keys so all your pets are able to use it. One great thing is that when the battery gets low you will see a flashing red light on the smart key so then you know it's time to purchase a Nother battery. The batteries are easy to find on desertcart. I highly recommend this item. We will never go back to just a hole in the wall :-) we now have more security and peace of mind and nothing is better than that.
Review: Wont open doors to Tomorrowland or the Superbowl...But really good at opening doors so your pets can relieve themselves - I attempted to use this key to get into Tomorrowland, it failed me greatly. So I then set my eyes on something more reasonable: getting into the Super Bowl. Also a fail. Turns out the smart key isn't some kind of super key that unlocks all of your dreams, its actually a key you hang around your pets neck that allows them to go in and out of the Petsafe doggy door (sold separately). That it does exceptionally well. While not getting into all of the exotic locales of my choice has been highly disappointing, seeing Crackers excitement every time he runs outside to pee leads me to believe that this key, while not the key to all of your dreams, may indeed be the key to unlocking all of your pet's dreams.

## Questions & Answers

**Q: Is there a warranty for the key? Mine quit working but the 2nd one is working fine (I've tried 2 other batteries)**
A: Little warranty. Call first and they can walk you through it to make sure all is being done correctly. Could be the battery. Could be workiking but key not lined up to door properly to work.

**Q: How long does it take for the door to lock behind Your pet?**
A: Thank you for asking about this!  Though we do not have a specific timeframe for this, the door will lock several seconds after the key is taken out of range, typically within around 10-15 seconds.

**Q: Dimentions of opening of largedoor**
A: Thanks for your question, Tina! The flap opening of the Large SmartDoor measures approximately 11” x 16”.

**Q: I actually have 7 dogs. Can i program all 7? I saw it said 5**
A: This is a great question, Kim!  The SmartDoor™ can only five programmed keys, so you would not be able to have separate keys for seven dogs programmed to this door.  We do apologize for any inconvenience this causes.

### ⭐⭐⭐⭐⭐ I love the convenience
*by A***K on June 24, 2016*

The convenience of the smart door with the smart key is absolutely wonderful. We are now able to keep our animals in or out as needed unlike before with a doggie door that does not lock.

### ⭐⭐⭐⭐ Works great for dogs, the cats can’t get in, and it prevents drafts.
*by M***E on June 1, 2023*

Our previous dog door was easy enough for the cats to get in- they are outside cats! It also let cold air in on windy days. With this unit, only the dogs use it and it prevents drafts. The only problem we have had is one dog lost her collar (the lawnmower found it) and we had to replace collar and the transponder. The dogs learned to use the door quickly. Living in the country, I was always worried about other critters such as possums or skunks getting in- not anymore.
