Do you have a holiday apartment which you share or rent out? Handing over the keys is one of the most laborious matters with holiday or Airbnb apartments.

With Nuki this problem is history: with digital access permissions you decide from afar who, when and how long people get access to your property.

What is Auto Unlock?

When you activate the Auto Unlock function, Nuki unlocks your door automatically when you come home. Your smartphone remains in your pocket.

Elektronisches Türschloss Auto Unlock

Nuki uses the location of your smartphone to detect when you leave your home.

If you approach your home again, the Nuki app is preparing to open your door. When you reach your door, Nuki unlocks it automatically via Bluetooth.

The next Auto Unlock will only be triggered when you move away from your home for more than 100 metres and enter again. So unwanted locking operations are avoided.

What experts say

"As an additional opportunity to open the door; even my wife who tends to be sceptical towards technology really likes to use the Nuki. The most popular use case is when we arrive home packed after shopping. The door opens automatically, we get out of the car and enter our house without searching for a key or the smartphone." read whole article
"The Nuki Smart Lock makes your daily life easier - when you use the Auto Unlock function you don’t even have to set aside your shopping bags and you still get into your apartment without any problems. Also opening and locking the door has always worked in the test without any problems." read whole article
"I don’t want to get along without Nuki anymore. The Smart Lock is tremendously practical. Personally, I really like the Lock ‘n’ Go function. Pressing on the button on the Smart Lock twice, Nuki locks the door after 20 seconds. So leaving the apartment is very easy and relaxed and you don’t have to lock the door manually." read whole article
"The concept of the Nuki Smart Lock is well thought through. Especially the installation is very easy and done within minutes. Also the installation and use of the app is manageable easily. It is a plus that the Smart Lock can also be used without the Bridge. A clear recommendation to buy for Nuki." read whole article
"Nuki has been integrated in my daily life and the thought to open the door with a physical key was completely rejected. Since weeks I just tap on my wrist and the door is opened - or closed and locked. As the Apple Watch is permanently connected via WiFi to the iPhone, the key on the wrist can be conveniently used at all times." read whole article
