Change your cylinder lock in just a few steps
The Nuki Universal Cylinder is designed as a modular solution. This means it is compatible with common cylinder dimensions and can be adapted to suit your particular door.
Note: You will need a screwdriver to change the cylinder.
- Open your door: You now have a clear view of the latch and the deadbolt that locks the door. There is a retaining screw under the deadbolt that holds the cylinder in the mortise lock in place. Loosen the screw, but don’t fully remove it yet.
- Now insert the key into the existing lock. Turn the key slightly clockwise to about 1 o’clock. Completely remove the retaining screw. Now you can pull out the cylinder with the inserted key.
Tip: Use the removed cylinder as a model to assemble your Nuki Universal Cylinder to the right length.
If the cylinder has at least 3 mm overhang on the inside of the door, you can use mounting version A. Learn more about mounting your Nuki Smart Lock. - Developed as a modular solution, the locking cylinder is easy and straightforward to lengthen or shorten to the right size.
The step-by-step instructions show how to assemble your Nuki Universal Cylinder to achieve the desired length. - The next step is to insert the new cylinder into the door.
- Now reinsert the retaining screw under the deadbolt and screw it tight.
And just like that – everything is ready for you to install your new Nuki Smart Lock.
