Automate Access to Your Vacation Rentals with Nuki Smart Locks and Rental Ninja

Simplify check-ins, increase security, and save time with this smart integration between Rental Ninja and Nuki.

Sound familiar?

Apartment 1: The guest's flight is delayed. It's 11 PM and you're standing at the door with a bunch of keys.
Beach house: Cleaning staff needs to get in, but nobody left them a spare key.
Apartment 3: A plumber needs to fix an urgent leak… who lets them in?

These situations are still part of the daily grind for many property managers. Not only do they waste your time and cause stress—they compromise security and guest experience.

At Rental Ninja, we get it. That’s why we’ve integrated our platform with Nuki, Europe’s leading smart lock, so you can forget about keys, manual handovers, and complications—forever.

The real problems of manual key management

• ⏳ Time lost coordinating check-ins and key pickups.
  
  
• 🔑 Risk of lost or copied physical keys.
  
  
• 😡 Poor guest experience, especially with late arrivals.
  
  
• 🧹 Difficult access coordination for cleaners and maintenance.
  
  
• 🧩 Lack of centralization: one system for bookings, another for locks—it gets messy.
  
  

What is Nuki and why is it ideal for vacation rentals?

Nuki is a smart lock installed on the inside of the door, with no need to replace your lock cylinder. It connects to the internet and allows you to:

• Generate unique, time-limited codes
  
  
• Grant or revoke access remotely
  
  
• Track access history
  
  
• Avoid being physically present for check-ins
  
  

And best of all: it’s fully integrated with Rental Ninja, so you can manage all your access control from the same panel you use to manage bookings, payments, tasks, and your team.
