AGE OF ULTION - Ultion Nuki

The Ultion Nuki is simple to fit, works on most doors and makes locking and unlocking your door effortless

- 

It's astonishing so many of us still use keys to open doors. Simple pieces of steel that manually turn a lock mechanism - it's archaic. Luckily, Ultion's Nuki smart lock can make updating a breeze: it fits on almost any door, installs in minutes and, thanks to its modular design, is very affordable.

There's an installation checker on the Ultion website to ensure that the Nuki will work on your lock, but in most cases, the answer is yes. For the actual installation process, you can opt for the hands of one of its installation partners but on most doors, you should be able to easily install it yourself. You simply replace the back of the lock with Nuki holder and screw it in. The Nuki device then just clips into place, slotting the end of the cylinder into it.
