Common questions
What should I check before choosing between Nuki Smart Lock (US Deadbolt) and Yale Assure Lock 2 with Wi-Fi?
Start with the exact door and lock model. Check the keypad, bridge or hub needed for your chosen booking connection. Decide which system should create and remove guest codes. A compatible brand name alone does not confirm that the full setup will work.
How should I plan backup entry with Nuki Smart Lock (US Deadbolt) and Yale Assure Lock 2 with Wi-Fi?
Check how the exact model lets guests in if the main method fails. Test the guest steps before arrival and arrange local help. A code may work offline but still need an internet link for you to change or remove it.
Will Nuki Smart Lock fit any US deadbolt?
No. Nuki’s US guide calls for a single-cylinder deadbolt: a key outside and a thumbturn inside. The door’s swing and nearby hardware also affect fit. Use the US guide and measure the needed space before you buy.
Which Yale Assure Lock 2 setup does Airbnb support directly?
Airbnb lists Assure Lock 2 with Wi-Fi, including the Wi-Fi Touch and Plus models. It allows built-in Wi-Fi or a Connect Wi-Fi Bridge. The listing must be in the US or Canada and meet Airbnb’s other rules. Bluetooth alone is not the same setup.
