Helpful terms concerning doors & the Smart Lock

Cylinder: A locking cylinder is the part of the door lock where you insert your mechanical key. This cylinder checks whether your key is authorized to lock the door. There are different profile shapes such as the Swiss round profile or the UK oval cylinder.

Double cylinder: A double cylinder means that this locking cylinder can be operated from two sides. So you can lock your door from the outside and the inside.

Emergency function: The emergency function means that you can lock your door lock from the outside, even if there is a key inside the lock.

Euro Profile Double Cylinder: Euro profile refers to the profile shape of the cylinder. The Euro profile double cylinder is widely used and supported by Nuki.

Half cylinder: In contrast to double cylinders, half cylinders can only be locked from one side and are used, for example, for wardrobes or the like. Nuki does not support this cylinder type.

Handle: A handle is a door fitting that can be pressed down to open the door. Most doors in Europe have a handle on at least one side. Nuki supports doors with handles.

Knob: Front doors and main entrances are often equipped with a fixed door knob on the outside. Unlike doors with handles on the outside, unauthorized persons cannot open unlocked doors. The Nuki Smart Lock can pull the latch and is therefore suitable for doors with handles as well as for doors with a knob on the outside.

Knob cylinder: Knob cylinders are those locks/locking cylinders that can be operated from the outside using the mechanical key. Inside, however, these door locks have a knob used instead of a key. Nuki is compatible with knob cylinders of popular manufacturers.

Latch & deadbolt: The latch ensures that your door remains closed. If you press the lever handle on your door, for example, the latch is pulled and you can enter. The deadbolt locks your door. If you lock your door, for example, the lock bolt ensures that nobody can open it without a key.

Lift-up handle: A lift-up handle is a lock that requires the door handle to be lifted to lock the door. If a door has this type of lock, lifting the door handle activates the mechanical locking mechanism.

Multipoint lock: In contrast to a conventional lock, a multipoint lock locks at multiple points along the frame. Therefore, the multipoint lock offers a higher level of security. Nuki supports locks with multipoint locking.

Reversible key: A key that can be locked on both sides is called a reversible key. The keys for the Nuki Universal Cylinder are reversible keys and, therefore, very comfortable to use.

Self-locking panic lock: A panic lock is used when a door can be opened from the inside at all times, even though it is locked from the outside. In addition, the self-locking panic lock automatically locks the door as soon as the door is closed. Nuki does not recognize the locking status of the door lock.
